Levator scapulae muscle

Levator Scapulae Muscle

The Levator Scapulae Muscle is a skeletal muscle situated at the back and side of the neck. As the name suggests, it functions to elevate the scapula, which is the bone that connects the humerus (arm bone) with the clavicle (collar bone).

Anatomy

The Levator Scapulae originates from the transverse processes of the first four cervical vertebrae and inserts into the medial border of the scapula. It is innervated by the dorsal scapular nerve, a branch of the brachial plexus.

Function

The primary function of the Levator Scapulae is to elevate the scapula. Additionally, when the neck is fixed, it can draw the scapula medially and upwards. When the scapula is fixed, it bends the neck sideways and rotates it to the same side.

Clinical Significance

The Levator Scapulae can often be a source of neck pain and stiffness, especially in individuals who perform repetitive tasks involving the shoulder or have poor posture. Physical therapy, including stretching and strengthening exercises, can often help alleviate symptoms related to Levator Scapulae dysfunction.
