After managing ABCDEs of TBI what MUST be identified if present? How is this done? correct 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: correct 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? correct answer dura mater, arachnoid mater, pia mater
What does the dura mater adhere firmly to? correct answer the skull. it is tough and fibrous
What layer of the meninges splits into two leaves as specific sites to enclose large venous sinuses? What do these sinuses do? correct answer dura mater.
these sinuses provide major venous drainage from the brain.

What are the arteries that lie between the skull and the dura mater (epidural space)? correct answer meningeal arteries.
What is the most commonly injured meningeal artery and where is it located? correct answer middle meningeal artery.
Located over the temporal fossa
T/F: the arachnoid mater is fused to the dura mater? correct answer FALSE: not attached. This produces a potential space for a subdural hematoma
