CSF Flashcards
What is the primary function of cerebrospinal fluid (CSF)?
Protection, buoyancy, chemical stability, and waste removal.
Where is CSF produced?
In the choroid plexus of the ventricles.
How does CSF circulate from the lateral ventricles to the third ventricle?
Through the interventricular foramina.
What connects the third and fourth ventricles?
The cerebral aqueduct.
Where is CSF reabsorbed into the bloodstream?
Through arachnoid granulations into the dural sinuses.
Which ventricle is located between the cerebellum and the pons?
The fourth ventricle.
What condition results from excessive accumulation of CSF in the ventricles?
Hydrocephaly
