Which system regulates involuntary functions of visceral and other organs?

The correct answer is the autonomous nervous system, which is more commonly referred to as the autonomic nervous system. This system is crucial for regulating involuntary functions within the body, such as heart rate, digestion, respiratory rate, pupillary response, and urination. It automatically controls these vital processes without any conscious input, allowing the body to maintain homeostasis and respond to changes in the internal and external environment effectively.

The autonomic nervous system is further divided into the sympathetic and parasympathetic systems, which often have opposing effects on the organs they influence. For example, the sympathetic system prepares the body for 'fight or flight' responses, increasing heart rate andRedirecting blood flow to the muscles. In contrast, the parasympathetic system promotes 'rest and digest' activities, slowing the heart rate and enhancing digestive processes.

Other systems mentioned do not fulfill the same role. The central nervous system primarily encompasses the brain and spinal cord, coordinating overall body functions, including voluntary movements and processing sensory information. The somatic nervous system is responsible for voluntary control over skeletal muscles, allowing conscious movements. The peripheral nervous system includes all nerves outside the central nervous system, connecting it with the limbs and organs, but does not define the involuntary regulation of
