Which muscle elevates the scapula and has an important role in neck function?

• A. Levator scapula
• B. Serratus anterior
• C. Rhomboids
• D. Latissimus dorsi

Answer: (A)

Levator scapulae is the muscle that elevates the scapula. It runs from the transverse processes of the upper cervical vertebrae to the superior angle and medial edge of the scapula, so when it contracts it lifts the shoulder blade during actions like a shrug and helps tilt the scapula to support shoulder movement. Its cervical attachments also give it a role in neck function: with the scapula stabilized, it can assist in lateral flexion of the neck to the same side, and with both sides working, contribute to neck extension. The other muscles listed don’t primarily elevate the scapula—serratus anterior protracts and upwardly rotates the scapula, rhomboids retract and downwardly rotate, and latissimus dorsi, while important for arm movement, does not elevate the scapula.
