Suprascapular artery

The suprascapular artery (from the Latin: supra " above" and scapula " shoulder blade "; Synonym: arteria transversa scapulae, English: suprascapular artery ) is an arterial vessel branch from the thyrocervical trunk of the subclavian artery.

Course

The suprascapular artery passes first through the anterior scalene muscle and the phrenic nerve and the lamina of the cervical fascia praetrachealis caudally and laterally. She is covered by the sternocleidomastoid muscle. Thereafter, the vessel crosses the brachial plexus and the subclavian artery and passes behind the clavicle and the subclavian muscle further lateral to the superior border of the scapula. In this way, the artery crosses the lower belly of the musculus omohyoideus. Here are the suprascapular artery a branch, the ramus acromialis, for Rete acromialis from, a vascular network of the shoulder height ( acromion ).

At the shoulder blade arrived, the vessel constricts the superior transverse scapular ligament, which is the artery of the same nerve, the suprascapular nerve separates into the supraspinatus fossa ( supraspinatus fossa ) a. Here you will find the artery between the bone and the supraspinatus, the supplies it with some branches.

Artery, vein and suprascapular nerve pull from there together through the notch spinoglenoidalis - an incision between the base of the scapular spine (spina scapulae ) and the scapular neck ( neck of the scapula ) - in the infraspinatus fossa ( infraspinatus fossa ). There, the suprascapular artery anastomoses with the circumflex scapular artery, a branch of the subscapular artery, and repeatedly with the arteria transversa colli.

Function

The suprascapular artery supplies the sternocleidomastoid muscle, the musculus subclavius ​​that. Musculi supraspinatus et infraspinatus, as well as parts of the clavicle, the Schultereckgelenks and the shoulder joint with arterial blood The cutaneous branches to feed parts of the skin in the upper chest and over the acromion.
