CSF, ventricles and the blood brain barrier

HideShow resource information
What are the functions of the CSF?
1. Buoyancy, 2. Chemical stability, 3. Clearing waste, 4. Protection, 5. Prevention of brain ischemia
1 of 8
How does the CSF give a buoyancy effect?
It suspends the brain which allows it to maintain its density without being impaired by its own weight
2 of 8
How does the CSF provide protection?
It protects the brain tissue from injury when jolted or hit.
3 of 8
How does the CSF prevent brain ischemia?
Decreasing the amount of CSF in the skull decrease intracranial pressure
4 of 8
How does the CSF clear waste?
CSF has found to be important in the glymphatic system
5 of 8
How does the CSF provide chemical stability?
CSF flows throughout the inner ventricular system in the brain and is absorbed back into the bloodstream, rinsing the metabolic waste from the CNS through the blood brain barrier.
6 of 8
What are the ventricles in the brain?
A communicating network of cavities filled with CSF
7 of 8
What are the functions of the blood brain barrier?
1.Protects the brain from foreign substances, 2. Protects the brain from neurotransmitters and hormones, 3. Maintains a constant environment for the brain
