The vertebral artery: its relationship with adjoining tissues in its course intra and inter transverse processes in man.

The authors study the vertebral artery from its origin to termination, especially in its course inter and intra transverse process and show its relation to venous and nervous structures, as well as its behavior toward adjacent conjunctive tissue. They discuss the relation of the anatomy to the physiopathology of the vertebral artery and come to the conclusion that the vertebral artery is fixed to adjacent structures in the fibrous osteomuscular tunnel by means of a continuous lamina of collagen along its entire course and that there is considerable independence between the artery and the branches of these final nerves.
