68. VENTRICULAR SYSTEM AND CSF CIRCULATION. CLINICAL NOTES

Question 1

How is CSF absorbed into the venous system?

Answer 1

CSF is taken up by the arachnoid villi into the venous system, where it is ultimately drained into the jugular vein.

Question 2

What is hydrocephalus?

Answer 2

Hydrocephalus occurs when there is a blockage of CSF flow, typically at the cerebral aqueduct or ventricles, leading to increased intracranial pressure and potential brain damage if not treated.

Question 3

What is communicating hydrocephalus?

Answer 3

Communicating hydrocephalus occurs when CSF can circulate but does not get absorbed normally due to failure of the arachnoid villi.

Question 4

What is non-communicating hydrocephalus?

Answer 4

Non-communicating hydrocephalus is caused by obstruction in the pathways of the CSF.
