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: Rotator Cuff. The main muscles that are used in conjunction with the glenohumeral joint are the group of muscles known as the rotator cuff. The rotator cuff is made up of four muscles, the supraspinatus, subscapularis, infraspinatus, and teres minor.All four of these muscles connect the scapula to the humerus.ne main purpose of the rotator cuff muscles is to pull the humerus into the scapula such that the two bones are fitted tightly against one another. Thus rotator cuff muscles are important for stabilizing the glenohumeral joint.
