The vertebral artery on which side is typically larger?
left vertebral artery
What is the gender bias regarding size of the vertebral artery?
men have larger vertebral arteries than women
What is the name of the physical exam used to determine vertebral artery patency?
the vertebrobasilar artery insufficiency test
At what location will the vertebral artery from its first compensatory loop?
the atlanto-axial interspace
At what location will the vertebral artery form its second compensatory loop?
the atlanto-occipital interspace
At what segments will the vertebral artery be firmly attached to the transverse foramen?
both C1 and C2
What is the purpose of the vertebral artery loops between C2, C1, and occiput?
the increased length will accommodate the greater rotation at these locations
