Vedclass · Answer

(C) The heart is myogenic, meaning its rhythmic contraction is initiated by a specialized nodal tissue. The $SAN$ (Sino-Atrial Node) is located in the right upper corner of the right atrium. It is known as the pacemaker of the heart because it has the highest rate of depolarization and generates the action potential first, which then spreads through the heart to initiate contraction.

Which structure first generates an action potential?
