ANATOMY

Detailed explanation-1: -Central Nervous System: The Brain and Spinal Cord.

Detailed explanation-2: -Together, the brain and spinal cord form the central nervous system. This complex system is part of everything we do. It controls the things we choose to do-like walk and talk-and the things our body does automatically-like breathe and digest food.

Detailed explanation-3: -It controls things like thought, movement, and emotion, as well as breathing, heart rate, hormones, and body temperature. CNS is referred to as “central” because it combines information from the entire body and coordinates activity across the whole organism.

Detailed explanation-4: -Your autonomic nervous system includes a network of nerves that extend throughout your head and body. Some of those nerves extend directly out from your brain, while others extend out from your spinal cord, which relays signals from your brain into those nerves.
