What is the muscle that pulls the scapula medially?

Which muscles flex the arm?
the anterior part of the deltoid muscle flexes and medially rotates the humerus/ the arm. to do this it is helped by muscles like coracobrachialis and pectoralis major, corachobrachialis also adduct and flex the arm at shoulder joint.
What is antagonist to the teres minor?
The teres major muscle is considered to be antagonistic to the teres minor muscle. The teres major muscle is a larger muscle located in the upper arm that works to extend, medially rotate, and adduct the arm, while the teres minor muscle is a smaller muscle that works to laterally rotate the arm.
What 4 muscles are used to prevent movement of a broken clavicle?
There are actually more than 4 muscles that should be immobilized. When you move your shoulders you move your clavicle. The muscles that causes movement at the shoulder joint should be immobilized. This includes the prime movers, as well as the assistant movers. The following muscles should be immobile. The subclavius which moves and depresses the clavicle as well as helps stabilize the pectoral girdle. The pectoralis minorabduct the scapula and rotates it downward, lowering your shoulders. The serratus anterior abducts the scapula and cause it to rotate upward, shrugging your shoulders. The trapezius stabilizes the scapula as well as move it, and helps extend head. The levator scapulae elevates the scapula and rotates it downward. The rhomboid majorelevates, adducts, rotates downward, and stabilizes the scapula. The Rhomboid minor does the same thing as the Rhomboid major. The pectoralis major adducts and medially rotates the arm at the shoulder joint; flexes arm at the clavicular head and extends the arm to the side of the trunk at the sternocostal head. The deltoid abducts the arm at the shoulder joint; flex and medially rotates the arm at shoulder joint; and extend and laterally rotates the arm at shoulder joint. The subscapularis medially rotates the arm at shoulder joint. The supraspinatus assists the deltoid muscle to abduct the arm at the should joint. The infraspinatuslaterally rotates and abducts the arm at the shoulder joint. The teres major extends the arm at the shoulder joint and assists in the adduction and medial rotation of the arm at the shoulder joint. The teres minor laterally rotates, extends, and adducts the arm at the shoulder joint. The coracobrachialis flexes and adducts the arm at the should joint.
The teres major and tere minor originate on the?
A muscle with origin from the lower third of the border of the scapula, with insertion into the medial border of the , with nerve supply from the lower subscapular nerve from the fifth and the sixth cervical nerves, and whose action adducts and extends the arm and rotates it medially.
What muscle turns the eye inferior and medially?
The superior oblique muscle turns the eye inferiorly and medially. It is innervated by the trochlear nerve.
What upper arm muscle is named for its shape often the site of injections that abducts and rotates the arm is?

Turns the eye medially?
Eye movements are accomplished by the Extraocular Muscles. The muscle that moves the eye medially is the Medial Rectus.
