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.
Ligaments and tendons are soft collagenous tissues. Ligaments connect bone to bone and tendons connect muscles to bone. Ligaments and tendons play a significant role in musculoskeletal biomechanics. They represent an important area of orthopaedic treatment for which many challenges for repair remain.igaments connect bone to bone and tendons connect muscles to bone.
