the body
the pns can be divided into the autonomic and somatic nervous system. the autonomic nervous system can be divided into the parasympathetic, sympathetic, and enteric nervous system. the sympathetic nervous system regulates the “fight or flight” responses. the parasympathetic nervous system regulates the “rest and digest” responses. the enteric nervous system innervates the viscera (gastrointestinal tract, pancreas, and gall bladder). the somatic nervous system consists of peripheral nerve fibers that send sensory information to the central nervous system and motor nerve fibers that project to skeletal muscle. the somatic nervous system engages in voluntary reactions, and the autonomic nervous system engages in involuntary reactions.
body reactivity
the peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system. in the somatic nervous system, the cranial nerves are part of the pns with the exception of the optic nerve (cranial nerve ii), along with the retina. the second cranial nerve is not a true peripheral nerve but a tract of the diencephalon. cranial nerve ganglia originated in the cns. however, the remaining ten cranial nerve axons extend beyond the brain and are therefore considered part of the pns. the autonomic nervous system exerts involuntary control over smooth muscle and glands. the connection between cns and organs allows the system to be in two different functional states: sympathetic and parasympathetic.
