CNS
|
CONSISTS OF TH EBRAIN AN SPINAL CORD WHICH PRIMARILY INTERPRET INCOMING SENSORY INFORMATION AND ISSUE INSTRUCTIONS BASED ON PAST EXPERIENCE
|
PNS
|
CONSISTS OF THE CRANIAL AND SPINAL NERVES, GANGLIA, AND SENSORY RECEPTORS
HAS TWO MAJOR SUBDIVISIONS: SENSORY AND MOTOR
|
SENSORY PORTION OF PNS
|
CONSISTS OF NERVE FIBERS THAT CONDUCT IMPULSES TOWARD THE CNS
|
MOTOR PORTION OF PNS
|
CONTAINS NERVE FIBERS THAT CONDUCT IMPULSES AWAY FROM THE CNS
CONSISTS OF SOMATIC DIVISION AND AUTONOMIC NERVOUS SYSTEM
|
SOMATIC DIVISION OF MOTOR PORTION
|
"VOLUNTARY SYSTEM"
CONTROLS THE SKELETAL MUSCLES
|
AUTONOMIC NERVOUS SYSTEM OF MOTOR PORTION
|
"INVOLUNTARY SYSTEM"
CONTROLS SMOOTH AND CARDIAC MUSCLES AND GLANDS
SYMPATHETIC AND PARASYMPATHETIC BRANCHES PLAY MAJOR ROLE IN MAINTAINING HOMEOSTASIS
