Cusps of heart valves
Base of ventricles exposed by removal of the atria. (Valves visible on top of heart.)
Aorta laid open to show the semilunar valves. (Note that captions don't align with current terminology.)

The cusps of the heart valves serve to seal the heart valves when closed. There are normally three cusps for each valve except the mitral valve (hence its alternate name, "bicuspid valve".) Grays Fig. ... The mitral valve, also known as the bicuspid valve, is a valve in the heart that lies between the left atrium (LA) and the left ventricle (LV). ...

"Nodules" are located at the tip of the valve, to form a tighter seal.

Semilunar valves

Cusps of heart valves

• pulmonary valve^[1]
  • "right cusp"
  • "left cusp"
  • "anterior cusp"

• aortic valve^[2]. (Note that one is absent in the condition bicuspid aortic valve.)
  • "right cusp"
  • "left cusp"
  • "posterior cusp" (or "noncoronary cusp")

The pulmonary valve (or pulmonic valve) is the semilunar valve of the heart that lies between the right ventricle and the pulmonary artery and has three cusps. ... The aortic valve is one of the valves of the heart. ... A bicuspid aortic valve is a heart condition that is usually due to a congenital deformity. ...

Atrioventricular valves

• tricuspid valve
  • "anterior cusp" (or "infundibular cusp")
  • "posterior cusp" (or "marginal cusp")
  • "septal cusp" (or "medial cusp")

• mitral valve
  • "anterior cusp"
  • "posterior cusp"

In anatomy, the heart valves are valves in the heart that prevent blood from flowing the wrong way. ... The mitral valve, also known as the bicuspid valve, is a valve in the heart that lies between the left atrium (LA) and the left ventricle (LV). ...
