e. All of these are correct.
The shoulder joint( also known as the glenohumeral joint) is a ball and socket joint that is formed between the scapula and humerus. It is one of the most mobile joints, permitting a wide range of movements.
There are different structures that play a key role in the stability of the shoulder joint.
Rotator cuff muscles are a group of such muscles that are involved in stabilizing the shoulder joint. They originate from the scapula and insert in the humerus. They also allow internal and external rotation of the arm by facilitating abduction, lateral rotation, and medial rotation. They stabilize the shoulder joint by compressing the humeral head against the glenoid cavity.
Hence, Option a is correct.
