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 .
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
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 ...
The superior angle of the scapula is thin, smooth, rounded, and inclined somewhat lateralward, and gives attachment to a few fibers of the levator scapulae muscle. [5] The inferior angle of the scapula is the lowest part of the scapula and is covered by the latissimus dorsi muscle. It moves forwards round the chest when the arm is abducted.
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 accessory nerve (CN XI) is particularly vulnerable to damage during lymph node biopsy. Damage results in an inability to shrug the shoulders or raise the arm above the head, particularly due to compromised trapezius muscle innervation.
levator scapulae, m. splenius cervicis) from lateral side. There is anastomosis with accessory nerve, hypoglossal nerve and sympathetic trunk. It is located in the neck, deep to the sternocleidomastoid muscle. [5]
Serratus anterior forms part of the latter group together with rhomboid major, rhomboid minor, levator scapulae, 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).
