What muscles adduct the arm?
The pectoralis major, teres major, lastissimus dorsi, and the carica adduct and medially, or internally, rotate the humerus.
Which structure does the radius rotate upon?
humerus
What muscles abducts the 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
What muscles are involved in lateral rotation of the humerus?
The rotator cuff muscles: Supraspinatus Infraspinatus Teres Minor Supscapularis Easily remembered as SITS.
What abducts the 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 flexor and pronator muscles originate on the?
humerus
How many muscles attach to the lesser tubercle of the humerus?
Three muscles attach to the lesser tubercle of the humerus: subscapularis, teres major, and the supraspinatus.
The extrinsic muscles of the hand orignate on the?
lateral epicondyle of the humerus
What muscles surround the humerus bone?
The bicep on the front and the tricep on the back.
What are the actions of the rotator cuff muscles in the shoulder joint?
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 extrinsic muscles of the hand originate where?
The extrensic muscles of the hand originate from the lateral epicondyle of the humerous
What bone do the muscles of the rotator cuff originate?
The rotator cuff muscles are referred to occasionally as the SITS muscles. The Supraspinatus, Infraspinatus, Teres minor and the subscapularis. The Supras. originates on the scapula and inserts on the humerus. The Infras. originates on the scapula and inserts on the humerus(greater tubercle. The Teres minor originates on the scapula and inserts on the humerus. The Subscapularis originates on the scapula and inserts on the humerus(lesser tubercle). The function of this muscle group is to stabilize the shoulder joint. Hope this helps.
