The thyrocervical trunk (also called trunk of thyrocervical artery, latin: truncus thyreocervicalis) is a short wide branch of the subclavian artery that supplies the thyroid gland and the neck region.
The thyrocervical trunk arises near the origin of the subclavian artery, ascends vertically and divides into four branches :
- inferior thyroid artery,
- suprascapular artery,
- ascending cervical artery,
- transverse cervical artery.
The thyrocervical trunk provides blood supply to the viscera of the neck, brachial plexus, and muscles of the neck.
