The surface indentation that separates the atria from the ventricles is known as the?
Lerok [7]

Atrioventricular septum is the surface indentation that separates the atria from the ventricles.

<h3>What is an atrioventricular septum? </h3>

The interatrial and interventricular septal cross the atrioventricular annular plane and merge with the septum tricuspid and anterior mitral leaflet attachment at the septal atrioventricular junction, which is a critical region of the heart.

The tricuspid and mitral valves seem cruciate on a four-chamber view when both septa are converging, earning the term crux of the heart, cardiac crux, or crux cordis.

The atrioventricular septum, a septal component dividing the atria from the left ventricle, is a distinctive anatomic characteristic of the atrioventricular junction.

Therefore, the atrioventricular septum is the indentation that separates the atria from the ventricles.
