Rhomboid major muscle
Skeletal muscle in the human back / From Wikipedia, the free encyclopedia
The rhomboid major is a skeletal muscle of the back that connects the scapula with the vertebrae of the spinal column.[1] It originates from the spinous processes of the thoracic vertebrae T2–T5 and supraspinous ligament; it inserts onto the lower portion of the medial border of the scapula.[2] It acts together with the rhomboid minor to keep the scapula pressed against thoracic wall and to retract the scapula toward the vertebral column.[1]

As the word rhomboid suggests, the rhomboid major is diamond-shaped. The major in its name indicates that it is the larger of the two rhomboids.[citation needed]
