The primary muscles that internally rotate the humerus include the subscapularis, pectoralis major, and teres major. Additionally, the anterior fibers of the deltoid and the latissimus dorsi also contribute to this action. These muscles work together to rotate the arm towards the body, playing a crucial role in various upper body movements.
The pectoralis major, teres major, lastissimus dorsi, and the carica adduct and medially, or internally, rotate the humerus.
humerus
The major muscle that abducts the humerus is the Deltoid. (all muscles move in conjuction, there may be more muscles that contribute to the abduction of the humerus) pectoralis major and latissimus dorsi
The rotator cuff muscles: Supraspinatus Infraspinatus Teres Minor Supscapularis Easily remembered as SITS.
The major muscle that abducts the humerus is the Deltoid. (all muscles move in conjuction, there may be more muscles that contribute to the abduction of the humerus) pectoralis major and latissimus dorsi
humerus
Three muscles attach to the lesser tubercle of the humerus: subscapularis, teres major, and the supraspinatus.
lateral epicondyle of the humerus
The rotator cuff muscles in the shoulder joint help to stabilize and rotate the arm bone (humerus) within the shoulder socket. They also assist in lifting and rotating the arm, as well as providing support and control during arm movements.
The bicep on the front and the tricep on the back.
The extrensic muscles of the hand originate from the lateral epicondyle of the humerous
