THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Tiny white collagenic cords called the chordae tendineae (literally, heart strings) anchor the cusps to the ventricular walls.

Detailed explanation-2: -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. The chordae tendineae, along with papillary muscle hold the flaps, or cusps, of each valve in place.

Detailed explanation-3: -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).

Detailed explanation-4: -The chordae tendinae are thin strands of connective tissue that anchor the leaflets of each AV valve so that they cannot open into the atrium (thus allowing backflow of blood into the atrium).
