Summary Introduction

Introduction:

The teres major is a type of muscle present in the upper limb. It connected to the humerus and the scapula and it is referred as one of the scapulohumeral muscles. This muscle is a flatted muscle, which is thick in nature. It is located in the latissimus dorsi muscle and it helps in the medial rotation and extension of humerus. It does not attach to the rotator muscles.

Expert Solution & Answer

Answer to Problem 1TYR

Correct answer:

The teres major is the muscle which does not contribute to the rotator cuff. Therefore option b is the correct answer.

Explanation of Solution

Justify reasons for the correct statement:

Teres major is not attached to the shoulders, glenohumeral joint, so it is not a part of rotator cuff.

Option( b) is given as “teres major”.

The teres major muscle is similar as the teres minor muscle but it does not contribute with the rotator cuff.

Hence, option (b) is the correct.

Justify reasons for the incorrect statements:

Option (a) is given as, “teres minor”.

It helps to hold the head of the humerus and it is a narrow and elongated muscle of the rotator cuff. It consists of posterior circumflex humeral artery and the circumflex scapular artery. It helps to rotate the arm. Hence, it is a wrong answer.

Option (c) is given as, “subscapularis”.

It is a part of rotator cuff muscle. It is a defence factor for shoulder joint to prevent the dislocation of the humerus head. It helps in the contraction of the subscapularis and rotation of the shoulder joint. Hence, it is a wrong answer.

Option (d) is given as, “Infraspinatus”.

It is one of the four muscles of the rotator cuff. And its functions are external rotation of the shoulder joint. The infraspinatus fascia is separated the teres major and teres minor. Hence, it is a wrong answer.

Option (e) is given as, “Supraspinatus”.

It is a small muscle and it is one of the muscles of the rotator cuff. It helps to stabilize the shoulder joint. Hence, it is a wrong answer.

Hence, options (a), (c), (d) and (e) are incorrect.

Conclusion

The teres major is not a part of the rotator cuff.
