Editing Subclavian artery (section)

=====Right subclavian artery=====
The first part of the right subclavian artery arises from the brachiocephalic trunk, behind the upper part of the right sternoclavicular articulation.<ref name="Vascular and Interventional Radiology-2006" /><ref name="Imaging Anatomy: Ultrasound (Second Edition)-2018">{{Citation|title=Lower Cervical Level and Supraclavicular Fossa|date=2018-01-01|url=http://www.sciencedirect.com/science/article/pii/B9780323548007500192|work=Imaging Anatomy: Ultrasound (Second Edition)|pages=124–129|editor-last=Woodward|editor-first=Paula J.|publisher=Elsevier|language=en|doi=10.1016/b978-0-323-54800-7.50019-2|isbn=978-0-323-54800-7|access-date=2021-01-05|editor2-last=Griffith|editor2-first=James F.|editor3-last=Antonio|editor3-first=Gregory E.|editor4-last=Ahuja|editor4-first=Anil T.|url-access=subscription}}</ref> It passes upward and lateralward to the medial margin of the [[scalenus anterior muscle]]. It ascends a little above the medial part of the [[clavicle]].<ref name="Barral-2011" />

It is covered, in front, by the integument, superficial fascia, the [[platysma muscle]], deep [[fascia]], the clavicular origin of the [[sternocleidomastoid muscle]], the [[sternohyoid muscle]], and the [[sternothyroid muscle]], and another layer of the [[deep fascia]]. It is crossed by the [[internal jugular vein]] and the [[vertebral vein]], by the [[vagus nerve]] and the cardiac branches of the vagus and sympathetic, and by the subclavian loop of the [[sympathetic trunk]] which forms a ring around the vessel. The [[anterior jugular vein]] is directed laterally in front of the artery, but is separated from it by the sternohyoid muscle and the sternothyroid muscle. Below and behind the artery is the [[pleura]], which separates it from the apex of the [[lung]].<ref name="Barral-2011" /> Behind the artery is the sympathetic trunk, the [[longus colli muscle]] and the first [[thoracic vertebra]] (T1). The [[Recurrent laryngeal nerve|right recurrent laryngeal nerve]] winds around the lower and back part of the vessel.<ref name="Barral-2011" />
