Anatomical terms of neuroanatomy

The tela choroidea (or tela chorioidea) is a region of meningeal pia mater that adheres to the underlying ependyma, and gives rise to the choroid plexus in each of the brain’s four ventricles.[1][2] Tela is Latin for woven and is used to describe a web-like membrane or layer.[3] The tela choroidea is a very thin part of the loose connective tissue of pia mater overlying and closely adhering to the ependyma.[2][1] It has a rich blood supply. The ependyma and vascular pia mater – the tela choroidea, form regions of minute projections known as a choroid plexus that projects into each ventricle.[1][2] The choroid plexus produces most of the cerebrospinal fluid of the central nervous system that circulates through the ventricles of the brain, the central canal of the spinal cord, and the subarachnoid space.[4][2] The tela choroidea in the ventricles forms from different parts of the roof plate in the development of the embryo.[2][1]
