From which vertebral levels does levator scapulae originate?

From which vertebral levels does levator scapulae originate?

• A. Transverse processes of C5-C7
• B. Transverse processes of C7-C9
• C. Transverse processes of C2-C5
• D. Transverse processes of C1-C4

Answer: (D)

Levator scapulae starts from the upper cervical region, specifically from the transverse processes of the first four cervical vertebrae. This means its origin is from C1 through C4, often described with the posterior tubercles of those transverse processes. From there, it runs to the superior angle and medial border of the scapula to elevate the scapula. The other proposed ranges (lower cervical levels) don’t match where this muscle originates, so the correct origin is the transverse processes of C1–C4.
