Tela choroidea
Tela Choroidea
Tela Choroidea (pronunciation: te-la ko-ro-i-de-a) is a double layer of pia mater that is covered by a layer of ependymal cells. It is part of the ventricular system in the brain and contributes to the production of cerebrospinal fluid (CSF).
Etymology
The term 'Tela Choroidea' is derived from Latin, where 'tela' means 'web' and 'choroidea' refers to the 'choroid', a term used in anatomy to describe structures resembling the vascular layer of the eye.
Function
The Tela Choroidea is involved in the production of cerebrospinal fluid, which is crucial for the protection and metabolic regulation of the brain. It forms the choroid plexus in the third and lateral ventricles, which are the main sites of CSF production.
