Explanation:
Detailed explanation-1: -The chordae tendinae (CT) are strong, fibrous connections between the valve leaflets and the papillary muscles . These are attached to the leaflets on to the ventricular side and prevent the cusps from swinging back into the atrial cavity during systole.
Detailed explanation-2: -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).
