Where does the rhomboid major insert?

• A. Lateral border of the scapula
• B. Superior angle of the scapula
• C. Inferior border of the scapula
• D. Medial border of the scapula from the spine to the inferior angle

Answer: (D)

The rhomboid major attaches along the medial border of the scapula, running from the spine of the scapula down to the inferior angle. This placement lets the muscle pull the scapula toward the vertebral column (retraction) and help downwardly rotate the shoulder blade, which fits the muscle’s action. The medial border from the spine to the inferior angle is the hallmark insertion for the rhomboid major, distinguishing it from the minor (which attaches near the spine of the scapula) and from insertions at other borders.
