The levator scapulae is a slender [1]: 910 skeletal muscle situated at the back and side of the neck. It originates from the transverse processes of the four uppermost cervical vertebrae ; it inserts onto the upper portion of the medial border of the scapula .
The levatores costarum (/ ˌ l ɛ v ə ˈ t ɔːr iː z k ə ˈ s t ɛər ə m /), twelve in number on either side, are small tendinous and fleshy bundles, which arise from the ends of the transverse processes of the seventh cervical and upper eleven thoracic vertebrae
levator scapulae: Neck/Upper Limb, Verterbral Column, Lateral, Right/left posterior tubercles of transverse processes of C1 – C4 vertebrae: superior part of medial border of scapula: dorsal scapular artery: cervical nerve (C3, C4) and dorsal scapular nerve elevates scapula, tilts glenoid cavity inferiorly by rotating scapula: serratus ...
Scapular exercises such as shoulder shrugs and shoulder retraction exercises Improve muscular control and scapular coordination Centering of humeral head Helps to facilitate adequate muscle timing and recruitment Stretching of tight muscles such as the levator scapulae, pectoralis major, subscapularis and upper trapezius muscle
The scapula may also be misplaced if a rib deep to it is not moving correctly. Often in the case of Shoulder impingement syndrome, the scapula may be anteverted such that the shoulder on the affected side appears protracted. The ribs that may cause such an anteversion of the scapula include ribs 2–8.
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
The pec minor also works in conjunction with the rhomboid muscle and levator scapulae to perform downward rotation of the scapulae. Muscles which attach to the scapulae that adduct and extend the arm include the posterior deltoid muscles , the teres major , and minor stabilizing contribution from some rotator cuff muscles ( infraspinatus and ...
While this slightly closes the angle between the clavicle and the scapula, it also widens the shoulder. [4]: 40 The scapula can be elevated and depressed from the neutral position to a total range of 10 to 12 centimetres (3.9 to 4.7 in); at its most elevated position the scapula is always tilted so that the glenoid cavity is facing superiorly.
