◉Which layer of the meninges is perforated to allow room for cranial
nerves and blood vessels? Answer: Dura mater
◉Separations of the ________ membranes create sinuses that are
important for the venous drainage system. Answer: Dura
◉The _____________ layer has trabeculae that suspend the brain.
Answer: Arachnoid
◉True or false:
Arachnoid granulation serve as one way valves to the duralumin sinus.
Answer: True
◉True or false:
Dentate ligaments are pia mater. Answer: True
,◉What is significant about the epidural space? Answer: It contains the
middle meningeal artery (a branch off of the external carotid)
◉What goes through foramen spinosum? 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. 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. Answer: Subdural
◉What is a subdural hematoma? Answer: Rupture of the bridging veins
which are susceptible to shear forces. Two types: chronic (elderly) and
acute
◉The _______________ space is between the arachnoid and pia mater.
Contains major arteries of the brain as well as CSF. Answer:
Subarachnoid
◉What is a subarachnoid hemorrhage? Answer: Two types: traumatic

Diencephalon (thalamus)
◉What is the flow of CSF? Answer: Lateral ventricles through the
foramen of Monroe to the 3rd ventricle through the cerebral aqueduct to
the 4th ventricle and out through the foramen of magendie
◉True or false:
The choroid plexus exists within each of the ventricles and is constantly
producing CSF, creating a small pressure gradient. Answer: True
(functions are buoyancy, cushioning, cleaning, and ionic balance)
◉The choroid plexus is made of _____________ cells that produce CSF
and assist in circulating it by movement of their cilli. Answer:
Ependymal
◉_________ are large pockets in the subarachnoid space. Answer:
Cistern
