Organization of the nervous system
CNS main structures and functions
Functions
as the integrating and command center for the CNS
Structural components
Brain
Spinal cord
PNS main structures and functions
Structural component
Nerves
Ganglia; area where neuron cell bodies cluster together
Functions
Serves as a communication link between CNS and the rest of the body
somatic division
Somatic motor (voluntary)
Conducts impulses from the CNS to the skeletal muscle
autonomic division
Visceral motor (involuntary)
conduct impulses from the CNS to cardiac, and smooth muscle and glands
Neuron

Multipolar Neuron
Anatomy of the nervous system
nerve components
axon
the longer part of the nerve fiber
endoneurium
connective layer that wraps around a nerve fiber
perineurium
connective tissue layer that wraps around a nerve fascicle
epineurium
fibrous sheath that wraps around the whole nerve
Fascicle
a bundle of axons
Myelin sheath
segmented sheath that wraps around a nerve fiber for electrical insulation
glial cells
Schwann cells
produce myelin sheath in the PNS
Oligodendrocytes
