Rotator cuff muscles are likely to most likely to protect against shoulder dislocation.
Step-by-step explanation:
The rotator cuff muscles are a group of muscles -infraspinatus, supraspinatus, subscapularis, teres minor. The prime function of these muscles is to stabilize the shoulder joint – glenohumeral joint (a ball and socket joint) and to control its movements. The muscle forms a cuff around the humeral head and rotates the joint.
The rotator cuff muscles;
- Stabilize the glenohumeral joint
- Holds and protects the humeral head over the glenoid cavity
- Prevents any upsliding movement of the humeral head
- Facilitates shoulder movements like abduction, internal and external rotation
Any injury or weakness of the rotator cuff muscles will destabilize the shoulder joint and make it prone for dislocations.
