Rhomboid Major

Musculus rhomboideus major

Upper Body BackRhomboidsPull

The rhomboid major lies deep to the trapezius and retracts the scapula toward the spine while assisting elevation and downward rotation. It is heavily recruited in rows and scapular retraction work, and strong rhomboids counteract rounded-shoulder posture by holding the shoulder blades back and down.

Actions

Scapular retraction, Scapular elevation, Scapular downward rotation

Origin

Spinous processes and supraspinous ligaments of T2-T5

Insertion

Medial border of the scapula, below the spine (inferior to the root of the spine)

Innervation

Dorsal scapular nerve (C4-C5)

Blood supply
