|
a brief time when a neuron is unable to conduct an impulse

the period during which potassium and sodium ions are completely stable
|
|
|
the same as the resting potential

|
|
the short time the myelin sheath provides insulation from another impulse

Detailed explanation-1: -The refractory period is a period during which a nerve or muscle is incapable of responding to stimulation, immediately following a previous stimulation. In an absolute refractory period, there is a total inability to respond, in a relative refractory period, there is a response to very large stimuli.
Detailed explanation-2: -The refractory period of a neuron is the time in which a nerve cell is unable to fire an action potential (nerve impulse).
Detailed explanation-3: -Refractory period refers to the interval from depolarization to the recovery of excitabilty, and this refers to the repolarization of the nerve fibre.
Detailed explanation-4: -An important characteristic of the action potential is the refractory period, which is the time after initiation of an action potential when it is impossible or more difficult to generate a second action potential.
