Information about Dorsal Scapular Artery

Artery:
The scapular and circumflex arteries.
Muscles connecting the upper extremity to the vertebral column. (Dorsal scapular artery not labeled, but region of muscles supplied is visible.)

The dorsal scapular artery (or descending scapular artery[1]) is a blood vessel which supplies the latissimus dorsi, levator scapulae, rhomboids, and trapezius.

It most frequently arises from the subclavian artery (the second or third part)[1], but a quarter of the time it arises from the transverse cervical artery.[3] In that case, the artery is also known as the deep branch of the transverse cervical artery.

It passes beneath the levator scapulae to the superior angle of the scapula, and then descends under the rhomboid muscles along the vertebral border of the scapula as far as the inferior angle.

The dorsal scapular nerve arises from the brachial plexus, usually from the plexus root (anterior ramus) of C5.

It provides motor innervation to the rhomboid muscles, which pull the scapula towards the spine and levator scapulae muscle, which elevates the scapula.
