the valve at the entrance to the pulmonary trunk from the right ventricle; it consists of semilunar cusps (valvules), which are usually arranged in the adult in right anterior, left anterior, and posterior positions; however, they are named in accordance with their embryonic derivation; thus the posteriorly located cusp is designated as the left cusp, the right anteriorly located cusp is designated the right cusp, and the left anteriorly positioned cusp is called the anterior cusp whereas a tricuspid valve is the valve closing the orifice between the right atrium and right ventricle of the heart; its three cusps are called anterior, posterior, and septal.
