TWO LEADERS OUR BODY: Hypothalamus gland And the pituitary gland The fact that you can sit comfortably in your chair and read the sentences is due to the system that regulates the balance in your body for your benefit. For example, no matter what the temperature outside, your body should always be kept at a constant temperature, usually between 36.5 and 37.5 degrees. The decline and rise in body temperature can lead to sudden death. The body temperature of a healthy person, thanks to this system, changing at most 0.5 degrees. In the same way, the blood pressure in the blood vessels, the amount of fluid in the blood, and the speed of cell function should be carefully measured, and the balance that is maintained at all times. Let us imagine the effort required to maintain this balance is made. First, imagine a sensitive thermometers in several places in the body, the use of devices to measure the viscosity of blood in the veins, and a mini laboratory to control the speed of cell function. Then imagine thousands of devices located at various points in the body every second should be appropriately assess and convey the information it receives to a highly sophisticated computer. However, it is not enough these studies were made, while at the same time, it should be well known, based on existing data, what actions need to be taken and what kind of command that needs to be given to the cell which. Of course, even with today's technology, it is still not possible to put thousands of thermometers, mini lab, and pressure gauge in the depths of the human body. However, a special system with a sophisticated design that may have been placed in the depths of the human body from birth. Thousands of postal recipients to measure such things as temperature and pressure of the blood vessels. These posts to send information to a particular computer. This computer is in the brain called the hypothalamus. Hidden manager Your Body: The hypothalamus gland The hypothalamus is the general leader of the hormone system, and he has the important task of ensuring stability in the human body. At any time, the hypothalamus examine the messages that come from the brain and from the body. After that, put into effect several functions, such as maintaining stability in body temperature, blood pressure control, ensure fluid balance, and even proper sleep patterns. The hypothalamus is located directly below the brain and the size of a shelled walnut. A large amount of information in relation to the state of the body is sent to the hypothalamus. This information is delivered to it from any point in the body, including the sensory centers in the brain. Then hypothalamus decipher the information it receives, decide the action to be taken and the changes that must be made in the body, and make certain cells run decision. The basic thing to note here is: the hypothalamus was an organ composed of cells unconscious. A cell not knowing how long humans have to sleep, he can not count how many should be body temperature. Cells are not able to make the best decision based on the information available, and can not make any other cell in the body to run farther apart that decision. However, cells in the hypothalamus act in a remarkable way conscious to ensure that a balance is needed in the body awake. On the following pages, we will examine in detail the extraordinary activity shown by these cells do not realize this. One of the most important functions of the hypothalamus is to bridge the hormonal system and other systems that regulate and maintain the body's nervous system-ie. The hypothalamus is not only regulate the hormonal system, but also the nervous system with a high level of expertise. The hypothalamus has a very important auxiliary role in regulating the body; maid was delivered to certain parts of the decision that has been taken. For example, when there is a sudden drop in blood pressure, the pieces of information delivered, and the hypothalamus of the pressure changes; ago hypothalamus decides which actions should be taken to raise and communicate its decision to the assistants. To carry out the decision, aides know that cells which have received the order. He wrote messages in a language understood these cells and immediately convey all the message. Target cells obey orders received and taking appropriate action to raise blood pressure. Maid hypothalamus is the pituitary gland, which is also very important influence in the hormonal system. Between the hypothalamus and the pituitary gland are amazing communication system. Both pieces of meat are actually communicate like two humans are conscious. The hypothalamus has comprehensive control over the pituitary gland and the release of several important hormones. For example, a child in the hypothalamus during the development of the pituitary gland to send messages to the command, "release growth hormone" and then the pituitary gland releases growth hormones exactly as required. Something similar occurs when the body's cells need to work faster; here there are two levels of command. The hypothalamus sends a command to the pituitary gland which in turn transmit orders to the thyroid gland. The pituitary gland releases thyroid hormones in the right amounts and the body's cells begin to work faster. When the adrenal glands (which produce several essential hormones) should be enabled or reproductive organs must produce hormones, hypothalamus again sends a message to the pituitary gland, which directs the message to the appropriate area and make sure that the hormones that are needed in the body was released. The hormones produced by the pituitary gland hypothalamus to regulate, among others: • growth hormone releasing hormone • thyrotropin releasing hormone • corticotropin releasing hormone • gonadotropin-releasing hormone In some ways, to participate in the activities of the cell, using two hypothalamic hormones it produces itself. To save these hormones, the hypothalamus first sent to the pituitary gland, and then, when needed, to ensure that the hormones released by the pituitary gland. These hormones are: • Vasopressin (an antidiuretic hormone, the hormone retaining water) • Oxytocin Both molecules hormone produced by the hypothalamus is very small. One of them is only three amino acids. Hypothalamic hormones differ from other hormones not only because it is small, but also because of the distance of the body. Hormones usually move to distant areas of the gland where it is generated into the specified organs. However, hypothalamic hormones reach the pituitary gland to penetrate only a few millimeters thick capillaries. This hormone never enters the general circulatory system. The hypothalamus produces hormones that activate the pituitary gland, and when required, producing hormones also stop the pituitary gland at the right time so as not releasing certain hormones. In this way, the hypothalamic pituitary gland regulate the activities entirely. Orchestra conductor Hormones: Pituitary Gland The pituitary gland is a small piece of flesh is pink for beans, weighing half a gram and is connected to the hypothalamus in the brain by a rod. Thanks to this relationship, taking orders from the hypothalamus gland to produce a hormone that is needed. This pea-sized pituitary gland is a big influence on the human body and shows the amazing functions that have been (and still is) the subject of scientific research for many years. This small piece of flesh has received much attention in the scientific world. The pituitary gland is also admired for its properties are remarkable. For example, the pituitary gland is referred to as "the conductor of the orchestra endocrine (hormone)". This gland is also praised as a "major glands". At the same time, the pituitary gland is also known as an "extraordinary biological miracle". The pituitary gland deserves praise is due to the 12 different hormones it produces and the control it exercises over the hormonal system. Gland not only produces hormones that affect specific tissue cells, but also regulate other hormonal glands that far away. If we remember that the hormonal glands are the organs that regulate the activities of cells in the body to give a specific command, the importance of the pituitary gland becomes clear. Because not stop giving orders to the various cells in the body, the pituitary gland also gave orders to hormonal glands that transmit orders to other cells in the body. Thus, the pituitary serves as a leader of leaders. For example, it sends a command to the thyroid gland thyroid hormone release when needed. In the same way, gave commands to the pituitary adrenal glands, testes in the male body, as well as the ovaries and mammary glands in the female body. An important question is: how the pituitary gland and the cells that make it up knowing "adrenal gland function," how "the gland to function", and "the sign required to activate it?" How do the cells that make up the adrenal glands to understand and translate the commands sent the pituitary gland, and why stick with it? When we consider this issue in detail, we will see that this miracle wider dimension. A hormone produced by the pituitary gland is designed to fit place inherent in the destination cell. However, no cell pituitary gland hormones ever seen where the message is sent. Pituitary cells can not know the design of receptors on the cells that make up the adrenal glands. This can be compared to a person who goes to a home thousands of miles away in another country, who finds himself at the front door that has never been seen, but it has a key that fits the lock at the first try. How do the cells that make up the pituitary gland can figure out how to make children fit the lock key-lock that has never seen the cells? Another important thing is not to be an error in the system. If a key is not to open the door of the destination (ie, if the hormone produced is not performing its functions in defined areas), there was a death. Suppose a hormone produced by the pituitary gland does not work on the adrenal glands, the body can not survive. To further understand the magic of this system, we can use the following ways: stand in front of a mirror, place your finger on a spot between your eyes. Five to six inches behind the point, right in your skull, there is a piece of flesh, the size of a kidney bean, called the pituitary gland. Then, put your other hand on the abdomen. Just below this hand, in the stomach, there is a pair of kidneys. At the top of each kidney, there is a gland the size of a walnut and weighs about 4-5 grams called the adrenal glands. Both pieces of meat can communicate with each other. They are not aware that people can talk to each other, but the two groups of cells. Furthermore, this communication system, together with the effects it produces, is the result of advanced technology that is not even human beings. The fact that the two pieces of meat deep inside our body communicate and understand a miracle to contemplate. On the other hand, if you do not study biology, he is aware that such an organ in the skull below the brain. Most ordinary people do not even know that the pituitary gland is a very small piece of flesh beneath the brain that keeps us alive by constantly sending messages and commands to the body. In addition, people really do not realize that all that happens. If the gland is not performing its functions, this person will die in a short time. If you see a moment from this point of view the person next to you, you will understand how weak and dependent human beings to God, our Creator. Hormones Produced by Pituitary Gland Before contemplating further names of pituitary hormones, it is worth repeating that the goal of this book is to see the amazing things that happen in the hormonal system that surprised even the scientific world, and observe more closely the greatness of God's creation. For this reason, it is better to focus on how the system works rather than the names of the hormones. The terms Greek and Latin are used in medicine and biology to be a barrier for many people. And sometimes the terms of Greek and Latin is just a mechanism to make the course more difficult to understand (or hinder us appreciate the miracles that occur in processes skyline). Most medical experts and biologists may not have understood the wonders around them precisely because of the charm of these terms. For example, they know the details of how form and function of the pituitary gland, but never thought of intelligent awareness sources indicated this little piece of meat. For that reason, we do not need to repeat that scare readers who are not familiar with medical readings to prepare a special room for the meaning of these terms. We will only briefly mention the names of hormones and on the following pages we will see the great wonders of hormones caused it. The pituitary gland is composed of two parts: glands front (anterior) and back (posterior). Each part produces different hormones. Pituitary gland Home Front of the pituitary gland produces six different hormones that have specific functions. Some hormones that work on other hormone glands called "tropic hormone". This hormone is designed to regulate the hormonal system. In the following pages we will study the tropic hormone functions together with the structure and function of glands that produces hormones. Another group of these hormones stimulate the body's tissues. The names of the following hormones: The hormone that stimulates the endocrine / hormone other (tropic): 1. Thyroid stimulating hormone (TSH) 2. Adrenal gland stimulating hormone (ACTH, adrenocorticotropic hormone) 3. Follicle stimulating hormone (FSH) 4. Luteneizing hormone (LH). The hormones that work on the body (non-tropical) 1. Growth hormone (GH) 2. The hormone prolactin (PRL). Rear Pituitary Gland The back of the store where the pituitary gland is a hormone produced by the hypothalamus. In appropriate circumstances, these hormones are released by order of the hypothalamus. These hormones are: 1. Vasopressin (antidiuretic hormone) 2. Oxytocin Miracle Growth: Growth Hormone A baby is a year old and weighs nearly twice the length of one and a half times as he was born. Within a year, the weight up with astonishing speed. He also grows longer, and the body grows in proportion. What causes a newborn that weighs 3 pounds and can grow to 50 centimeters long into adult weighing 80 kilograms and 1.80 meters twenty years later? The answer to this question is hidden in the growth hormone that is found in an amazing molecule secreted by the pituitary gland. In order to become an adult, a child should grow up. The growing process occurs in two ways. Some cells have an enlarged; Other cells divide and multiply. That regulate and ensure both of these processes is a growth hormone. Growth hormone is released from the pituitary gland and affects all cells in the body. Each cell knows the meaning of the message sent to him from the pituitary gland. In keeping with this message, it grows or breed. For example, a newborn baby's heart is about one-sixteenth the size of a human heart, but the total number of cells in the baby's heart is the same as the adult heart. With the development of the body, growth hormone affects every cell of the heart. Each cell is developed in accordance with the orders given to him by growth hormone. As a result, the heart grows into an adult heart. Proliferation of nerve cells stops when the fetus is six months old and still living in the mother's womb. From that time until birth, and from birth to adulthood, the number of nerve cells remains the same. Ordered growth hormone nerve cells to increase in size. When the growth period ends, the nervous system has reached the final shape. Other cells in the body (eg, muscle cells, and bone) to divide and proliferate during infancy. Again, growth hormone that informs these cells how much should be split. Based on this, we have to ask this question: How might the pituitary gland to know the exact formula that determines the division and growth of cells? Amazing that this piece of flesh, the size of a chickpea, set all the cells in the body and make it grow by splitting or enlarge themselves. Another question that must be asked is: who commissioned a piece of flesh with this function? Why lifetime of these cells send messages that instruct other cells to divide? Here, again, we see the greatness of God's creation is flawless. The cells are located in a small area to make sure regular division trillions of other cells. However, these cells can not be observed from outside the human body to determine how much the body to grow and when to stop growing. Unconscious cells, in the darkness of the body, even without knowing what it does, producing growth hormone (and stop producing it) when necessary. A perfect system has been created to control each stage of growth and the release of this hormone. It is one of the wonders that the growth hormones ordered some cells to increase in size and the other to multiply by cell division due to the hormones that reach each cell type are similar to each other. How the cell that receives the command must react is written in the genetic code. Growth hormone issued an order to grow, how that growth will occur in the cell recorded. It shows the strength and greatness of creation at any point in the development of the human body. However, one thing that is very important is the fact that most of the growth hormone affects the body's cells. If the number of cells abide by growth hormone and the other does not, the result is a disaster. For example, heart cells obey the growth hormone, but the cells in the rib cage refused to multiply and grow, what would happen? The developing heart will be squeezed in the chest cavity that is too small and dead. Alternatively, the nasal bones grow but the skin over it stops growing, the nasal bones will tear the skin so open. Alignment growth of muscle, bone, skin and other organs ensured by adherence to every cell in the human growth hormone. Growth hormone also gave orders for the development of cartilage at the ends tulang.1 Cartilage is like the state of a newborn who has not been formed, and if it does not grow, the baby can not grow. Here, cells cause the bone to grow in length, but how do these cells know that the bone should grow in this way? If the bone grows to the side, the leg would not elongate; may even tear the skin and be exposed. However, everything has been planned and the plan was written in the nucleus of every cell. Another astonishing fact about growth hormone is when he is released and how much. Growth hormone is released in the right amount and at the time of most active growth period. This is very important because if the amount released more or less than required, the result will not be as desired. If too little hormone is secreted, dwarfism occurs, and if too much, gigantism (giant growth) result.2 So, for that reason, a very special system has been created to regulate the amount of hormone released in the body. The amount of the hormone that is released is determined by the hypothalamus, which is known as a regulator of the pituitary gland. At the appropriate time for the release of growth hormone, the hypothalamus sends "releasing hormone growth hormone" (GHRH) to the pituitary gland. And when too much growth hormone is released into the blood, the hypothalamus sends a message (somatostatin hormone) to the pituitary gland and hormone release slows pertumbuhan.3 However, how the cells that make up the hypothalamic growth hormone to know how many there should be in the blood? How do the cells that measure the amount of growth hormone in the blood and make decisions based on that amount? To explain how great a miracle, let us consider an example: Imagine that we have used special equipment and shrink the size of one's body to split millions of its original size, which is the size of a human cell. We put these people in a special capsule in addition to a cell in the hypothalamus. The task is to calculate the amount of growth hormone molecule in the capillaries that pass in front of him. He determines if there is a reduction or increase in the number of molecules. Well known that there are thousands of different substances in the blood. There's no way a human being (if not an expert in this field) to know from the molecular structure if something in front of her growth hormones or other substances. However, the people we put in the hypothalamus must recognize certain growth hormones are among the millions of other molecules. In addition, it should always check the amount of hormones. How can unconscious hypothalamus to perform this task, which seems very difficult even for humans? How does it all the time to measure the amount of growth hormone in the blood? How does it distinguish from other molecules of growth hormone? These cells to recognize molecules without eyes, or brains to assess the situation. But they put the commands given to him in a perfect system of God's creation. Growth hormone is released not only in their infancy, but continues into adulthood. In such circumstances, you would expect people will continue to grow and become huge. However, this does not occur.4 When a person reaches a certain size, the cells no longer divide and grow. Scientists still do not know why this happened. It is known that due to the highly specialized systems, cells are programmed not to divide and grow after a certain period. In such circumstances, one should think about the Power that creates perfect program. It shows us another miracle of God's creation. Not so hard to understand the importance of the trillions of cells stop dividing and growing in a timely manner. If some cells do not stop dividing as other cells, the result will be horrible. For example, if the eye cells continue to divide and multiply after cell groups are ending, would be squeezed in the eye socket and broken. After discussing the trillions of cells suddenly stop their activities, there is something else worth remembering. Cancer is a disease that we have been fighting for decades and still can not be conquered; This is caused by the cells continue to divide uncontrollably. This example allows us to better understand the careful balance within the body. In adulthood, growth hormone continues to influence in some specialized cells and stimulates these cells in order to divide and multiply. This is another miracle of creation aimed specifically. This cell division no longer causes growth of the body, but to repair and regenerate the body. For example, skin cells and red blood cells continue to divide so that our bodies get 200 million new cells every menitnya.5 These cells replace old cells and damaged. In this way, the total number of cells remains the same. Growth hormone has a special design that produces a number of factors used in cell division and growth. For the division and growth of cells, it is first necessary that the cells increase in size, which is possible only by increasing the amount of protein. Therefore, a special function in growth hormone accelerates protein production in cells. It is known that protein production occurs as a result of a complex process. Scientists have been able to understand some of the elements in this process after years of research. To produce one molecule to increase activity of this system, it is important to know all aspects. The fact that growth hormone has a design that makes it able to accelerate the production of a protein is evidence that the system that produces the protein and growth hormone is created by God so as to work together harmoniously and perform the function of command. Growth hormone not only ensure the acceleration of protein synthesis, but also ensures that the amount of raw material required for this purpose to enter the cell. The main ingredient is a protein needed for the synthesis of amino acids, the building blocks of protein compounds. As if knowing this information, growth hormone stimulates the cell membrane in order to receive more amino acids. To accelerate protein synthesis, cell metabolism must be accelerated and, until now, growth hormone in collaboration with other hormones. Thyroid hormones are released during growth accelerates metabolic activity of cells. For everything to happen, one more very important thing that is required is power. Even if all the systems we have mentioned so far is perfect, all is useless without a source of energy. Without power, the growth process can not happen. But the human body has been perfectly planned so that these needs are also available. Besides all these complex functions, growth hormones run another very important task. It ensures the release of fat molecules that mix with the blood. In this way, each molecule will serve as a fuel source to meet the needs of the cell for power. When reading about the activity of growth hormone in the body, it is important to recall that doing all this is lifeless molecules formed from the combination of several atoms that have no hands, eyes, or brain. Amazing that inanimate objects can know when and where to go in the body, and when, how, and in what way to stimulate her. Atoms unconscious can not write and send each other messages, but this wonderful event occurs when the number of interacting molecules. Molecules immediately know what to do and then do it. For example, when interacting with growth hormone, some molecules begin to divide. Others decide to absorb more amino acids. And for that, just need to respond to growth hormone. How can a conscious activity and organized running nonstop in the body? To claim that all these wonderful balances formed over time by the operation of chance in the face of scientific fact and logic. Therefore, a deficiency can destroy the entire system. In order to survive, the whole system and all the organs of a creature should be formed at once. Every thing about the meticulous balance of growth hormone and related, that we have reviewed so far, points to the fact that man is created to perfection as a human being complete. About the wonder of creation, God said in the Qur'an: "It is God Who has created, Yang held, which forms a manner, which has the names of the best. Glorify Him in the heavens and the earth. And He is the Mighty, the Wise. "(Surat al-Hashr, 59: 24) Prolactin Hormone This hormone is released by the pituitary gland that stimulates the mammary glands in the female breast to produce milk. Milk production is controlled by the hypothalamus. How prolactin function will be explained in detail in the section "milk miracle." Hormone Oxytocin This hormone is produced by the hypothalamus and stored in the pituitary gland behind. When needed, oxytocin is released by the pituitary gland when it receives nerve stimulation of the hypothalamus. Functions include wrinkled milk ducts. Other functions of oxytocin in milk formation is described in detail in "The Miracle breast milk." In addition to its role in the formation of milk, the hormone oxytocin has other duties. It ensures the uterine muscle contraction at birth to facilitate the delivery process. During labor, oxytocin production increased rapidly. At the same time, the muscles of the uterus to develop sensitivity to the hormone oksitosin.6 During the birth process, some women are given an injection of oxytocin to help relieve pain and speed up the process. In order for the production of natural oxytocin, the cells that make up the hypothalamus to know all the elements involved in the birth process that occurs at a distance from him. These cells should know that birth is a difficult process and that must contract the uterine muscle to push the baby out. In addition, cells must recognize that chemical production is necessary for the contraction of the uterine muscle tension, and should know the correct formula. He Who made plans in the production of the hormone oxytocin gene hypothalamic cells, which creates the baby to be born into the world, her mother, the mother's womb, and the cells of the hypothalamus, is God.
