The costocervical trunk arises from the upper and back part of the second part of subclavian artery, ... This branch is not constant, but is more commonly found on ...
The thyrocervical trunk is a branch of the subclavian artery. [1] It arises from the first portion of this vessel, between the origin of the subclavian artery and the inner border of the anterior scalene muscle. It is located distally to the vertebral artery and proximally to the costocervical trunk. It is short and wide artery. [2]
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, which may branch off the transverse cervical artery, which is a branch of the thyrocervical trunk.
The 1st and 2nd posterior intercostal arteries arise from the supreme intercostal artery, a branch of the costocervical trunk of the subclavian artery. The SICA descends vertically. It passes lateral to the cervicothoracic ganglion. It passes in between the pleural cupula, and anterior border of the neck of rib I.
The deep portion runs down between the semispinales capitis and colli, and anastomoses with the vertebral and with the a. profunda cervicalis, a branch of the costocervical trunk. The anastomosis between these vessels assists in establishing the collateral circulation after ligature of the common carotid or subclavian artery.

A fatal virus has been discovered in shrews in Alabama, sparking concerns about potential contagion to humans. The Camp Hill virus was discovered by researchers at The University of Queensland.
It arises, in most cases, from the costocervical trunk, and is analogous to the posterior branch of an aortic intercostal artery: occasionally it is a separate branch from the subclavian artery.
