mater
Arachnoid mater
Dura mater
What layer of meninges is perforated to allow cranial nerves and blood vessels to pass through?
- ANS Dura mater
What function does the dura mater has, because it is a perforated layer? - ANS Allows cranial
nerves and blood vessels to pass though
What are the 2 layers of the outmost layer, the dura mater? - ANS Periosteal layer
Meningeal layer
Where does the spinal dura meet with the meningeal layer? - ANS Foramen magnum
Separations of the dura membranes create what? - ANS Sinuses
Sinuses are separations of the dura membranes. Why are they important? - ANS Venous
drainage system functions

,What is a fold in the dura? - ANS Septums
Septums are dura folds in a few places that have what function? - ANS Separates brain
structures
What is the function of the fold of dura in the longitudinal fissure? What is this structure called?
- ANS Falx Cerebri

What are the 2 main folds of dura in the brain? - ANS Falx Cerebri
Tentorium cerebelli
What is the falx cerebri? - ANS Dura fold that separates the right and left hemisphere in
longitudinal fissure
What is the tentorium cerebelli? - ANS Dura fold occurs at back of brain and divides cerebral
hemispheres from cerebellum
What is the dura fold that primarily divides the occipital lobes from the cerebellum? -
ANS Tentorium cerebelli

head is moved or stopped quickly, the brain tissue can move and abrade at the dural edges
causing lacerations

during a high speed impact to the head? - ANS Falx Cerebri: Corpus callosum could be
damaged
Tentorium Cerebelli:
Midbrain
Oculomotor nerve
What meninges layer adheres to the dura mater - ANS Arachnoid mater
What is the thin mininge layer that is thinner and more delicate than the dura but not as
delicate as the pia mater - ANS Arachnoid mater
The arachnoid mater gets it's name because it has a _______________ appearance -
ANS Spiderweb like
Describe the location of the arachnoid membrane - ANS In middle layer of meninges layer
between dura and pia.
What is the function of the subarachnoid space? - ANS Suspend the brain
What space is between the pia and arachnoid layers and has trabeculae that suspend the brain?
- ANS Subarachnoid space
What serves as 1 way valves to the dural sinus? - ANS Arachnoid granulations
What meningie layer follows the contours of the brain? - ANS Pia mater
