WebPreviously, this was shown to be a part of how muscle cells work. For skeletal muscles to contract, based on excitation–contraction coupling, requires input from a neuron. Both of the cells make use of the cell membrane to regulate ion movement between the extracellular fluid and cytosol. WebDec 28, 2024 · 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 inactivated.
