Question 4

absorption of CSF is mainly through the __________

Answer 4

arachnoid villi

Question 5

T or F

elevations in systemic arterial pressure cause little or no increase of pressure at the capillary level

Answer 5

TRUE

because of cerebrovascular autoregulation, hence, LITTLE increase in CSF pressure
