AP PSYCHOLOGY

Detailed explanation-1: -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. The messages help you move your limbs and feel sensations, such as pain.

Detailed explanation-2: -The electrical signals are action potentials, which transmit the information from one of a neuron to the other; the chemical signals are neurotransmitters, which transmit the information from one neuron to the next.

Detailed explanation-3: -Neurons send and receive electrical signals to communicate with each other in the nervous system and with other types of cells in the body, particularly muscles.

Detailed explanation-4: -Most neurons have an axon, a long thin fibre along which the electrical impulse travels. At its terminal, an axon either connects to other neurons along which the signal continues to travel, or to muscle cells or glands where it generates a response.
