$SA$ node

Vedclass · Answer

(D) The heart is myogenic,meaning it can generate its own electrical impulses. The $SA$ node (Sinoatrial node) is known as the pacemaker of the heart because it has the highest rate of spontaneous depolarization and generates action potentials without any external stimulus. While the $AV$ node and Purkinje fibers also possess autorhythmicity,the $SA$ node initiates the impulse that sets the rhythm for the entire heart.
