| Anatomical terminology | |
The thyrocervical trunk is a short artery of the neck. It arises from the subclavian artery, then promptly divides into its branches: the inferior thyroid artery, suprascapular artery, and (sometimes) the transverse cervical artery.
Its branches explain the alternative name for this blood vessel: "truncus thyrobicervicoscapularis".[citation needed]
Structure
The thyrocervical trunk is short and thick.[citation needed]
Origin
The thyrocervical trunk is a branch of the
scalenus anterior muscle.[citation needed
]
Relations
It is located distally to the vertebral artery and proximally to the costocervical trunk.[citation needed]
Branches
The thyrocervical trunk promplty divides into its branches:[3]
- Inferior thyroid artery.
- Suprascapular artery
- Transverse cervical artery This is present in about 1/3 of cases. In the rest, the dorsal scapular and superficial cervical arteries arise separately.[4][further explanation needed]
The
scalenus anterior muscle and the phrenic nerve. The inferior thyroid artery runs superiorly from the thyrocervical trunk to the inferior portion of the thyroid gland. There is significant variation in the origin of these vessels.[5][verification needed
