MICROANATOMY

Detailed explanation-1: -Your autonomic nervous system breaks down into three divisions, each with its own job: Sympathetic nervous system: This system activates body processes that help you in times of need, especially times of stress or danger. This system is responsible for your body’s “fight-or-flight” response.

Detailed explanation-2: -The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.

Detailed explanation-3: -The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system. The somatic nervous system consists of nerves that go to the skin and muscles and is involved in conscious activities.

Detailed explanation-4: -The Sympathetic Division of the ANS is responsible for mobilizing the body in response to situations that are threatening or otherwise exciting. It activates functions needed to energize what is called the fight-or-flight response, the preparation to attack or run from an enemy.
