The Menenges
|
1 - DURA MATER - tough and protective 2 - ARACHNOID MATER - blood supply 3 - PIA MATER - layer of capilliaries stuck to brain surface |
|
|
Cerebro-Spinal Fluid (CSF)
|
- circulates in sub-arachnoid space and through ventricle system of the brain - any blockage in the circulation of CSF will cause pressure to build up - can lead to hydrocephaly - pressue should be between 3 -15 mmHg |
|
|
Blood supply to the brain:
|
- via L and R carotid arteries and Circle of Willis - hemmorage is most likely to occur where one vessel joins another (weak point) - brain does not come into contact with blood - nutrients passed from blood to CSF at CHOROID PLEXUS |
|
|
3 types of intracranial bleeds:
|
1 - blood of fluid accumulates and increases intracranial pressure (ICP) 2 - Ischemic stroke - a blood clot blocks blood flow to an area of the brain 3 - Hemmoragic stroke - vessel ruptures and causes bleeding inside/around brain tissue |
