definition: specialized cells that are found in the lateral ventricle, 3rd ventricle, and 4th ventricle that produces CSF in the ventricles

functions:

- 500 ml/day is produced
- returned to the venous system
CSF

arachnoid villi
What artery provides blood to the choroid plexus?
anterior choroidal artery
definition: enlarged ventricles due to too much CSF that can lead to an enlarged head, developmental delayed, ocular problems, and unsteady gait
hydrocephalus
