The chordae tendineae, or heart strings, are cord like structures that connect the Mitral and tricuspid valve to the papillary muscles. The functions of chordae tendineae are: 1) bring the right ventricular walls closer together during contraction. 2) pull the semilunar valves open to allow ventricular ejection.
Chordae tendineae. The chordae tendineae, as their Latin name suggests, are tendinous cords found in the right and left ventricles of the heart. These chordae tendineae connect the papillary muscles to the leaflets of the atrioventricular (AV) valves.The vernacular term for these structures is heart strings.he chordae tendineae are part of a larger complex of interacting anatomical structures that include the fibrous skeleton of the heart, the fibrous core of the AV valves, the chordae tendineae, the papillary muscles, and the complex fibrous internal structure of the papillary muscles and the ventricular wall.
