Detailed explanation-1: -An axon is a long single fiber that transmits messages from the cell body to the dendrites of other neurons or to other body tissues, such as muscles.

Detailed explanation-2: -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-3: -Answer and Explanation: An action potential (nerve impulse) is an electrical signal that travels down the axon of a neuron, resulting in the release of neurotransmitters into the synapse.

Detailed explanation-4: -(A) At the synapse, the electrical signal within the neuron is translated into the release of a chemical signal called neurotransmitter. Ions flowing into the axon terminal are the signal for vesicles containing neurotransmitter to fuse with the cell membrane to release neurotransmitter.
