Solution :-

The sino-atrial (SA) node is a specialized bundle of neurons that have the ability to generate action potential without any external stimuli. This action potential is responsible for initiating and maintaining the rhythmic contraction of the heart. Due to this ability, the SA Node is called the pacemaker.
