MEDICAL PHYSIOLOGY

Detailed explanation-1: -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-2: -The involuntary nervous system (vegetative or autonomic nervous system) regulates the processes in the body that we cannot consciously influence. It is constantly active, regulating things such as breathing, heart beat and metabolic processes.

Detailed explanation-3: -Parasympathetic nervous system: This part of the autonomic nervous system helps maintain normal body functions and conserves physical resources.

Detailed explanation-4: -The autonomic nervous system controls involuntary muscle movement. These muscles are generally associated with the viscera or internal organs that exhibit regular, slow contractions and involuntary actions. For example, the heart is an involuntary muscle.
