Transverse cervical a.

The transverse cervical artery (transverse artery of neck) is an artery in the neck and a branch of the thyrocervical trunk, running at a higher level than the suprascapular artery.

It passes transversely above the inferior belly of the omohyoid muscle to the anterior margin of the trapezius, beneath which it divides into a superficial and a deep branch.

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.
