AP PSYCHOLOGY

Detailed explanation-1: -Neurons are the cells that pass chemical and electrical signals along the pathways in the brain. They come in many shapes and sizes. Their shapes and connections help them carry out specialized functions, such as storing memories or controlling muscles.

Detailed explanation-2: -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-3: -Neurons communicate via both electrical signals and chemical signals. 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-4: -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.
