The peripheral nervous system consists of sensory and motor neurons that connect the central nervous system to organs and other parts of the body outside the brain and spinal cord. It carries information between the body and central nervous system through 12 pairs of cranial nerves that control the head, neck, and face and 31 pairs of spinal nerves that connect to the spinal cord. The peripheral nervous system is divided into the somatic and autonomic systems, with the somatic controlling skeletal muscles voluntarily and the autonomic regulating involuntary functions through the sympathetic and parasympathetic divisions.

 All parts of the nervous system EXCEPT
THE BRAIN AND SPINAL CORD.
 Sensory and motor neurons that
connects to the Central Nervous System

between organs of the
body and the Central
Nervous System.

4.  You have 12 pairs of cranial nerves

▪controls the head, neck, face and
shoulders
 And 31 pairs of spinal nerves [mx]
▪Take impulses (messages) to and
from the spinal cord.

7.  Somatic
▪ control skeletal muscle (bones, skin that a person
can control)
▪ Voluntary control
 Autonomic
▪ control the muscles of the glands and internal
organs which we can’t control
▪ Involuntary
▪ Autonomic-automatic

8.  Sympathetic
▪ prepares body for stress {fight or flight}
▪ Norepinephrine
 Parasympathetic
▪ brings things back to normal {calms}
▪ acetylcholine
