Aspect of the cerebrospinal fluid (CSF): clear liquid
Many diseases affect the composition of the CSF. The analysis of the CSF sampled by lumbar punction may help to diagnose:
Infectious diseases
Brain hemorrhages
Inflammatory diseases
Tumors
Acellular liquid that contains proteins and carbohydrates.
Circulation of CSF
Production of CSF by the choroid plexus
The choroid plexus produce approximately 500 ml of CSF per day. The ventricular system contains about 140 ml of CSF. This volume is completely renewed several times a day.
→ Filling of the ventricular system
Circulation inside the ventricular system and the subarachnoid space
lateral ventricles
