Rotator cuff tendons insert onto which bone?

Rotator cuff tendons insert onto which bone?

• A. Scapula
• B. Humerus
• C. Clavicle
• D. Sternum

Answer: (B)

Rotator cuff tendons attach to the proximal end of the humerus, with insertions at the greater tubercle (supraspinatus, infraspinatus, and teres minor) and the lesser tubercle (subscapularis). This arrangement lets the cuff stabilize the glenohumeral joint and rotate the humerus. The scapula is where these muscles originate, while the clavicle and sternum are not tendon insertion sites for the rotator cuff.
