Witryna5 mar 2024 · A nerve impulse is a sudden reversal of the electrical charge across the membrane of a resting neuron. The reversal of charge is called an action potential. It begins when the neuron receives a chemical signal from another cell. The signal …
Witryna28 gru 2024 · Definition. The refractory period of a neuron is the time in which a nerve cell is unable to fire an action potential (nerve impulse). Two subsets exist in terms of neurons: absolute refractory period and relative refractory period. The first describes the inability to send a new impulse when sodium channels preceding this impulse are … WitrynaNerve Impulse is defined as a wave of electrical chemical changes across the neuron …
