Parts of the Nervous System

Identify each part of the nervous system. (The correct answer is given in parentheses.)

      Exerts control over all parts of the body (nervous system) Consists of the brain and the
       neurons extending throughout the body.


      Controls all voluntary movements, thoughts, and registration of incoming information
       (CNS) Consists of the brain and spiral cord


      The site where the processing of all central nervous system activity takes place (brain) An
       organ roughly half the size of a loaf of bread that constantly controls behavior.


      Main carrier of messages between the brain and the body (spinal cord) A bundle of
       nerves that leaves the brain and runs down the length of the back; transmits messages
       between the brain and the body.


      Registers information and controls movements outside the central nervous system
       (peripheral nervous system) Made up of long axons and dendrites, it contains all parts of
       the nervus system other than the brain and spinal cord.


      Takes charge of the body’s involuntary functions outside conscious awareness
       (autonomic nervous system) Concerned with the parts of the body that function
       involuntarily without our awareness


      Coordinates incoming information from the senses and sends instructions to the muscles
       and glands (somatic nervous system) Specializes in the control of voluntary movements
       and the communication of information to and from the sense organs.


      Increases the heart rate in an emergency situation (sympathetic nervous system) Act to
       prepare the body in stressful emergency situations, engaging resources to respnd to a
       threat.
   Stimulates digestion of food when the body is in a state of rest (parasympathetic nervous
    system) Acts too calm the body after an emergency situation has engaged the
    sympathetic division; provides a means for the body to maintain storage of energy
    sources.
Parts of the Brain

Describe one daily routine you do that uses each of these parts of the brain (you can use one
example or five separate examples).

1. Cerebellum.




2. Hypothalamus.




3. Reticular formation.




4. Limbic system.




5. Frontal lobes.
Parts of the Endocrine System

Identify each part of the endocrine system.

      Major chemical in the endocrine system


      Regulates the pituitary gland


      The body’s “master gland”


      Hormones involved in sugar metabolism


      Female reproductive organ


      Organ that produces hormones involved in sugar metabolism


      Gland that controls the metabolic rate


      Nervous system organ that is also in the endocrine system


      Male reproductive organ


      Type of regulation in the endocrine system


      Gland involved in controlling body size


      Involved in regulating the body’s reaction to stress
