[9], Blood supply of the deltoid: The posterior circumflex humeral artery and the deltoid branch of the thoracoacromial artery are the vascular sources for the deltoid. [11], Innervation of the deltoid: The neural supply of the deltoid is via the axillary nerve (C5, C6) from the posterior cord of the brachial plexus.[11]. A synergist that makes the insertion site more stable is called a fixator. [5][20], Neuromuscular exercises typically focus on movement quality, as guided by the supervising physical therapists.

The opposite, or antagonistic, action of bringing your arm toward the side of your body is called adduction. The abduction of the arm begins with the arm in a position parallel to the torso and hand in an inferior position, continues with the movement of the arm to a position perpendicular to the torso, and ends with the movement of the arm so that the humerus is raised above the shoulder joint and points straight upward. illiopsoas Elite athletes or powerlifters may perform the Valsalva maneuver during the bench press. The primary agonist muscles used during a shoulder press are the anterior deltoids and the triceps brachii, while the primary antagonist muscles are the latissimus dorsi and the biceps brachii.

Champaign, IL: Human Kinetics; 2000:3751. Reeducation of the rotator cuff muscles (working in rotations at various angles of elevation, scaption movements and functional activities). Therefore, it has a more superior line of pull which cannot offset the line of force emitted from the deltoid muscle. What is a Muscle Force Couple?. Upon activation, the muscle pulls the insertion toward the origin. Anatomy & Physiology by Lindsay M.
