Transverse cervical artery
|Artery: Transverse cervical artery|
Superficial and deep branches from the transverse cervical artery
|Latin||Arteria transversa cervicis,
arteria transversa colli
|Supplies||The trapezius and Sternocleidomastoid muscles|
|Vein||Transverse cervical veins|
The transverse cervical artery (transverse artery of neck or transversa colli artery) is an artery in the neck and a branch of the thyrocervical trunk, running at a higher level than the suprascapular artery.
It crosses in front of the phrenic nerve and the scalene muscles, and in front of or between the divisions of the brachial plexus, and is covered by the platysma and sternocleidomastoid muscles, and crossed by the omohyoid and trapezius.
The transverse cervical artery splits into two branches, a superficial one and a deep one:
- Superficial branch (also known as the superficial cervical artery)
- Deep branch (also called the dorsal scapular artery). Descending branch in older literature. Most often, however, this artery branches directly from the subclavian artery.
The dorsal scapular artery, sometimes a branch from the transverse cervical artery
