In human anatomy, the rhomboid minor is a small skeletal muscle on the back that connects the scapula with the vertebrae of the spinal column.

The rhombods contribute to maintaining the posture of the thoracic and cervical regions of the back, and contribute to the stability of the shoulder. Because of this, their clinical impact reflects to the upper body posture and shoulder mechanics.

All muscles are named based on either their bony attachments, position/location, function, fiber orientation, or in this case, the shape of the muscle. A rhomboid is a geometric shape which has four sides, but the adjacent sides are of unequal length.
