PATHOLOGY

Detailed explanation-1: -The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions such as the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal. Hence, Autonomic nervous system controls Involuntary activities.

Detailed explanation-2: -Actions which take place without consciousness or willingness of an individual are called the involuntary action. Digestion, heart beating, sneezing, etc are few examples of involuntary actions. Both involuntary and voluntary actions are controlled by the same parts of the brain.

Detailed explanation-3: -/ɪnˈvɒləntɛri/ Involuntary describes a reflex or action done without conscious control or will-like a blink, a sneeze, a yawn, or “the giggles.” If you volunteered to do it, it’s voluntary. If you didn’t volunteer, but you find yourself doing it anyway, it’s involuntary.
