choroid plexus is not a part of the blood brain barrier...........it lines the inside of the ventricles in the brain and produces CSF.

Blood brain barrier is the endothelial cells that are induced by the astrocyte foot processes to produce the blood brain barrier.

Well..I think I remember learning that the ependymal cells make up the choroid, which secretes CSF. Now, the ependymal cells are derived from neuroectoderm (via neuroepithelial cells), so I would say that the choroid is considered that part of the brain. But then again, I could be totally wrong. You just reminded me that I have to study for my Histology Shelf exam (most likely similar to your "mini-board". Later
