Which muscle inserts at the medial scapula, root of spine?

Which muscle inserts at the medial scapula, root of spine?

• A. Rhomboid major
• B. Supraspinatus
• C. Rhomboid minor
• D. Deltoid

Answer: (C)

Focus on where the muscles attach to the scapula. The rhomboid group retracts and downwardly rotates the scapula. The rhomboid minor attaches to the medial border of the scapula at the level of the spine—the root of the spine—so its insertion is right there. The rhomboid major, by contrast, attaches along the medial border from the spine down to the inferior angle, farther from the spine. So, the insertion at the medial scapula near the root of the spine corresponds to the rhomboid minor.
