Ependymal cells.

Aren't ependymal cells PART of the choroid plexus? The function of the ependymal cells (and thus the CP) is to create CSF and alter the ionic and chemical make up of the CSF. That's why during inflammation you have increased protein in the CSF...from dilatation of the blood vessels and increased permeability.

According to the ultimate textbook of Medicine (wikipedia):
"Within the brain's ventricles, a population of modified ependymal cells and capillaries together form a system called the choroid plexus, which produces the CSF."

This was my understanding of the CP and Ependymal cell relationship. Please tell me if I'm wrong. I have 1.5 weeks to find out haha.
