The transverse cervical artery
(transverse artery of neck
, transversalis colli artery
) is 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:
- - "Muscles of the Back: Spinal Accessory Nerve (CN XI) and Transverse Cervical Vessels"
- - "Branches of the first part of the subclavian artery."
