Detailed explanation-1: -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-2: -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-3: -The part of your brain that runs autonomic functions is your hypothalamus.

Detailed explanation-4: -The hypothalamus is the key brain site for central control of the autonomic nervous system, and the paraventricular nucleus is the key hypothalamic site for this control. The major pathway from the hypothalamus for autonomic control is the dorsal longitudinal fasciculus.

Detailed explanation-5: -The nervous system includes the brain, spinal cord, and a complex network of nerves. This system sends messages back and forth between the brain and the body. The brain is what controls all the body’s functions.
