Detailed explanation-1: -The messages carried by neurons are called nerve impulses. Nerve impulses can travel very quickly because they are electrical impulses. Neurons are usually classified based on the role they play in the body. Two main types of neurons are sensory neurons and motor neurons.

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.

Detailed explanation-3: -axon, also called nerve fibre, portion of a nerve cell (neuron) that carries nerve impulses away from the cell body.

Detailed explanation-4: -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.
