what are meninges
connective tissue
meninges surround the ... and ...
brain
spinal cord
the brain and spinal cord together form the ...
central nervous system (cns)
the three layers of the meninges are:
1.
2.
3.
1. dura
2. arachnoid
3. pia
the thickest of the meninges is the ... and it is the outermost layer
dura
this meninges layer is attached intimately with the brain and cannot be pealed away.
pia
this meninges layer is thin and spider-like and lies just beneath the dura.
arachnoid
this benign tumor of the brain is typically encapsulated and grows on the underside of the dura and does not invade the brain
meningioma
there are/is ... layer(s) of dura around the spinal cord and ... layer(s) of dura around the brain
one
two

there are ... in-foldings of meningeal layer in the skull
3
the meningeal folding ... lies mid-sagittal between cerebral hemispheres
falx cerebri
the meningeal folding ... lies mid-sagittal between cerebellar hemispheres
falx cerebelli (small)
the meningeal folding ... lies horizontal between occipital lobes and cerebellum
tentorium cerebelli
name the labeled structures:
a.
b.
a. falx cerebri
b. tentorium cerebelli
is the epidural space in the brain real or potential?
potential - blood can get in here and create a real space
is the epidural space in the spinal cord real or potential?
real - contains fat & veins; here is where you do epidural
anesthesia
is the subdural space real or potential?
potential
where is the subdural space located?
below the dura and on top of the arachnoid

b.
c.
d.
e.
a. periosteal layer
b. meningeal layer

a.
b.
c.
pterion

-weakest part of the skull
-middle meningeal artery runs beneath it
-bone very thin/fragile
-a blow to the pterion may rupture the artery causing an extradural haematoma.
