Occlusion of the vertebrobasilar blood supply affects medulla, cerebellum, pons, midbrain, thalamus and occipital cortex in the brain.
Vertebral arteries branch off from the subclavian arteries and then pass through the costotransverse foramina c6 to c2 cervical vertebrae. They enter our skulls via the foramen magnum and merge to form the basilar artery at the pontomedullary junction. At the base of the brain the carotid and basilar systems join to form the circle of Willis (named of Thomas Willis 1621-1675). This tends to allow adequate brain perfusion despite occlusion of a main vessel.

Vertebral Artery
Altered head position can cause a slight occlusion of the artery. This forward head carriage also causes you to look up slightly (if your in a forward position, try correcting your spinal posture without altering your head position and you'll probably end up looking at the ceiling), which can cause further occlusion.
In a recent case that was missed my the clients GP he also had a flat back which was the result of a sway back posture. Once this was corrected it removed a great deal of pressure off the cervical spine.
