Talk:Posterior communicating artery

Please
Please someone put in where it supplies - I think it's the midbrain but am not a reliable authority on this!

This could also be usefully done for the other arteries of the circle of Willis.

Thanks!

Fetal origin of the posterior communicating artery
This section talks about the "PCA" originating from the posterior communicating artery. The title of the section suggests that it was included here under the assumption that PCA stands for posterior communicating artery. That would mean that the posterior communicating artery originates from itself. I am (obviously) not a doctor, but on the basis of the illustration and the notion that arteries ought to grow from the heart end toward the target tissue end and not the other way around, it would seem that what the original source meant by the abbreviation PCA is posterior cerebral artery instead. Can someone who is an expert check this out?--Hieronymus Illinensis (talk) 17:58, 17 October 2009 (UTC)
