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 an ascending and a descending 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.
Branches
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)
Superficial branch
The superficial cervical artery is another name for the superficial branch of transverse cervical artery. It ascends beneath the anterior margin of the trapezius, distributing branches to it, and to the neighboring muscles and lymph glands in the neck, and anastomosing with the superficial branch of the descending branch of the occipital artery.
