Redigerer Arteria vertebralis (avsnitt)

=== Andre del ===
Andre del runs upward through the [[foramina]] in the [[transverse processes]] of the upper six cervical vertebræ, and is surrounded by branches from the inferior cervical sympathetic ganglion and by a plexus of veins which unite to form the vertebral vein at the lower part of the neck. 

It is situated in front of the trunks of the cervical nerves, and pursues an almost vertical course as far as the [[transverse process of the atlas]], above which it runs upward and lateralward to the foramen in the transverse process of the atlas.
