To keep the humeral head centered within the glenoidal cavity the rotator cuff muscles must be a) located posteriorly b) located distally c) located anteriorly d) located in the same plane.

The correct answer is option d, that is, located in the same plane.

Explanation:

The rotator cuff refers to the group of four different muscles and their tendons that offer stability and strength at the time of motion of the shoulder complex. The muscles originate from the scapula and associates with the humerus head, producing a cuff surrounding the glenohumeral joint.  

The rotator cuff muscles are utilized in different extremity motions comprising abduction, flexion, external rotation, and internal rotation. As a group, these muscles are accountable for steadying the shoulder joint, by offering fine-tuning motions of the humerus head within the glenoid fossa.  

They assist in maintaining the humerus head inside the small glenoid fossa of the scapula in order to enhance the range of motion in the glenohumeral joint and prevent mechanical obstruction. In order to retain the humeral head aligned within the glenoidal cavity, the rotator cuff muscles must be aligned in a similar plane.  

the correct answer should be false
