Autonomic Nervous System

Autonomic Nervous System                                                                                                                                                                                                  R.Sayan {256-Eng} Autonomic Nervous System The autonomic nervous system (ANS) is a regulatory branch of the central nervous system that helps people adapt to changes in their environment. It adjusts or modifies some functions in response to stress. The ANS helps regulate... Blood vessels' size and blood pressure The heart's electrical activity and ability to contract The bronchium's (BRON'ke-um) diameter (and thus air flow) in the lungs The ANS also regulates the movement and work of the stomach, intestine and salivary glands, the secretion of insulin and the urinary and sexual functions. The ANS acts through a balance of its two components, the sympathetic nervous system and parasympathetic nervous system. Ø   Autonomic n
