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.
Muscles are able to move bones by pulling on these tendons. This large tendon called the rotator cuff connects the humerus with the scapula (shoulder blade) and helps raise and rotate the arm. As the arm is raised, the rotator cuff also keeps the humerus tightly in the socket (glenoid) of the scapula.his wear and tear can lead to weakening of the rotator cuff tendons, through a condition know as impingement. The rotator cuff tendons are also subject to degeneration as we age. An injury to these tendons can result in a weak painful, shoulder â due to tearing of the rotator cuff tendons.
