Strengthening Exercises for Shoulder Joint Abductors The posterior deltoid, infraspinatus, teres minor and latissimus dorsi muscles abduct the shoulder in the transverse plane -- moving your arm out away from your body when your shoulder is flexed to 90 degrees -- bringing it parallel to the floor.erform bent over lateral raises to strengthen muscles that abduct the shoulder in the transverse plane. Bend your knees slightly and bend forward at your hips until your back is almost parallel to the floor.

What Does the Anterior Deltoid Do? Shoulder Abduction. Shoulder abduction describes raising the upper arm outward from the side of the body, such as when you put your arms out to form a T-shape. This movement is accomplished through the action of your anterior and lateral deltoids along with the pectoralis major and supraspinatus muscles.he muscle consists of three fiber groups: the anterior, lateral and posterior deltoids. The anterior deltoid, also known as the front delt, connects the collarbone to the humerus, the large bone of the upper arm.

List of Upper Body Muscles The shoulders comprise four different muscles, two of which are muscle groups. The individual muscles of the shoulders are the upper trapezius and the levator scapulae, which function to elevate the scapulae, or shoulder blades.

The Extrinsic Muscles of the Shoulder The extrinsic muscles of the shoulder originate from the trunk, and attach to the bones of the shoulder – the clavicle, scapula or humerus. They are located in the back, and are also known as the superficial back muscles. The muscles are organised into two layers – a superficial layer and a deep layer.he extrinsic muscles of the shoulder originate from the trunk, and attach to the bones of the shoulder – the clavicle, scapula or humerus.

What Muscles Contract During an Abduction of the Shoulder? Rotator Cuff Muscles. The rotator cuff is a set of four muscles that serve to stabilize and rotate the shoulder, attached by strong tendons to the upper head of the humerus. During abduction, the supraspinatous and infraspinaoous muscles abduct and rotate the head of the humerus.otator Cuff Muscles.

What are the muscles in the shoulder? Shoulder Adductor Muscles? What are the muscles involved in shoulder elevation? The muscles involved in elevating the shoulder girdle (e.g. shrugging your shoulders) are the upper fibers of trapezius, levator scapulae, rhomboid major and rhomboid minor.

Muscles The biceps and the triceps are antagonistic muscles. when the biceps muscle contracts, the forearm moves up. when the triceps muscle contracts, the forearm moves down. This solves the problem. To lift the forearm, the biceps contracts and the triceps relaxes.

Kinesiology of the Shoulder and Scapula: Shoulder Horizontal Adduction (Horizontal Flexion) 1  Prime Mover: Pectoralis major. 2  Synergists: Anterior deltoid. 3  Antagonists: Posterior deltoid.  Neutralizers: Posterior deltoid, infraspinatus, and teres minor neutralize internal rotation force created by the anterior deltoid and pectoralis major.

- Abductor muscle: Any muscle used to pull a body part away from the midline of the body. For example, the abductor muscles of the legs spread the legs away from the midline and away from one another.

Arm Abduction Arm Abduction. Abduction of the arm is also called abduction of/at the shoulder. This motion actually can be divided into two motions: true abduction of the arm at the shoulder and upward rotation of the scapula. Muscles: supraspinatus (initiates abduction - first 15 degrees), deltoid (up to 90 degrees), trapezius and serratus anterior (scapular rotation, for abduction beyond 90 degrees).

Prime mover muscles? The deltoid muscle does most of the work in abducting the shoulder, although it's likely that supraspinatus muscle does the first 10-15 degrees of movement.

Shoulder Muscles: Anatomy, Support & Movement The shoulder muscles are appendicular muscles that attach to the appendicular skeleton. That is the bones of the arm and leg. The shoulder muscles serve to stabilize our pectoral girdle and move our arms. This lesson will identify and describe the main muscles associated with the shoulder.

Lifting the Arms, Part 2: Rotate and Elevate the Shoulder Blades for Fuller, Safer Movement The shoulder blade is capable of several of movements. Abduction (also called protraction) is the movement of the scapula away from the midline of the body and around toward the front. Adduction (retraction) is the movement toward the midline. Elevation is the vertical lifting of the scapula.owever, all of these movements can be enhanced by supportive movements of the scapula, and one arm movement, elevation (lifting the arm overhead), cannot be accomplished at all by movement at the gleno-humeral joint alone.

Rupture of the lower shoulder blade muscle Anatomy: Four muscles are part of the rotator cuff surrounding the shoulder joint, and controls, coordinates and assists movement of the shoulder: M infraspinatus (the lower shoulder blade muscle), M supraspinatus, M subscapularis and M teres minor. The infraspinatus muscle rotates the arm outwards. Acromion.

Pronation/Supination [Continued from above] . . . Two muscles in the forearm, the pronator teres and pronator quadratus, work together to achieve pronation by pulling on the radius bone of the forearm. The radius is specially designed to rotate at the elbow and wrist joints around the other forearm bone, the ulna.

Shoulder The muscles and joints of the shoulder allow it to move through a remarkable range of motion, making it one of the most mobile joints in the human body. The shoulder can abduct, adduct, rotate, be raised in front of and behind the torso and move through a full 360° in the sagittal plane.

- The supraspinatus muscle is one of the musculotendinous support structures called the rotator cuff that surround and enclose the shoulder. It helps to resist the inferior gravitational forces placed across the shoulder joint due to the downward pull from the weight of the upper limb.

Acromion Tuberculum majus humeri M. infraspinatus Spina scapulare M. supraspinatus SHOULDER BLADE MUSCLES FROM THE REAR Cause: When a muscle is suddenly subjected to a load in excess of the strength of the muscle, a rupture will occur in the muscle. Rupture of the infraspinatus (the lower shoulder blade muscle) is a common throwing injury (handball).
