Autonomic Nervous System comes under the motor division of the peripheral nervous system. The Autonomic nervous system serves to carry the motor information from the central nervous system to the glands and involuntary muscles. It innervates endocrine glands such as adrenal medulla and trigger release of stress hormones under emergency conditions. The sympathetic division of the autonomic nervous system triggers the release of epinephrine and norepinephrine (catecholamines) under stress conditions.
