Nerve impulses are electrical signals that transmit information throughout the nervous system. They allow for communication between neurons and enable various physiological processes in the body.
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.
