A member asked:
If your internal carotid arteries are normal wouldnt the external ones be normal as well?
A doctor has provided 1 answer
Probably: The common carotid artery divides into internal and external branches. The internal carotid is much more important as it is the major blood supply to the brain. When atherosclerosis develops it often starts at the branch point (the "bifurcation.")
