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
