AP PSYCHOLOGY

Detailed explanation-1: -Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances. Glia are also essential to nervous system function, but they work mostly by supporting the neurons.

Detailed explanation-2: -Neurons (also called neurones or nerve cells) are the fundamental units of the brain and nervous system, the cells responsible for receiving sensory input from the external world, for sending motor commands to our muscles, and for transforming and relaying the electrical signals at every step in between.

Detailed explanation-3: -Neurons are information messengers. They use electrical impulses and chemical signals to transmit information between different areas of the brain, and between the brain and the rest of the nervous system.

Detailed explanation-4: -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.

Detailed explanation-5: -Neurons carry messages from the brain via the spinal cord. The neurons that carry these messages to the muscles are called motor neurons. Each motor neuron ending sits very close to a muscle fibre.
