The conducting system of the heart is specialized tissue on the inner aspect of the myocardium that conducts the heart’s electrical impulses.

The vortex of the heart is situated at the apex, where the two ventricles meet each other. Here, the myocardial fibers create an arrangement that resembles a swirl or vortex.

The myocardium is the heart’s main component and serves as the contractile component. It is thinner in the atria and thicker in the ventricles. The left ventricle’s myocardium is thicker than the right ventricle’s.

The coronary sulcus is a groove that surrounds the heart, positioned where the atria meet the ventricles.

Sulcus terminalis of the heart is a vertical groove that extends along the right atrium from the front of the superior vena cava towards the front of the inferior vena cava.
