4 Notable Areas w/out BBB

Pineal
Area postrema (sense toxins for emesis)
Median Eminence and Neurohypophysis (Post Pit) to release/sense hormones

2 Dividers of Dura Mater

Falx Cerebri - vertical
Tentorium Cerebelli - horizontal

8

Arachnoid Granulations

Extensions of arachnoid mater into dural sinus that filter/drain CSF into blood

9

Path Through Ventricles

Lateral ventricles through interventricular foramen of Monro to 3rd Ventricle through Cerebral Aqueduct (of Sylvius) to 4th Ventricle to Central Canal of Spinal Cord

10

2/3 Foramen of 4th Ventricle

Midline foramen of Magendie and 2 Lateral foramina of Luschka

3 Hematomas Comparisons (source, descrip, radiologic appearance)

Epidural - middle meningeal a./lucid interval/smooth surface
Subdural - small cerebral v.s/slow onset/ragged edge
Subarachnoid - cerebral a.s (aneurysm)/worst headache of my life/can't really see as well
