B. Bridging veins
C. Choroid plexus
D. Diencephalon - -c
-Which lobe controls abstract thought? - -Frontal
-Which part of the brain regulates behaviors, such as rage?

B. Midbrain
C. Brainstem
D. Reticular activating system - -a
-For a patient receiving mannitol (Osmitrol), which intervention should you
perform? - -Insert an indwelling urinary catheter.
-Which cranial nerve is responsible for the gag reflex?
A. Cranial nerve V (trigeminal nerve)
