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 ...
Levator scapulae forms part of the latter group together with rhomboid major, rhomboid minor, serratus anterior, and trapezius. The trapezius evolved separately, but the other three muscles in this group evolved from the first eight or ten ribs and the transverse processes of the cervical vertebrae (homologous to the ribs).
The large rhombus-shaped muscle, located under the trapezius muscle, in the upper part of the thoracic region of the back, and the small muscle, in the same way, participate in the movement of the scapula. [4] Their functions are the following: [1] [2] [3] Drawing scapula superomedially; Supporting scapula; Rotating glenoid cavity inferiorly
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
elevation of the scapula at the shoulders (e.g. shrugging shoulders) include: Levator scapulae muscle; Rhomboid major muscle and Rhomboid minor muscle; Trapezius muscle; elevation of the ribs. Pectoralis minor muscle; Scalene muscles; mandible. Medial pterygoid muscle; upper lip. Levator labii superioris; upper lip and wing of nose
The original technique was first described by Eden [4] in 1924 and verified by Lange in the 1950s. [5] [6] The rhomboid major and rhomboid minor were transferred laterally from the medial border of the scapula to the infraspinatous fossa, and the levator scapulae was transferred laterally to the spine of the scapula, near the acromion.

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 ...
