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.
How long is absolute refractory period for skeletal muscles?
The refractory period generally lasts one millisecond
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
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
Define the period of repolarization when only a strong stimulus will elicit an action potential?
Relative 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
Period of reploarization of the neuron during which it cannot respond to a second stimulus?
The absolute refractory period. This period occurs after the action potential has been initiated and is a result of inactivation of the sodium channels. These sodium channels would normally open up to allow sodium influx into the cell during an action potential. The absolute refractory period occurs during an ongoing action potential and is the period in which a subsequent action potential absolutely cannot be generated.This should not be confused with the relative refractory period which occurs immediately following the absolute refractory period (during membrane hyperpolarization). During this period a subsequent action potential is possible, but more difficult to attain.
