Action Potential at the SA Node Diagram: A Comprehensive Overview

Cardiovascular System anatomy-note-512-512-png-1-96x96 Tag Template - Week PRO Anatomy Note -
The sinoatrial (SA) node, as the heart’s natural pacemaker, generates electrical impulses that initiate each heartbeat, a process vividly illustrated in this diagram. This image details the prepotential, threshold, rapid depolarization, and repolarization phases, highlighting the unique absence of a resting potential and the role of sodium ion influx in driving spontaneous activity. Exploring this diagram provides a clear understanding of how the SA node sustains the heart’s rhythmic contractions.
