Describe the control of cerebral blood flow.
Good answers included an equation and then explored the various components of the
equation. Main points for a pass included pressure and metabolic autoregulation and the
various factors that affect cerebral vascular resistance. Graphs were a useful way to answer
this question but were generally underutilised. Several candidates wrote about the Monroe-
Kellie doctrine which was not directly relevant to the question.
