ANATOMY

Detailed explanation-1: -The nervous system uses tiny cells called neurons (NEW-ronz) to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body.

Detailed explanation-2: -Your peripheral nervous system is the network of nerves that transmit (carry) signals from all over your body to your spinal cord, which is part of your central nervous system. Your central nervous system is your brain and spinal cord. It receives and interprets nerve signals from your peripheral nervous system.

Detailed explanation-3: -The nervous system uses electrical and chemical means to help all parts of the body to communicate with each other. The brain and spinal cord make up the central nervous system. Nerves everywhere else in the body are part of the peripheral nervous system.

Detailed explanation-4: -These chemicals are called neurotransmitters, and the process is called neurotransmission. The space between the axon and the dendrites is called the synapse. When neurons communicate, an electrical impulse triggers the release of neurotransmitters from the axon into the synapse.

Detailed explanation-5: -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).
