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 … WebBy definition, the refractory period is the amount of time during which a cell is incapable of repeating another action potential after one has been initiated. There are two types of refractory periods: The absolute refractory period , which is the interval of time during which a second action potential cannot be initiated, no matter how large ...
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 … See more To understand the refractory period, you need to know about how electrical messages are transferred from nerve cell to nerve cell or from nerve cell to other tissue cells. See more With the above information, it is now possible to understand the difference between the absolute refractory period and relative refractory period. In terms of an action potential, refractory periods prevent the … See more The word refractory means stubborn or resistant to a process. In terms of action potentials and neurons, this is self-explanatory. A … See more In heart pacemaker cells that act very similarly to neurons, another type of refractory period exists – the effective refractory period or … See more WebThe relative refractory period is the interval of time during which a second action potential can be initiated, but initiation will require a greater stimulus than before. Refractory periods are caused by the inactivation gate of the Na + channel. Once inactivated, the Na + channel cannot respond to another stimulus until the gates are re-set.
WebRefractory period. When a neuron is in a hyperpolarized state it is also in a 2-millisecond refractory period. During the 2 second refractory period after hyper-polarization, the membrane potential overshoots past the resting potential and then returns to its resting membrane potential once again thereafter.
