In that journey the vertebral Arteries pass through the foramen transverarium of the upper 6 cervical vertebrae. Of special note is a quote and observation by Frank Netter, M.D., anatomical illustrator of considerable note and publishing in his Netter Series. Structural displacement, especially whiplash injury and other trauma, to these osseous structures can wrought vertebral havoc in the UpC neuro-spine. All sorts of negative possibilities for quality of life and optimal longevity can unfold. UpC structural displacement can be a cause of partial disruption of full par volume of arterial flow to the basilar junction.
Hypoxia can result.
