Related terms

Neurons:

These are specialized cells that transmit nerve impulses. They consist of a cell body, dendrites, and an axon.

Action Potential:

This is a brief change in electrical potential across a neuron's membrane when it is stimulated, resulting in the generation of a nerve impulse.

Synapse:

A synapse is a small gap between two neurons where communication occurs. Neurotransmitters transmit signals across this gap to facilitate the transmission of nerve impulses.
