The suprascapular artery (or transverse scapular artery) is a branch of the thyrocervical trunk.

It arises from the thyrocervical trunk and passes upward, in front of the vertebral artery and longus colli muscle.

The suprascapular artery branches off from the thyrocervical trunk, which in turn arises from the first part of the subclavian artery.

The inferior thyroid artery runs superiorly from the thyrocervical trunk to the inferior portion of the thyroid gland.

The usual branches of the subclavian on both sides of the body are the vertebral artery, the internal thoracic artery, the thyrocervical trunk, the costocervical trunk and the dorsal scapular artery.

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.

The transverse cervical artery (transverse artery of neck or transversa colli artery) is an artery in the neck and a branch of the thyrocervical trunk, running at a higher level than the suprascapular artery.

The thyroid is supplied with arterial blood from the superior thyroid artery, a branch of the external carotid artery, and the inferior thyroid artery, a branch of the thyrocervical trunk, and sometimes by the thyroid ima artery, branching directly from the subclavian artery.
