The thyrocervical trunk is one of the 3 branches of the first part of the subclavian artery and gives off numerous branches to supply viscera of the neck, the brachial plexus, neck muscles and the scapular anastomosis.
Ascends as a short, stout trunk before giving rise to four branches.
inferior thyroid artery is the largest and most important branch of the trunk
sends multiple small branches through the pretracheal fascia to supply the larynx, trachea, esophagus, and thyroid and parathyroid glands, as well as adjacent muscles, hence is known as the primary visceral artery of the neck.
suprascapular artery traverses inferiorly and laterally superficial to the anterior scalene muscle and phrenic nerve before crossing the third part of the subclavian artery and the cords of the brachial plexus.
it contributes many small spinal branches into the intervertebral foramina of the neck as well as giving off multiple small muscular branches to the lateral muscles of the upper neck.
transverse cervical artery is a short artery that further bifurcates into the superficial and deep branches, both which course superficially and laterally across the phrenic nerve and anterior scalene muscle; they then cross or pass through the trunks of the brachial plexus, supplying branches to their vasa nervorum. Its branches are:
the dorsal scapular artery which accompanies the dorsal scapular nerve, coursing deep to the levator scapulae and rhomboid muscles, supplying both and contributing to the scapular arterial anastomoses. It may arise directly from the third or the second part of the subclavian artery.
the inferior thyroid artery arises from the subclavian artery in 15% of the population4 it may then be known as the accessory inferior thyroid artery.
the suprascapular artery may arise directly from the third part of the subclavian artery.
the transverse cervical artery may arise directly from the second or third part of the subclavian artery.
