ANATOMY

Detailed explanation-1: -In the AV valves, leaflets are connected to the ventricular myocardium by chordae tendineae, while in the SL valves, cusps are anchored directly to the arterial roots.

Detailed explanation-2: -Papillary muscles, finger-like projections from the wall of the ventricles, connect the chordae tendineae (heartstrings) to the cusps of the atrioventricular valves. This connection prevents the valve from prolapsing under pressure.

Detailed explanation-3: -The two atrioventricular valves, the mitral valve, and the tricuspid valve, are connected to the ventricles by thin, fibrous strands of tissue called chordae tendineae.

Detailed explanation-4: -Mitral/bicuspid valve: The mitral/bicuspid valve is the AV found between the left atrium and the left ventricle. It has two cusps and allows blood to flow from the left atrium to the left ventricle while preventing any back flow.
