The general functions of the hypothalamus are of extreme importance for the body, such
as:
pituitary gland regulation blood pressure regulation hunger and salt cravings
feeding reflexes thirst body temperature regulation
hydration heart rate bladder function
water preservation hormonal/neurotransmitter regulation ovarian function
testicular function mood & behavioral functions wakefulness
metabolism sleep cycles energy levels

hypothalamus , an important supervisory center in the brain , rich in ganglia, nerve fibers, and synaptic
connections. It is composed of several sections called nuclei, each of which controls a specific function.
The hypothalamus regulates body temperature, blood pressure, heartbeat, metabolism of fats and
carbohydrates, and sugar levels in the blood. Through direct attachment to the pituitary gland , the
hypothalamus also meters secretions controlling water balance and milk production in the female. The role
of the hypothalamus in awareness of pleasure and pain has been well established in the laboratory. It is
thought to be involved in the expression of emotions, such as fear and rage, and in sexual behaviors.
Despite its numerous vital functions, the hypothalamus in humans accounts for only 1/300 of total brain
weight, and is about the size of an almond. Structurally, it is joined to the thalamus ; the two work together
to monitor the sleep-wake cycle. http://www.encyclopedia.com/topic/hypothalamus.aspx
The hypothalamus is a highly complex structure in the brain that regulates many important brain chemicals.
Malfunction of this area of the brain may produce endocrine disorders, impaired temperature regulation,
headaches, and other problems. http://www.centurahealthinfo.org/In-Depth%20Reports/10/000337.htm
Deep within the brain humans carry a relic of evolution called the hypothalamus, which prepares the body for
starvation situations by enhancing performance and conserving energy. Check out this clip to learn how a lost
caver was saved by his hypothalamus. http://videos.howstuffworks.com/discovery/30913-how-the-brain-works-
