What is normal CBF
What is autoregulation and how does it happen
What are the changes in autoregulation in chronic hypertension
What factors affect ICP
Seizure activity

What is the CSF route through the ventricles
lateral ventricle

Its absorbed in the arachnoid villi
What is the monroe kelly doctrine

if one increases then the other must decrease as the skull is a fixed box
What are the theories regarding autoregulation
myogenic
local metabolites
Which nerve fibres have the fastest conduction
a alpha fibres
100m/s
Which nerve fibres have the slowest conduction rate
