action potential

n.
A momentary change in electrical potential on the surface of a cell, especially of a nerve or muscle cell, that occurs when it is stimulated, resulting in the transmission of an electrical impulse.

action potential

n
(Physiology) a localized change in electrical potential, from about –70 mV to +30 mV and back again, that occurs across a nerve fibre during transmission of a nerve impulse

ac′tion poten`tial


n.
the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals. Compare nerve impulse.

action potential

- A brief electrical signal transmitted along a nerve or muscle fiber following stimulation.
