What is the primary goal of treating TBI? How is this done? Correct ans
- preventing secondary brain injury. This is done by maintaining blood
pressure and providing adequate profusion.
After managing ABCDEs of TBI what MUST be identified if present? How is
this done? Correct ans - mass lesion that requires surgical evacuation
is critical! this is done with CT. NOTE: obtaining a CT should not delay patient
transfer to trauma center.
Which brain lobes do the following hold:
1. anterior fossa:
2. middle fossa:
3. posterior fossa: Correct ans - 1. anterior fossa: frontal lobes
2. middle fossa: temporal lobes
3. posterior fossa: lower brainstem and cerebellum
What are the 3 layers of the meninges? Correct ans - dura mater,
arachnoid mater, pia mater
What does the dura mater adhere firmly to? Correct ans - the skull.
it is tough and fibrous

enclose large venous sinuses? What do these sinuses do? Correct
ans - dura mater.
these sinuses provide major venous drainage from the brain.
What is the midline sinus of of the brain that splits into two sinuses: bilateral
transverse and sigmoid sinus? What side are these bigger on? Correct
ans - The main sinus enclosed by the dura major is the midline superior
sagital sinus. This splits into the sigmoid and bilateral transverse sinuses
which are larger on the right side.
What are the arteries that lie between the skull and the dura mater (epidural
space)? Correct ans - meningeal arteries.
What is the most commonly injured meningeal artery and where is it
located? Correct ans - middle meningeal artery.
Located over the temporal fossa
T/F: the arachnoid mater is fused to the dura mater? Correct ans
- FALSE: not
attached. This produces a potential space for a subdural hematoma

In a subdural hematoma, what is the cause? Correct ans - injury to
bridging veins that extend from brain surface to the sinuses within the dura.
fills the space between the arachnoid and pia mater? Correct
ans - CSF. this cushions the brain and spinal cord.
What location of brain hemorrhage is frequently seen in brain contusion or
injury to major blood vessels at base of brain? Correct ans -
subarachnoid.
The and contain the reticular activating system which is
responsible for . Correct ans - midbrain and upper pons
state of alertness
What important function resides in the medulla? Correct ans
-
cardiorespiratory centers.
What important functions are in the following brain segments:
1. left hemisphere:
2. frontal lobe:
