________ refers to the unique ability of heart cells to generate their own action potentials.
spontaneous rythmicity
The term that refers to the unique ability of heart cells to generate their own action potentials is called automaticity. Automaticity is the ability of certain cells, such as cardiac pacemaker cells, to spontaneously generate electrical impulses without external stimulation. In the heart, automaticity is crucial for maintaining normal cardiac rhythm and coordinating the contraction of heart muscles that enable it to pump blood to the body efficiently. This is why the pacemaker cells of the heart, found principally in the sinoatrial node, are often referred to as the body’s “natural pacemaker.”
