Detailed explanation-1: -The human brain is the command center for the human nervous system. It receives input from the sensory organs and sends output to the muscles. The human brain has the same basic structure as other mammal brains, but is larger in relation to body size than any other brains.

Detailed explanation-2: -Think of the brain as a central computer that controls all the body’s functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back.

Detailed explanation-3: -A relatively small number of these galanin neurons form a parenting command center-the medial preoptic area (MPOA)-in the hypothalamus, a brain structure responsible for controlling everything from appetite to sex drive.

Detailed explanation-4: -It is the command centre for our nervous system controlling every movement and decision we make in our lifetime-from our appetite and our heart rate to our emotions and dreams. The brain is an individual personal storage device securely holding every cherished memory.

Detailed explanation-5: -The central nervous system is made up of the brain and spinal cord: The brain controls how we think, learn, move, and feel. The spinal cord carries messages back and forth between the brain and the nerves that run throughout the body.
