What muscle is the prime mover of the arm?
Prime mover or agonist: principal muscle that performs action. For example, biceps brachii is the prime mover, the brachialis is a synergistic muscle for that action. Synergists: act together. For example, the biceps brachii and brachialis muscles both act to flex the forearm.
What is the prime mover for shoulder adduction?
The prime movers of horizontal shoulder adduction are the deltoid (anterior head) and pectoralis major.
Which is a prime mover of the humerus?
The biceps brachii is on the anterior side of the humerus and is the prime mover (agonist) responsible for flexing the forearm. It has two origins (hence the “biceps” part of its name), both of which attach to the scapula bone.
Which muscle is the prime mover of adduction flexion and inward rotation of the humerus?
Functionally, the latissimus dorsi muscle belongs to the muscles of the scapular motion. This muscle is able to pull the inferior angle of the scapula in various directions, producing movements on the shoulder joint (internal rotation, adduction and extension of the arm).
What muscle causes abduction of the arm?
The supraspinatus muscle originates from the supraspinous fossa of the scapula, passes under the acromion, and inserts on the superior facet of the greater tubercle of the humerus. It is responsible for the initiation of arm abduction and is in control of the motion up to the first 15 degrees of abduction.
What is posterior deltoid?
Posterior deltoids: Rear delts that help move your arm backward. They connect to the flat surface of your shoulder blade. You use your rear delts if you pitch a baseball.
What is supraspinatus muscle?
Supraspinatus is the smallest of the 4 muscles which comprise the Rotator Cuff of the shoulder joint specifically in the supraspinatus fossa. It travels underneath the acromion.
Is teres minor a prime mover?
The rotator cuff muscles could be considered the fine tuners of the glenohumeral joint and shoulder girdle, whereas the latissimus dorsi, teres major, deltoid, and pectoralis muscles are the prime movers.

Which muscle is the prime mover of shoulder abduction abduction of the arm quizlet?
Medial is prime mover for shoulder abduction and shoulder horizontal abduction, located on the side of shoulder. Posterior is prime mover for shoulder horizontal abduction. Opposing muscles is Latissimus Dorsi (back muscle).
Which muscle is named for the muscle action of turning the palm posteriorly?
The pronator teres is a muscle (located mainly in the forearm) that, along with the pronator quadratus, serves to pronate the forearm (turning it so that the palm faces posteriorly when from the anatomical position).
