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 muscle agonists antagonists and assisters are involved in shoulder extension and flexion?
The muscles located in the shoulder and move the arm are: the deltoid, teres major, and rotator cuff muscles. The deltoid muscle is like three muscles in one: the anterior fibers flex the shoulder, the lateral fibers abduct the arm, and the posterior fibers extend the shoulder. The rotator cuff muscles are the supraspinatus , infraspinatus , teres minor, and subscapularis . They can be remembered with the mnemonic SITS. The primary function of the rotator cuff muscles is holding the head of the humerus in the glenoid cavity. They act more to assist the other muscles.
What muscles involved in shoulder joint adduction act as fixators?
The muscles that perform adduction to the shoulder include the pectoralis major, lattissimus dors, but these are the primary movers. The fixators that do adduction are the subscapularis and teres major.
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
The pectoralis major and deltoid muscles act synergistically to?
The pectoralis major and deltoid muscles are both abductors, therefore they act synergistically to pull the arms inward toward the mid-line (in this case the chest) of the body.
Which muscle acts as antogonist to the trapezius?
The trapezium muscles in your upper shoulder area are strong, but also act up because of the tasks that are placed upon them. That task could be called an antagonist.
Do muscle act on surrounding fat?
no muscle not act on surrounding fat. muscle act on moving. fat accquired from laziness. laziness=muscle not acting. Studies have shown that muscle do in fact act upon its surrounding fat. Muscle that has been developed allow a 12% increase for the surrounding fat to become muscle! Muscle act as an inner furnace for your body and burns your fat as well throughout the day! That's why people with more muscle need to eat more often.
What act did curb presidential military muscle?
War Powers Act Yoloswag
What is the antagonist of the teres major muscle?
Teres Major originates on the dorsal aspect of the inferior angle of the scapula and inserts on the medial lip of the intertubercular groove of the humerus. Teres Major can internally rotate and adduct the arm.
What act curbing presidential military muscle?
The War Powers Resolution was the act that was intended to curb presidential military muscle. Nixon vetoed the act, however, the veto was overridden by the U. S. Senate.
What do muscles that act on the shoulder originate?
Most originate on the Scapula (the Shoulder Girdle), not all though. The Pectoralis Major & Minor and the Latissimus Dorsi do not.
