The coracobrachialis originates from the same tendon as the short head of the biceps and inserts onto the inner humerus. Conjointly as agonist and antagonist couplings, they allow for the gross motor movements of the upper quadrant. Appropriate strengthening of the shoulder dynamic stabilizer muscles and adequate neuromuscular control-patterns is crucial during rehabilitation as well as the prevention of shoulder injuries. It is also important to note that muscle activation varies depending if the muscle is performing an eccentric muscle action or a concentric muscle contraction, as well as the technique selected by the lifter (i.e., wide grip versus narrow grip). 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. Elite athletes or powerlifters may perform the Valsalva maneuver during the bench press. popliteus, gastrocnemius, gracilis, sartorius. Both antagonist and agonist muscles are used for stabilization. pectoralis major When it contracts, it pulls the humerus toward the side of the body, as in the action of a pullup. Active: Joint motion due to muscle contraction (done by the patient). Teres major function depends on rhomboids activity as scapular retractormuscles that stabilize the scapula on the thoracic wall during adduction and extension of the GH joint to downward rotate the scapula, and without sufficient stability teres major will upward rotate instead of downward rotation.
