Yes. Deltoid (Delta like.) is the prime mover of arm. It moves shoulder joint in forward, backward and laterally. It is a continuation ofTrapeziusmuscle. It is 'not' mentioned in any anatomy books. But you can verify it. Trapezius is inserted in inner side of clavicle and spine of scapula and from outer side of the same Deltoid muscle starts.

What is the prime mover muscle of shoulder horizontal adduction?

Because shoulder horizontal adduction is performed when the arm is horizontal position (i.e., the elbow is level with shoulder) and adduction is movement toward the center of the body, shoulder horizontal adduction is performed primarily by pectoralis major and anterior deltoid, with an assist by latissimus dorsi.


What is the abductor of the upper arm?

Abduction of the arm occurs in three segments, and hence is performed by three different sets of muscles. From 0-15 degrees, the arm is abducted by the Supraspinatus muscle. From 15-90 degrees, the arm is abducted by the Deltoid muscle. From 90-180 degrees, the arm as abducted by the Trapezius muscle with help from the Serratus Anterior muscle.

Name two muscles that reverse the movement of the deltoid muscle?

FIXATORS are synergists which immobilize the origin of the prime mover so that the prime mover can act more efficiently. For example, the deltoid is the prime mover of arm abduction. The deltoid muscle originates on the scapula, which is a moveable bone. The pectoralis minor, rhomboids, and trapezius muscles attach the scapula to the axial skeleton. When the deltoid contracts to abduct the arm, these other muscles hold the scapula still and therefore act as fixators. http://people.morehead-st.edu/fs/m.mcmurr/231-L11.html this should help you. :) weesa

What are the synergistic muscles of the thigh?

Biceps and brachioradialis. The bicep is the prime mover in elbow joint movement and the brachioradialis acts as a synergistic muscle to stabilize the joint, thus aiding in the motion.
