Detailed explanation-1: -Your autonomic nervous system is a network of nerves throughout your body that control unconscious processes. These are things that happen without you thinking about them, such as breathing and your heart beating.

Detailed explanation-2: -The brain is what controls all the body’s functions. The spinal cord runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part. This network of nerves relays messages back and forth from the brain to different parts of the body.

Detailed explanation-3: -Your nervous system is your body’s command center. Originating from your brain, it controls your movements, thoughts and automatic responses to the world around you. It also controls other body systems and processes, such as digestion, breathing and sexual development (puberty).

Detailed explanation-4: -These are the nervous system and the endocrine (hormone) system. These systems regulate body processes through chemical and electrical signals that pass between cells.

Detailed explanation-5: -The Neuroendocrine System It allows both internal and external changes to be monitored by the sense organs of the nervous system, the neural signals to be processed by the nervous system (with the hypothal-amus playing a major role) and converted to endocrine outputs.
