Description:
Cardiac Conduction System and Coronaries. This 3D model shows the cardiac conduction system and the coronaries, in the canonical configuration of the coronaries. The coronaries have been given colours. Corresponding faint transparent colour shadings indicate the supplied cardiac areas by each coronary. It can be observed that the dorsally lying AV node is supplied by a branch from the right coronary, whilst the bundle branches that lie centrally in the septum are in the left coronary's supply area.
fThe conduction system of the heart consists of cardiac muscle cells and conducting fibers (not nervous tissue) that are specialized for initiating impulses and conducting them rapidly through the heart. They initiate the normal cardiac cycle and coordinate the contractions of cardiac chambers. The conducting system provides the heart its automatic rhythmic beat. For the heart to pump efficiently and the systemic and pumonary circulations to operate in synchrony, the events in the cardiac cycle must be coordinated.
