Choroid plexus

Definition

The choroid plexus is a network of cells that produces cerebrospinal fluid (CSF) in the ventricles of the brain. It plays a crucial role in maintaining the environment surrounding the central nervous system.

5 Must Know Facts For Your Next Test

1. The choroid plexus is located in all four ventricles of the brain.
2. It is composed of ependymal cells, which are responsible for secreting CSF.
3. CSF produced by the choroid plexus circulates through the ventricular system and into the subarachnoid space.
4. The choroid plexus acts as a barrier, protecting the brain from potentially harmful substances in the blood.
5. Proper functioning of the choroid plexus is essential for maintaining intracranial pressure and overall neural health.
