Rotator cuff (RC) (collectively the following muscles: supraspinatus, subscapularis, infraspinatus, teres minor) not only abduct the shoulder, but also plays an important role as stabilizer muscles. The glenohumeral, or shoulder, joint is a synovial joint that attaches the upper limb to the axial skeleton. Drawing-in and abdominal bracing activates the inner unit (transverse abdominis, multifidus, pelvic floor- muscles close to the spine) and global abdominal muscles (rectus abdominis, external obliques) offering greater spinal stability. Adductors (5) Were so glad this helped. During flexing of the forearm, the triceps brachii is the antagonist muscle, resisting the movement of the forearm up towards the shoulder. A muscle that crosses the lateral side of a joint results in abduction, which results in the body part moving away from the midline of the body. brachioradialis Chapter 1. The serratus anterior and trapezius muscles act as agnostics for scapular upward rotation. Lam, Jonathan; Burdoni, Bruno. extensor carpi radialis brevis J Appl Physiol. Subscapularis originates at the medial and lower two-thirds of the lateral border of the subscapular fossa. 5th. It's more active during arm elevation in abduction and has a gradual linear increase in activity with the increase of abduction angle. The primary joint actions that occur during the bench press include: Eccentric (lowering) Phase. active relocation). quadratus femoris , Fantastic article on shoulder abduction muscles! peroneus tertis, peroneus longus Teres major has the same action of latissimus dorsi of adduction, extension, internal rotation. In the contact and recovery phase, the quadriceps contract to extend the knee while the hamstrings lengthen to allow the movement.

The opposite, or antagonistic, action of bringing your arm toward the side of your body is called adduction. 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. The latissimus dorsi is the large muscle on the upper back, while the biceps brachii are the two muscles on the inner side of the upper arm. No neurological signs or symptoms from the cervical spine, throughout the upper extremities. Contributes to a joint when contracting concentrically. The anterior deltoids are the muscles that run along the front side of the shoulders, and the triceps brachii are the muscles on the outside of the upper arms. The triceps would be the antagonist muscle as it lengthens. The stretching of the rubber band creates a storage of potential energy, and upon release the rubber band flies through the air. The human back is comprised of numerous muscles that assist in the movement of the upper torso, arms, neck, and vertebral column.

Exercises such as the incline bench press and dumbbell chest press use similar movement patterns. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article). Such muscles to consider are the serratus anterior, serratus posterior, the trapezius (upper / middle / lower), the rhomboids, teres major, the levator scapulae, the latissimus dorsi and the flexibility and mobility of the thoracolumbar fascia. Scalenus Medius During a shoulder press, the anterior deltoids are primarily used during the first half of the movement, while the triceps are primarily used during the second half of the movement to reach lockout. Check out our team's award-winning youth education site @moosmosis.org [12] The main role of the rotator cuff is to control the fine-tuning (smaller) movements of the head of the humerus, within the glenoid fossa (often thought of as the accessory movements). It is an antagonist to internal rotation. During abduction of the lateral deltoid, the shoulder joint moves downward to accommodate the arm's outward movement. There are also muscles that do not pull against the skeleton for movements such asthe muscles offacial expressions. internal oblique moreover, it is a synergistic with latissimus and pectoralis major to adduct and internally rotate the shoulder as it has a function of adduction and internal rotation of the shoulder.[18]. Hello. 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.
