Detailed explanation-1: -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.

Detailed explanation-2: -Although most of the autonomic nervous system responses are involuntary, they can integrate with the somatic nervous system, which is responsible for the voluntary movements. For example, in the case of defecation, there is an interplay between voluntary and involuntary movements.

Detailed explanation-3: -Because the autonomic nervous system regulates involuntary or automatic functions, it is called the involuntary nervous system.

Detailed explanation-4: -Both the central and peripheral nervous systems have voluntary and involuntary parts. However, whereas these two parts are closely linked in the central nervous system, they are usually separate in other areas of the body. The involuntary nervous system is made up of three parts: The sympathetic nervous system.

Detailed explanation-5: -Then there are somatic motor fibers, which only innervate skeletal muscle and control voluntary actions of the body, like putting the coffee cup back on the table until it cools down. On the flip side, the autonomic nervous system controls the involuntary activities within the body.
