Q.
Refractory period comes in between
AMUAMU 1997
Solution:
: Refractory period is the interval during which muscle fibres fails to respond to a second stimulus. The refractory period is divided into an absolute refractory period, corresponding to the period from the time the firing level is reached until repolarization is about one-third complete, and a relative refractory period, lasting from this point to the start of after-depolarization.
