Thyrocervical trunk
Lua error in Module:Infobox at line 235: malformed pattern (missing ']'). The thyrocervical trunk is a branch of the subclavian artery arising from the first portion of this vessel, i.e. between the origin of the subclavian artery and the inner border of the scalenus anterior muscle. It is located distally to the vertebral artery and proximally to the costocervical trunk.
Branches
It is a short and thick vessel and it divides soon after its origin into four branches:
- inferior thyroid artery
- suprascapular artery
- ascending cervical artery
- transversalis artery colli or transverse cervical artery
The suprascapular artery and transverse cervical artery both head laterally and cross in front of (anterior to) 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.
