It er covered, in front, by huden, the superficial fascia, the Platysma, the supraclavicular nerves, og the deep cervical fascia. The external vena jugularis crosses its medial part og receives the transverse scapular, transverse cervical, og anterior vena jugulariss, which frequently form a plexus in front of arterien. Bak the veins, the nerve to the Subclavius descends in front of arterien. The terminal part of arterien lies bak kravebenet og the Subclavius og er crossed by the transverse scapular blodårer. The vena subclavia er in front of og at a slightly lower level than arterien. Bak, it lies on the lowest trunk of the brachial plexus, which intervenes mellom it og the Scalenus medius. Above og to its lateral side er the upper trunks of the brachial plexus og the Omohyoideus. Below, it rests on the upper surface of the first rib.
