Vedclass · Answer

(C) The latent period is the time interval between the application of a stimulus and the start of muscle contraction.In skeletal muscle,the latent period is very short (approximately $0.01$ seconds).In cardiac muscle,the latent period is significantly longer due to the prolonged refractory period,which prevents tetanic contraction.Therefore,the statement that the latent period is minimum in cardiac muscle is incorrect.Thus,Assertion is correct,but Reason is incorrect.

$A$: Latent period is the interval between the application of an appropriate stimulus and the initiation of contraction.
$R$: Latent period is minimum in cardiac muscle fibres.
