From which vertebral levels do rhomboid major and minor originate?

• A. Spinous processes T2-T6
• B. Spinous processes C7-T5
• C. Spinous processes C7-T12
• D. Transverse processes C7-T1

Answer: (B)

The muscles rhyme to contract together from the spinous processes of the vertebrae in the upper back. The rhomboid minor attaches at the spinous processes of C7 and T1, while the rhomboid major attaches from T2 through T5. If you consider both muscles, their origins span from C7 down to T5. That makes the range from C7 to T5 the correct description of their origins. The other options don’t fit: something like T2–T6 misses the C7–T1 contribution and adds a level not part of the pair; extending to T12 goes beyond where these muscles originate; and referencing the transverse processes is incorrect because their origins are on the spinous processes.
