===Septation===
===Septation===
Septation of the tubular heart begins in the atrioventricular canal. Two masses of cardiac mesenchymal tissue, known as endocardial cushions, extend towards each other and fuse. The fused endocardial cushions form the septum intermedium, which divides the common atrioventricular canal into left and right atrioventricular canals.
