What muscles do shoulder adduction?
Adduction is accomplished primarily by the pectoralis major, latissimus dorsi, teres major, triceps, and coracobrachialis. The deltoid and the supraspinatus, a muscle that runs along the scapula in the back, are the two main abductors of the shoulder.
What muscles do protraction?
Protraction is accomplished by the actions of the serratus anterior, pectoralis major, and pectoralis minor muscles. Retraction is accomplished by the actions of the trapezius, rhomboids, and latissimus dorsi muscles. The elevation is accomplished by the trapezius, levator scapulae, and rhomboid muscles.
What is scapular adduction?
4. Scapular Adduction – Also called scapular extension or retraction. It is a movement the opposite of abduction. Throwing the shoulder back and pinching the shoulder blades together illsutrates adduction of the shoulder girdles.
Which muscles protract the scapula?
Which muscles protract the scapula? The serratus anterior is occasionally called the “big swing muscle” or “boxer’s muscle” because it is largely responsible for the protraction of the scapula — that is, the pulling of the scapula forward and around the rib cage that occurs when someone throws a punch.
What muscle retracts the scapula?
– Function: Retracts and rotates the scapula – Origin: Spinous processes of T2 to T5 vertebrae – Insertion: Inferomedial border of the scapula – Innervation: Dorsal scapular nerve (C5)
