is a complex, highly organized system that coordinates all of the activities of the body
neuron
nerve cell, it consists of a cell body containing a nucleus
nerves
are combination of many nerve fibers located outside the brain and spinal cord.
central nervous system
consists of the brain and spinal cord
peripheral nervous system
consists of nerves
autonomic nervous system
system that controls involuntary body functions
brain
is a mass of nerve tissue well protected by membranes and the cranium
cerebrum
the largest and highest section of the brain
cerebellum
the section below the back of the cerebrum
diencephalon
the section located between the cerebrum and midbrain
thalamus
acts as a relay center and directs sensory impulses to the cerebrum
hypothalamus
regulates and controls the autotomic nervous system, temp., appetite, water balance, sleep, and blood vessel constriction and dilation.
