The prime muscle differs depending on the degree of abduction. From 1 to 20 degrees it is the supraspinatus muscle, from 20 to 90 degrees it is the deltoid and from 90 degree and above the action is done by that rotate the scapula (trapezius and serratus anterior).
Trapezius and Levator Scapulae
The deltoid is the prime mover in shoulder abduction. It's two antagonists are the pectoralis major and the latissimus dorsi.
In the canine: the gluteal muscles (superficial, middle, deep).
the supraspinatus ...I think Deltoid muscle(acromial part)
Prime mover is the bicep and the antagonist is the tricep.
Do you mean flexion and (abd)uction?? If so, the prime mover would be the deltoid muscle with many smaller muscles assisting. If you are in fact meaning flexion and adduction, the prime mover would be the pectoralis major and the latissimus dorsi with many smaller muscles assisting.
Gluteus medius is prime mover.Other abductors are:Gluteus MinimusTensor Fascia Latae (TFL)Sartorius
The latissimus dorsi is the muscle responsible for moving the arm posterior or backwards.
Movement>prime mover. Abduction>deltoid. Adduction>gravity. Flexion>pectoralis major(sternal part). Extension>teres major. Medial rotation>pectoralis major(sternal). Lateral rotation>infraspinatus.
No, I have not experienced an abduction that specifically targeted my shoulder.
abduction of the shoulder- crucifix on the rings in gymnastics adduction of the shoulder- second half of a star jump?
The prime mover for shoulder internal rotation is the subscapularis muscle, which is one of the four muscles that make up the rotator cuff. It originates on the subscapular fossa of the scapula and inserts on the lesser tubercle of the humerus. Contraction of the subscapularis muscle causes internal rotation of the shoulder joint.
