Document Summary

The somatic nervous system is a set of nerves that conveys information into and out of the central nervous system. The autonomic nervous system is a set of nerves that carries involuntary and automatic commands that control blood vessels, body organs, and glands. Set of nerves that prepares the body for action in threatening situations. Helps the body return to a normal resting state. Simple pathways in the nervous system that rapidly generate muscle contractions. The pns communicates with the cns through nerves that conduct sensory information into the brain, carry commands out of the brain. The brain sends commands for voluntary movement through the spinal cord to motor neurons. Damage to the spinal cord severs the connection from the brain to the sensory and motor neurons. The spinal cord is divided into four main sections, each of which controls different parts of the body. Damage to higher parts of the spinal cord usually results in greater impairment.
