Describe the formation, flow and absorption of cerebrospinal fluid
The main points expected for a pass were
• CSF is formed by ultra filtration and secretion
• CSF volumes and turnover
• Flow through the ventricles and subarachnoid spaces
• Absorption through the arachnoid villi
• Relationship between and absorption and pressure
This is not a question about intracranial pressure so no points were given for Munroe Kellie
doctrine etc, Also no points were given for the functions of CSF.
Diagrams need to have the axes labelled correctly.
