Rhomboid muscles

The rhomboid muscles consist of two separate pairs of superficial back muscles - rhomboid minor muscle and rhomboid major muscle. Together with the trapezius muscle, levator scapulae muscle and latissimus dorsi muscle, both rhomboids connect the upper limb to the trunk. The rhomboid muscles are located in the upper back, and they stretch between the cervical and thoracic vertebrae and scapula. They provide upper limb movements, participate in maintaining the upper body posture and contribute to the stabilization of the scapula and shoulder girdle. There are some variations in the anatomy of rhomboid muscles, and sometimes both rhomboids are fused into a single muscle.
