Definition of action potential in English: action potentialnoun Physiology The change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell. Example sentencesExamples - As a nerve impulse, or action potential, reaches the end of a presynaptic axon, molecules of neurotransmitter are released into the synaptic space.
- The latter is known to be due to the fact that hypocalcemia prolongs the duration of phase two of the action potential of cardiac muscle.
- During transduction, potassium floods into the hair cell, depolarising the cell and triggering an action potential in the associated cochlear neurones.
- An outstanding example of the success of this approach is the experimental analysis of the resting potential and the action potential (nerve impulse) by Hodgkin and colleagues in the late 1940s.
- Each neuron connects with other neurons or target cells at synapses, sites at which the propagation of an action potential induces neurotransmitter release.
