Rhomboid major originates from which spinal level?

Rhomboid major originates from which spinal level?

• A. Spinous processes T2-T5
• B. Spinous processes C7-T1
• C. Transverse processes T1-T4
• D. Lateral border of scapula

Answer: (A)

Rhomboid major has its origin on the spinous processes of the upper thoracic spine, specifically from T2 to T5. This location along the spine lets the muscle fibers run obliquely toward the medial border of the scapula, attaching from the scapular spine down to the inferior angle. This origin supports its role in retracting and elevating the scapula and helping stabilize it against the thorax. The other options don’t fit because: C7–T1 spinous processes point to the rhomboid minor, which is superior to the major; transverse processes T1–T4 would suggest a different muscle (such as the levator scapulae or others) rather than the rhomboid major; and the lateral border of the scapula is an insertion site for the rhomboids, not an origin.
