Document Summary

The nervous system: central nervous system (cns, brain, spinal cord, peripheral nervous system (pns, skeletal nervous system, sensory or afferent, motor or efferent, autonomic nervous system i. Central nervous system - the cns includes the brain and spinal cord. The spinal cord communicates with all the sensory organs and muscles, except those of the head. Peripheral nervous system - the pns includes cranial nerves and spinal nerves, which transmit sensory information from the body to the. Cns and transmit motor and other commands in the other direction, from the cns to muscles, glands, and internal organs. The skeletal portion controls the various muscles (e. g. , your leg muscles), relaying motor commands from the brain. The autonomic nervous system (ans) controls involuntary muscles (e. g. , heart and diaphragm) and many internal organs (e. g. , the viscera). The sympathetic division, which promotes the fight-or-flight response, involves high arousal/alertness, mobilizes the body for rapid energy expenditure, and inhibits digestion.
