The myocardium is the muscle tissue of the heart, a muscle responsible for pumping blood through the circulatory system through contraction. It receives a part of the large volume of blood that passes through the atria and ventricles. A system of arteries and veins (coronary circulation) provides the myocardium with oxygen-rich blood and allows the return of venous or oxygen-poor blood to the right atrium. The right coronary artery and the left coronary artery are the branches of the aorta responsible for the blood supply.

The individuals appear to be normal females at birth, but during the stage of puberty, they do not develop secondary sexual characteristics, they do not menstruate, and have fibrous gonads that does not contain eggs.
