AP PSYCHOLOGY

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. Billions of neurons work together to create a communication network. Different neurons have different jobs.

Detailed explanation-2: -A synapse releases chemical signals, which are called neurotransmitters. These signals travel to another neuron to create a new electrical wave in that cell. Figure 1: Communication between two nerve cells. The structure of a nerve cell, and the site of cell-to-cell communication (the “synapse”).

Detailed explanation-3: -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. It contains threadlike nerves that branch out to every organ and body part.

Detailed explanation-4: -Your nervous system uses specialized cells called neurons to send signals, or messages, all over your body. These electrical signals travel between your brain, skin, organs, glands and muscles.

Detailed explanation-5: -The nerve cell releases chemical signals, called neurotransmitters, which travel across the synapse to another neuron to create a new electrical wave in that cell.
