Moreover, the term sensorimotor system describes the sensory, motor, and central integration and processing components involved in maintaining joint homeostasis during bodily movements - more commonly understood to be functional joint stability. . The teres major is a small muscle that assists the latissimus dorsi in its action of adducting the shoulder. It is important to note, beginners do not need to perform an abundant amount of sets or repetitions. It originates from the sacrum, the upper rim of the pelvis, the lower part of the spine and the connective tissue of the lower back, and it inserts into the upper arm bone, or humerus. Normal Terms Agonist - the prime moving of a muscle in the movement Antagonist - the opposing muscle in the movement that opposes the actions of the agonist Synergist - muscles that act around the joint of the agonist's muscles Stabilizers - muscles that help support the joints and other structures during . brachioradialis, extensor carpi radialis longus In other words, an individual will have to use a lighter weight because this motion limits activation of the powerful sternoclavicular portion of the pectoralis muscle. They have a stabilization role during arm elevation; latissimus dorsi via its compression force to G.H joint, pectoralis major through higher going reaction force. Petoralis major Muscles are connected to bones by: Tendons In the Shoulder elbow movement lab, this muscle is the prime mover for forearm flexion of the arm at the elbow joint.
