What is the primary goal of treating TBI? How is this done?
ANSWER
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?
ANSWER
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:
ANSWER
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?
ANSWER
dura mater, arachnoid mater, pia mater
What does the dura mater adhere firmly to?
1
,ANSWER
the skull. it is tough and fibrous
What layer of the meninges splits into two leaves as specific sites to enclose large venous si-
nuses? What do these sinuses do?
ANSWER
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?
ANSWER
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)?
ANSWER
meningeal arteries.
What is the most commonly injured meningeal artery and where is it located?
ANSWER
middle meningeal artery.
Located over the temporal fossa
T/F: the arachnoid mater is fused to the dura mater?
ANSWER
FALSE: not attached. This produces a potential space for a subdural hematoma
2
, In a subdural hematoma, what is the cause?
ANSWER
injury to bridging veins that extend from brain surface to the sinuses within the dura.
_______ fills the space between the arachnoid and pia mater?
ANSWER
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?
ANSWER
subarachnoid.
The ____ and _____ contain the reticular activating system which is responsible for ____.
ANSWER
midbrain and upper pons
state of alertness
What important function resides in the medulla?
ANSWER
cardiorespiratory centers.
What important functions are in the following brain segments:
1. left hemisphere:
2. frontal lobe:
3. parietal lobe:
4. temporal:
