Contraction of the supraspinatus muscle leads to abduction of the arm at the shoulder joint. and prevent downward rotatory movement created by deltoid (middle/posterior) and are a synergistic muscle with deltoid regards to glenohumeral forces to abduct the G.H joint. Antagonists play two important roles in muscle function: (1) they maintain body or limb position, such as holding the arm out or standing erect; and (2) they control rapid movement, as in shadow boxing without landing a punch or the ability to check the motion of a limb. Upper trapezius: hence the scapulothoracic movement occurs in response to the combination of the movement of AC and SC joint and the upper trapezius attaches to clavicle it has an indirect weak effect on scapular upward rotation and strong effect on scapular external rotation. teres major Retrieved September 18, 2015, from http://www.exrx.net/Kinesiology/BenchPress.html.Bianco, A., Filingeri, D., Paoli, A., & Palma, A. Privacy Notice/Your California Privacy Rights, Anatomy of Movement; Blandine Calais-Germain, Kinesiology of the Musculoskeletal System: Foundations for Rehabilitation; Donald A. Neumann. A synergist that makes the insertion site more stable is called a fixator. For example; the deltoid muscle (middle fiber in particular) acts to stabilize the humeral head against the glenoid cavity during arm elevation, while the rotator cuff muscles (specifically the subscapularis, teres minor, infraspinatus muscles) control the fine-tuning movement of the humeral head. Blood supply to the Serratus Anterior is the circumflex scapular artery. Several other muscles assist the major adductors of the shoulder.

Protein and Weight Loss: How Much Protein Do You Need to Eat Per Day? Movement and its agonist (top) and antagonist (bottom)muscles, Anterior deltoid The lower fiber of SA has a longer moment arm to maintain this scapular upward rotation. However, because of the vast range of motion of the shoulder complex (the most mobile joint of the human body), dynamic stabilizers are crucial for a strong sense of neuromuscular control throughout all movements and activities involving the upper extremities. During reaching or functional activities that require functional forward length of your upper limb, your scapula will be protracted and upward rotated that is achieved primarily by serratus anterior ms. As the movement of the scapulothoracic occurs in response to the combination of the movement of AC and SC joint. An Imbalance of one or more of these muscles can cause biomechanical misalignments and contribute to shoulder dysfunctions such as: impingement disorders, bursitis, instabilities, scapular dyskinesia or chronic conditions associated with pathological wear and tear.
