Rhomboid Minor is innervated by which nerve?

• A. Dorsal scapular nerve
• B. Lateral thoracic nerve
• C. Suprascapular nerve
• D. Axillary nerve

Answer: (A)

Rhomboid minor is one of the scapular retractors that pulls the scapula toward the spine and helps stabilize the shoulder girdle. It gets its motor supply from the dorsal scapular nerve, a branch of the C5 root. This nerve travels to the deep surface of the rhomboids and levator scapulae to provide their innervation, which is why it is the correct choice. The other nerves listed innervate different muscles: the suprascapular nerve goes to the rotator cuff muscles (supraspinatus and infraspinatus); the axillary nerve supplies deltoid and teres minor; and the lateral thoracic nerve serves chest/pectoral region muscles rather than the rhomboids.
