What is the difference between the effective refractory period and the relative refractory period?
-The effective refractory period is the time in which the cell is incapable of responding to a second stimulus between the phases of 0-3.5, while the relative refractory period is the time in which the cell is making preparations to receive stimulus between phase 3.5-4.
What causes absolute refractory period?
The absolute refractory period coincides with pretty much the entire duration of the action potential. It is caused by the inactivation in neurons.
Absolute refractory period relative refractory period?
In absolute refractory period, none of channels are reconfigured, so that second active potential cannot be generated no matter how large the stimulus current is applied to the neuron. In contrast, in relative refractory period, some but not all of channels are reconfigured, another action potential can be generated but only by a greater stimulus current thatn that originally needed.
What is the channel responsible for absolute refractory period?
Na+ channels influx (phase 0) then L-type Ca 2+ (slow calcium channels) to maintain the plateau (phase 2) then the first half of phase 3 - where voltage-gated and the delayed (iK1) k+ channels are starting to open and the Ca++ are starting to close. Phases 0-3.5 this is the absolute refractory period - PERIOD
What is the period of a 0.85m long pendulum?
The period of a 0.85 meter long pendulum is 1.79 seconds.
How long doe a refractory period last?
Refractory period has several meanings. Assuming you are referring to the sexual meaning, that can vary a lot, from minutes to hours.
How long is absolute refractory period for skeletal muscles?
The refractory period generally lasts one millisecond
Is the neuron ready to fire during the refractory period?
Refractory period
2 Define refractory period and differentiate between absolute and relative refractory periods?
refractory period is the interval between action potential , the absolute refractory period is the period in which second action potential can not be initiated but in relative refractory period the second action potential can be initiated by the more strong stimulus.
A period after an initial stimulus when a neuron is not sensitive to another stimulus is the?
After the generation and propagation of an action potential along a neuron, the cell becomes depolarized to the point where there is no potential for further signaling until the cell re-polarizes through the action of ion pumps. This very brief period is called the refractory state.
When a muscle is unable to respond to stimuli temporarily which period is it in?
The refractory period is when a muscle is temporary unable to respond to stimuli refractory period
Define the period of repolarization when only a strong stimulus will elicit an action potential?
Relative refractory period
What period is a muscle is unable to respond to stimuli temporarily?
The refractory period is when a muscle is temporary unable to respond to stimuli refractory period
Which term referes to the period whereby no impulse can be generated even with intense stimulation?
Absolute refactory period
What is the cause of the relative refractory period?
The Refractory period is when a second action potential is possible, but unlikely; second action potential only if the stimulus is sufficiently strong. The refractory period helps to prevent backflow of Sodium.
What is the difference between the effective refractory period and the relative refractory period?
-The effective refractory period is the time in which the cell is incapable of responding to a second stimulus between the phases of 0-3.5, while the relative refractory period is the time in which the cell is making preparations to receive stimulus between phase 3.5-4.
When do you use relative refractory period?
The relative refractory period is the time during which the generation of an action potential is impossible no matter the strength of the stimulus
