Which cells produce CSF?

The ependymal cells in the choroid plexus produce CSF (cerebrospinal fluid).

CSF Production Explained

The production of cerebrospinal fluid (CSF) is a critical function within the central nervous system. Here's a breakdown:

• Location: CSF is primarily produced in the choroid plexus, which are networks of blood vessels located within the ventricles of the brain. According to reference [3], CSF production occurs in the choroid plexus of the lateral ventricles.

• Cells Involved: The key cells responsible for CSF production are specialized ependymal cells. These cells line the ventricles and actively transport substances from the blood into the CSF.

Process of CSF Production

1. Filtration: Blood plasma is filtered across the capillaries of the choroid plexus.

2. Transport: Ependymal cells actively transport ions, nutrients, and other molecules from the filtered plasma into the ventricular space.

3. Secretion: Ependymal cells secrete various substances into the CSF, contributing to its unique composition.

4. Circulation: The produced CSF circulates through the ventricles, around the brain and spinal cord, before being reabsorbed into the bloodstream, as mentioned in reference [3].
