Nerve Impulse Definition
(1) The movement of a nerve fiber’s action potential in response to a stimulation (such as touch, pain, heat or cold).
(2) The transmission of a coded signal from a nerve cell to an effector, such as a muscle, gland, or another nerve cell, across the membrane of a nerve cell.
A Nerve impulse is the reaction to a stimulus of a coded signal from a nerve cell to an effector (muscle cell, gland cell, or another nerve cell).
It’s how a nerve cell communicates with another nerve cell.
This signal travels through the nerve cell’s axon, carrying a message instructing an effector to act.
A nerve impulse, for example, travels through the axon of a nerve cell to urge a muscle cell to contract at a neuromuscular junction.
The word originated from nerve + impulse.
