Which muscle contributes to the "rotator cuff"?DeltoidLatissimus dorsiPectoralis MinorSupraspinatusTeres major

Problem Breakdown

The question is asking to identify which muscle is a component of the rotator cuff among the options provided.

Relevant Concepts

The rotator cuff is a group of four muscles and their associated tendons that act to stabilize the shoulder. The primary muscles included in the rotator cuff are:

1. Supraspinatus
2. Infraspinatus
3. Teres Minor
4. Subscapularis

Analysis and Detail

From the options given:

1. Deltoid - This muscle is primarily responsible for shoulder abduction and is not part of the rotator cuff.
2. Latissimus Dorsi - While this muscle contributes to shoulder movements, it is not part of the rotator cuff.
3. Pectoralis Minor - This muscle helps in movements of the scapula but is not involved with the rotator cuff.
4. Supraspinatus - This is one of the primary muscles of the rotator cuff and is responsible for abduction of the arm.
5. Teres Major - This muscle helps in shoulder adduction and medial rotation but is also not a part of the rotator cuff.

Verify and Summarize

Among the options, the only muscle that contributes to the rotator cuff is the Supraspinatus. The other options listed do not belong to the rotator cuff group of muscles.

Final Answer

Supraspinatus is the muscle that contributes to the rotator cuff.
