What is hydrocephalus? Correct Answer-Hydrocephalus is the excessive accumulation of CSF that increases intracranial pressure. -Blockage in flow of CSF through ventricles of brain or when cannot be absorbed by arachnoid villi. What types of substances are able to directly cross the blood-brain barrier? Correct Answer-Lipophilic substances are able to cross the blood-brain barrier directly and enter the brain. *Water crosses membrane by simple diffusion. Most nutrients cross blood brain barr...
