The vertebral artery origins from the subclavian artery, moves cranially and penetrates into the “foramen magnum” to meet the cotralateral artery so to origin the basilary artery.
The length of the vertebral artery is approx. 25 cm. with a diameter between 3 and 6 mm.
In 60% of the normal population, the vertebral arteries don’t have an equivalent caliper: in 45% the left is larger and “dominant”; in 34% the two vessels are equivalent and in 21% the right is larger.The basilary artery origins only from the dominant artery…………
