Autorhythmicity refers to the ability of certain cells, particularly in the heart, to generate rhythmic electrical impulses independently of external stimuli. This property is primarily exhibited by pacemaker cells in the sinoatrial (SA) node, which control the heart's rhythmic contractions. Autorhythmicity ensures a consistent heartbeat, allowing the heart to pump blood effectively without needing direct neural input for each contraction.
