Brainstem Flashcards
One of the 3 functions of the brainstem is
regualtion of vital functions of the body
The superior colliculi are part of the roof at the level of the
midbrain
CN IV, the trochlear nerve, exits the brainstem
the dorsal surface of the midbrain
Landmarks on the ventral aspect of the midbrain include
the cerebral peduncles
the optic tracts
The ______________is the core of the brainstem.
tegmentum
The reticular formation is in the ____________of the brainstem and plays an important role in __________________.
entire brainstem ; arousal and wake/sleep
Cranial nerve V exits the brainstem on the ____________surface of the _________.
ventral lateral surface of the pons
Coma causing lesions are typically located in the
thalamus
midbrain
reticular formation
Which ventrical is at the level of the diencephalon?
3rd ventrical
The pons is the
metencephalon
Cranial nerve X exits the brainstem on the ventral lateral aspect of the
medulla
The roof of the brainstem at the level of the pons is
cerebellum
Descending motor pathways, such as the pyramidal tract, and ascending sensory pathways from the body periphery pass through the brainstem .
True
The reticular activating system is involved in
Regulation of heart rate
Regulation of blood pressure
Regulation of sleep cycles and levels of arousal
