OriginNuchal ligaments, spinous processes of the C7-to-T5 vertebrae
InsertionMedial border of the scapula
BloodDorsal scapular artery
NerveDorsal scapular nerve
ActionPulls scapulae medially, rotates scapulae, holds scapulae into thorax wall

The rhomboid muscles (), often simply called the rhomboids, are rhombus-shaped muscles associated with the scapula. There are two rhomboid muscles on each side of the upper back:

  • Rhomboid major muscle
  • Rhomboid minor muscle

The large rhombus-shaped muscle, located under the trapezius muscle, in the upper part of the thoracic region of the back, and the small muscle, in the same way, participate in the movement of the scapula. Their functions are the following:

  • Drawing scapula superomedially
  • Supporting scapula
  • Rotating glenoid cavity inferiorly Both muscles are innervated by the dorsal scapular nerve, a branch of the brachial plexus.
