NEET BIOLOGY

Detailed explanation-1: -(b) Sympathetic and parasympathetic neural system control all the visceral organs of the body. Whereas, the somatic neural system is a part of the peripheral nervous system and is not related to the regulation of visceral organs. Similarly, CNS is not concerned with it.

Detailed explanation-2: -Final answer: Functioning of visceral organs is controlled by medulla oblongata.

Detailed explanation-3: -The sympathetic system controls “fight-or-flight” responses. In other words, this system prepares the body for strenuous physical activity. The events that we would expect to occur within the body to allow this to happen do, in fact, occur. The parasympathetic system regulates “rest and digest” functions.

Detailed explanation-4: -The sympathetic and parasympathetic nervous systems mostly have opposite effects, and a balance between both leads to homeostasis. This was all about the Visceral Nervous System and its functions.

Detailed explanation-5: -The sympathetic nervous system (SNS) is a network of nerve cells running from the brain stem down the spinal cord and out into the body to contact a wide variety of organs, including the eyes, heart, lungs, stomach and intestines, joints, and skin.
