The voltage-gated Na+ channels get deactivated, thus the sodium ions cannot diffuse into the cell and cause depolarisation and this also provides time for the membrane to prepare for its second action potential.

Is the neuron ready to fire during the refractory period?
Refractory period
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.
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
What is the brief period during which a local area of an axon's membrane resists stimulation called?
That is called the refractory period.
What is occurring when a muscle cell cannot be stimulated during the absolute refractory period?
Repolarization
Is the neuron ready to fire during the refractory period?
Refractory period
A period of unresponsiveness during a normal heartbeat is called?
refractory period.

What is the absolute refractory period?
Absolute Refractory Period:It is the interval during which a second action potential absolutely cannot be initiated, no matter how large a stimulus is applied.ORAfter repolarization there is a period during which a second action potential cannot be initiated, no matter how large a stimulus current is applied to the neuron. This is called the absolute refractory period, and it is followed by a relative refractory period, during which another action potential can be generated
What happens to a cell during the absolute refractory?
Cell responds
What is the refractory period for men?
In sexuality, the refractory period, the recovery phase after (normally male) orgasm during which it is physiologically impossible for an individual to have additional orgasms.A brief period of time following the stimulation of a nerve during which the nerve will not respond to a second stimulus.
What is the period of time during which the neuron cannot generate another action potential called?
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.
During which period can a second action potential be initiated by a larger than normal stimulus?
This the relative refractory period.
What is the brief period during which a local area of an axon's membrane resists stimulation called?
That is called the refractory period.
