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:

• Inferior thyroid artery
• Suprascapular artery
• Ascending cervical artery
• Transverse cervical artery

In general, branches of the thyrocervical trunk provides blood supply to the internal organs and tissue of the neck and the brachial plexus, also supplying many muscles of the neck.
