Thyrocervical trunk

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 other structures in the neck region.

The thyrocervical trunk arises near the origin of the subclavian artery, ascends vertically and soon divides into four branches:

The thyrocervical trunk provides blood supply to the viscera of the neck, brachial plexus, and muscles of the neck.
