Aschoff cells

Aschoff cells are specialized cells in the heart that play an important role in conducting the electrical impulses needed for heart contractions. They are located in the atrioventricular node - part of the conduction system of the heart, responsible for generating electrical impulses.

Aschoff cells have the ability to spontaneously depolarize and generate an action potential without external stimulus. This automation allows them to act as a pacemaker for the heart, setting the heart rate. When Aschoff cells depolarize, they transmit an electrical impulse to other cells of the conduction system, which conduct it through the myocardium of the atria and ventricles, causing them to contract.

Thus, Aschoff cells play a key role in ensuring the rhythmic functioning of the heart. Disturbances in their functioning can lead to the development of arrhythmias.
