AP PSYCHOLOGY

Detailed explanation-1: -Your spinal nerves send electrical signals between your brain, spinal cord and the rest of your body. These electrical nerve signals help you feel sensations (sensory nerve) and move your body (motor nerves).

Detailed explanation-2: -The brain stem connects the brain with the spinal cord. It controls hunger and thirst and some of the most basic body functions, such as body temperature, blood pressure, and breathing.

Detailed explanation-3: -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-4: -The brainstem is the lower extension of the brain, located in front of the cerebellum and connected to the spinal cord. It consists of three structures: the midbrain, pons and medulla oblongata. It serves as a relay station, passing messages back and forth between various parts of the body and the cerebral cortex.
