What is significant about the epidural space? - CORRECT-ANSWER-It
contains the middle meningeal artery (a branch off of the external
carotid)
,What goes through foramen spinosum? - CORRECT-ANSWER-middle
meningeal artery
An ___________ _____________ is typically the result of traumatic
rupture of the MMA due to temporal bone fracture. May initially be
asymptomatic but within hours have increased ICP, herniation, and
death. - CORRECT-ANSWER-Epidural hematoma
The ____________ space is between the dura and the arachnoid.
Contains bridging veins that cross at the subdural space and drain into
the venous sinuses. - CORRECT-ANSWER-Subdural
What is a subdural hematoma? - CORRECT-ANSWER-Rupture of the
bridging veins which are susceptible to shear forces. Two types: chronic
