Diaphragmatic surface; Inferior surface - Facies diaphragmatica; Facies inferior


The diaphragmatic surface (inferior surface), directed downward and slightly backward, is formed by the ventricles, and rests upon the central tendon and a small part of the left muscular portion of the diaphragm. It is separated from the base by the posterior part of the coronary sulcus, and is traversed obliquely by the posterior longitudinal sulcus.
