Levator scapulae runs nearly vertically in the back and side of the neck.
- Raises the medial side of the scapula, hence causing medial rotation of the lower pole.
- Transverse process of the axis
- Transverse process of the atlas
- Posterior tubercle of the transverse process of C3
- Posterior tubercle of the transverse process of C4
- Upper medial border of the scapula, between the superior angle and the triangular area at the medial side of the scapular spine
- The number of vertebral attachments is variable
- May send slips of muscle to the occipital bone, mastoid process, trapezius, scalene, serratus anterior, or first or second ribs.
- May have several parts or bellies
- May unite in part or completely with serratus anterior
- A separate muscle levator claviculae may coexist
