The upper and lower fibers tend to rotate the scapula around the sternoclavicular articulation so that the acromion and inferior angles move up and the medial border moves down (upward rotation). The upper and lower fibers work in tandem with serratus anterior to upwardly rotate the scapulae, and work in opposition to the levator scapulae and ...
Costal aspect of medial margin of the scapula: Artery: Lateral thoracic artery, superior thoracic artery (upper part), thoracodorsal artery (lower part) Nerve: Long thoracic nerve (from roots of brachial plexus C5-C7) Actions: Protracts and stabilizes scapula, assists in upward rotation. Antagonist: Rhomboid major, rhomboid minor, trapezius ...
At the glenohumeral joint, movement of the humerus is performed by a combination of transverse abduction, by the posterior and lateral deltoids, [3] and external rotation, by the infraspinatus and teres minor. [4] At the scapulothoracic joint, the middle and lower fibers of the trapezius and the rhomboids contract to perform retraction of the ...
levator scapulae, the upper fibers of the trapezius Scapular depression [12] The scapula is lowered from elevation. The scapulae may be depressed so that the angle formed by the neck and shoulders is obtuse, giving the appearance of "slumped" shoulders. [citation needed] pectoralis minor, lower fibers of the trapezius, subclavius, latissimus dorsi
Shoulder shrug exercises can help to strengthen neck and shoulder muscles which in results help to reduce neck pain. The core muscle that gets activated during shoulder shrugs are trapezius. [ 7 ]
The upright row is a weight training exercise performed by holding a weight with an overhand grip and lifting it straight up to the collarbone. This is a compound exercise that involves the trapezius, the deltoids and the biceps. The narrower the grip the more the trapezius muscles are exercised, as opposed to the deltoids.
External rotation of the shoulder with the arm at a 90-degree angle is an additional exercise done to increase control and range of motion of the Infraspinatus and Teres minor muscles. Various active exercises are done for an additional 3–6 weeks as progress is based on an individual case-by-case basis. [9]
This is a compound exercise that also involves the triceps and the front deltoids, also recruits the upper and lower back muscles, and traps. The bench press is the king of all upper body exercises and is one of the most popular chest exercises in the world. It is the final exercise in 'The big 3'.
