Drainage

Question Answer
What sinuses feed into the confluence of sinuses?straight, superior sagittal, and occipital
What sinuses drain out of the confluence of sinuses?transverse
What happens to the blood from the transverse sinuses?meets up with superior petrosal sinus (from cavernous sinus) to become sigmoid sinus to IJV
Give the order of CSF flow2x lateral ventricles > 3rd ventricle > cerebral aqueduct (of Sylvius) > 4th ventricle > foramena of Magendie (1 medial) and Luschka (2 lateral) > subarachoid space > > > arachnoid granulations allow flow into sinuses
What are circumventional organs?parts of brain (around 3rd and 4th ventricles) which do not have normal BBB; examples include pineal gland and pituatary
