Detailed explanation-1: -Tiny white collagenic cords called the chordae tendineae (literally, heart strings) anchor the cusps to the ventricular walls. The chordae tendineae originate from small bundles of cardiac muscle, papillary muscles, that project from the myocardial wall.
Detailed explanation-2: -The AV valves are anchored to the wall of the ventricle by chordae tendineae (heartstrings), small tendons that prevent backflow by stopping the valve leaflets from inverting. The chordae tendineae are inelastic and attached at one end to the papillary muscles and at the other end to the valve cusps.
Detailed explanation-3: -The chordae tendineae, also known as the heartstrings, are cord like tendons that connect the papillary muscles to the tricuspid and bicuspid valves of the heart. The chordae tendineae play a role in atrial and ventrical systole.
