CLINICAL NEUROSCIENCE TEST REVIEW
QUESTIONS 2026 FULLY SOLVED GRADED A+
⫸ What is the purpose of the scalp? Answer: Protect brain from
outside forces
⫸ Even though the skull provides a strong barrier to protect the
brain. What acts as a secondary line of defense over the brain?
Answer: Meningies
⫸ The meninges cover both brain and spinal cord forming a tight
seal with three membrane structure. What are those 3 membranes?
Answer: Dura mater
Arachnoid mater
Pia mater
⫸ What is the most outermost layer of the meninges? It is also the
thickest and toughest membrane. Answer: Dura mater
⫸ List the layers of the meninges from the innermost layer to the
outermost layer Answer: Pia mater
,Arachnoid mater
Dura mater
⫸ What layer of meninges is perforated to allow cranial nerves and
blood vessels to pass through? Answer: Dura mater
⫸ What function does the dura mater has, because it is a perforated
layer? Answer: Allows cranial nerves and blood vessels to pass
though
⫸ What are the 2 layers of the outmost layer, the dura mater?
Answer: Periosteal layer
Meningeal layer
⫸ Where does the spinal dura meet with the meningeal layer?
Answer: Foramen magnum
⫸ Separations of the dura membranes create what? Answer: Sinuses
⫸ Sinuses are separations of the dura membranes. Why are they
important? Answer: Venous drainage system functions
⫸ What is a fold in the dura? Answer: Septums
,⫸ Septums are dura folds in a few places that have what function?
Answer: Separates brain structures
⫸ What is the function of the fold of dura in the longitudinal fissure?
What is this structure called? Answer: Falx Cerebri
Seperates the right and left hemispheres
⫸ What are the 2 main folds of dura in the brain? Answer: Falx
Cerebri
Tentorium cerebelli
⫸ What is the falx cerebri? Answer: Dura fold that separates the
right and left hemisphere in longitudinal fissure
⫸ What is the tentorium cerebelli? Answer: 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? Answer: Tentorium cerebelli
⫸ What part of the dura mater is important for venous drainage
systems? Answer: Sinuses
, ⫸ The periosteal layer and meningeal layer are part of what
meninges structure? Answer: Dura mater
⫸ How can the falx cerebri and tentorium cerebelli cause damage to
brain tissue? Answer: When head is moved or stopped quickly, the
brain tissue can move and abrade at the dural edges causing
lacerations
⫸ What brain structures would the falx cerebri and the tentorium
cerebelli most likely damage during a high speed impact to the head?
Answer: Falx Cerebri: Corpus callosum could be damaged
Tentorium Cerebelli:
Midbrain
Oculomotor nerve
⫸ What meninges layer adheres to the dura mater Answer:
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 Answer: Arachnoid
mater
