The levator scapulae is a large, superficial muscle located on the back and side of the neck. It connects the cervical vertebrae (neck bones) to the scapula (shoulder blade).
Function and Anatomy
This muscle's primary function is to elevate the scapula. Think of shrugging your shoulders; the levator scapulae plays a significant role in that movement. However, it's not just about lifting the shoulder blade. The levator scapulae also contributes to:
- Scapular Rotation: It helps rotate the scapula, influencing the positioning of the shoulder joint.
- Head Tilting: It can assist in tilting the head to the same side as the contracting muscle.
The levator scapulae originates from the transverse processes of the upper four cervical vertebrae (C1-C4) and inserts into the medial border of the scapula, superior to the spine of the scapula.
Clinical Significance
Problems with the levator scapulae can lead to neck and shoulder pain. This can often be caused by muscle strain or overuse.
Reference: The provided reference states that the levator scapulae is "a large superficial muscle that stretches along the outside of the neck from the cervical vertebrae to the scapula. It primarily works to elevate the scapula, but is also involved in rotating the scapula and tilting the head."
