Levator Scapulae


Levator scapulae is a posterior Axio-appenducular muscle that connects the upper limb to the vertebral column and lies in the posterior triangle of the neck. The superior aspect of the levator scapulae is covered by sternocleidomastoid, and its inferior part by trapezius.[1]

The levator scapulae originates on the posterior tubercle of transverse process of cervical vertebrae 1 to 4.[2]


The levator scapulae inserts on to the vertebral margin of the scapula between the superior angle and the root of the spine.[3]


The superior third of the strap-like levator scapulae lies deep to the sternocleidomastoid while the inferior third is deep to the trapezius. From the transverse processes of the upper cervical vertebrae, the fibers of the levator of the scapula pass inferiorly to the superomedial border of the scapula.[1]

Nerve Supply

The levator scapulae is innervated by cervical nerve (C3-C4) and dorsal scapular nerve (C5).[4]

Blood Supply

Descending scapular artery[5]


The levator scapulae functions to elevate the scapula and tilt the glenoid cavity inferiorly by rotating the scapula downward. [6]

If the scapula is fixed, a contraction of the levator scapulae leads to the lateral flexion of the cervical vertebral column to the side and stabilizes the vertebral column during rotation.

Clinical Relevance

Forward head posture puts increased tension on the levator scapulae muscles to co-contract for cervical extension in an elongated position.[7] Increased tightness in the levator scapulae due to increased activity from a forward head posture can lead to cervicogenic headaches.


The levator scapulae length and tension can be assessed by placing the patient in supine, stabilizing the ipsilateral scapula, and contralateraly side bend and rotate the head. Also, trigger points are common in this muscle and can be palpated for in both the superior attachment and inferior attachment.


Pain or discomfort caused by the levator scapulae can be relieved by various modalities and active movements to provide relief.
