The large rhomboid muscle is located in the upper part of the back and is covered by the trapezius muscle; it originates from the spinous processes of the 1st-4th thoracic vertebra and is inserted at the vertebral margin of the scapula below the spine.
It has the same function as the small rhomboid muscle: it makes the scapula adhere closely to the chest, elevates it, rotates it internally and gives it. If particularly weak it can lead to the detachment of the shoulder blades from the rib cage (winged shoulder blades).
It is innervated by the dorsal nerve of the scapula (C4-C5).
