Witryna6 kwi 2024 · The conduction system consists of pacemaker cells that generate spontaneous action potentials, and then deliver those impulses throughout the heart. … WitrynaIn order for the heart to do its work (pumping blood throughout the body), it needs a sort of spark plug or electrical impulse to generate a heartbeat. Normally this electrical impulse begins in the upper right chamber of the heart (in the right atrium) in a place called the sino-atrial (SA) node. The SA node is the natural pacemaker of the heart.

The cardiac conduction system (CCS) (also called the electrical conduction system of the heart) transmits the signals generated by the sinoatrial node – the heart's pacemaker, to cause the heart muscle to contract, and pump blood through the body's circulatory system. The pacemaking signal travels through the right atrium to the atrioventricular node, along the bundle of His, and through the bundle branches to Purkinje fibers in the walls of the ventricles. The Purkinje fibers transmit the si… WitrynaThe order of meninges starting at the skull is dura mater, arachnoid mater, pia mater A person had a stroke in an association area. ...
