Refractory period in skeletal muscle

In physiology, a refractory period is a period of time during which an organ or cell is incapable of repeating a particular action, or (more precisely) the amount of time it takes for an excitable membrane to be ready for a second stimulus once it returns to its resting state following an excitation. It most commonly refers … See more Refractoriness is the fundamental property of any object of autowave nature (especially excitable medium) not responding to stimuli, if the object stays in the specific refractory state. In common sense, refractory … See more The refractory period in cardiac physiology is related to the ion currents that, in cardiac cells as in nerve cells, flow into and out of the cell … See more The muscle action potential lasts roughly 2–4 ms and the absolute refractory period is roughly 1–3 ms, shorter than other cells. See more • Autowave • Parabolic partial differential equation • Reaction–diffusion system See more After initiation of an action potential, the refractory period is defined two ways: The absolute refractory period coincides with nearly the entire duration of the action potential. In neurons, it is caused by the inactivation of the Na channels that originally opened to … See more The refractory period in a neuron occurs after an action potential and generally lasts one millisecond. An action potential consists of three phases. Phase one is depolarization. During depolarization, voltage-gated sodium ion channels open, … See more WebBy definition, the refractory period is a period of time during which a cell is incapable of repeating an action potential. In terms of action potentials, it refers to the amount of time it takes for an excitable membrane to be ready to respond to a second stimulus once it returns to a resting state.

Muscle Contraction

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. WebThe whole principle of summation depends on the fact that the action potential duration (and its refractory period) is much shorter than the duration of the ensuing contraction. A typical action potential in a skeletal muscle lasts 2-5 msec while a contraction may last from 100 to 1000 milliseconds. 4.
