Autonomic Nervous System
The autonomic nervous system (ANS) is a network of nerves that control and regulate bodily functions such as heart rate, blood pressure, digestion, respiration, and more. It is a vital component of the nervous system, and is responsible for maintaining the body’s homeostatic balance by responding to changes in the environment. This system helps the body adapt to changes in temperatures, hormones, levels of stress, and other external and internal factors. The two main divisions of the ANS are the sympathetic nervous system, which prepares the body for action, and the parasympathetic nervous system, which conserves energy and restores the body to a calm state. Diseases of the ANS can include hypertension, hypotension, anxiety, diabetes, and stroke, among others, making it an important area of study for medical professionals.
