ANATOMY

Detailed explanation-1: -The chordae tendineae (tendinous cords), known as the heart strings, are tendon-resembling fibrous cords of connective tissue. The chordae tendineae connect the atrioventricular valves to the papillary muscles within the ventricles. Multiple chordae tendineae attach to each leaflet of each flap of the valves.

Detailed explanation-2: -Three of these papillary muscle and chordae tendineae complexes are attached to the tricuspid valve (anterior, posterior, septal), and 2 are attached to the mitral valve (anterolateral and posteromedial).

Detailed explanation-3: -Chordae tendineae: 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.

Detailed explanation-4: -The chordae tendineae connect the atrioventricular valves (tricuspid and mitral), to the papillary muscles within the ventricles. Multiple chordae tendineae attach to each leaflet or cusp of the valves.

Detailed explanation-5: -The papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (also known as the mitral and tricuspid valves) via the chordae tendineae and contract to prevent inversion or prolapse of these valves on systole (or ventricular contraction).
