Compared to the tricuspid valve's three flaps, how many cusps does the mitral (bicuspid) valve normally have?

1. The right atrioventricular valve, or tricuspid valve, typically consists of three flaps or leaflets. 2. The left atrioventricular valve is called the mitral valve, also known as the bicuspid valve. 3. As its alternate name suggests, this valve structurally consists of two cusps, the anterior medial and posterior medial cusps. 4. Three, four, or one cusp do not match the two cusps specifically described for the mitral valve. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 19 "The Cardiovascular System: The Heart", section 19.1, p. 837_
