MICROANATOMY

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.

Detailed explanation-2: -The autonomic system, a complex subset of the peripheral nervous system, controls involuntary activities, such as heart rate, temperature, and the smooth muscle activity of the vascular and digestive systems.

Detailed explanation-3: -The medulla oblongata is the part of the brain stem. This is the part which is responsible for the control of involunatry function. Many important involuntary functions like the pumping of heart, heartbeat, breathing, etc are controlled by the regions in the medulla oblongata.

Detailed explanation-4: -Also known as the visceral or involuntary nervous system, the ANS functions without conscious, voluntary control. Because it innervates cardiac muscle, smooth muscle, and various endocrine and exocrine glands, this nervous system influences the activity of most tissues and organ systems in the body.
