Choroid plexus

Last revised by Dr Joel Hng on 25 Sep 2022

The choroid plexus is located within the cerebral ventricles and is made of choroidal epithelial cells (type of ependymal cell), loose connective tissue (tela choroidea), and permeable capillaries. It produces cerebrospinal fluid

The choroid plexuses also form the blood-CSF barrier alongside arachnoid and arachnoid villi 2.
