Levator Scapulae originates from which vertebral levels?

Levator Scapulae originates from which vertebral levels?

• A. Transverse processes C1-C4
• B. Spinous processes C5-T1
• C. Ribs 1-2
• D. Clavicle and first rib

Answer: (A)

Levator scapulae starts from the transverse processes of the first four cervical vertebrae (C1–C4). From there, the fibers travel downward and laterally to insert on the medial border of the scapula, near the superior angle. This arrangement explains its primary job: elevating the scapula. It isn’t coming from the spinous processes, ribs, or clavicle, which belong to other muscles. The upper-neck origin also fits with its innervation (the dorsal scapular nerve, mainly C5, with some C3–C4 contributions), tying its location to both shoulder movement and neck proprioception.
