ANATOMY

Detailed explanation-1: -A part of the peripheral nervous system called the autonomic nervous system controls many of the body processes you almost never need to think about, like breathing, digestion, sweating, and shivering. The autonomic nervous system has two parts: the sympathetic nervous system and the parasympathetic nervous system.

Detailed explanation-2: -The brain stem is in charge of all the functions your body needs to stay alive, like breathing air, digesting food, and circulating blood. Part of the brain stem’s job is to control your involuntary muscles-the ones that work automatically, without you even thinking about it.

Detailed explanation-3: -Answer and Explanation: The organs that are not controlled by the autonomic nervous system are the skeletal muscles. Unlike the organs of the autonomic nervous system, such as the heart, kidneys, and liver, the skeletal muscles are under conscious control.

Detailed explanation-4: -The autonomic nervous system controls all “automatic” body functions, such as breathing, heart rate, blood pressure, sweating, mouth-watering (salivating), and the movement of food through the intestines (peristalsis).

Detailed explanation-5: -The brain stem sits beneath your cerebrum in front of your cerebellum. It connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate and blood pressure.
