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

periosteal
|
|
... is the dura layer that is closest to the brain
|

|
name the labeled structures:
a. b. |
a. falx cerebri

|
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
|
|
identify the labeled structures:
a. b. c. d. e. |
a. periosteal layer
b. meningeal layer c. dura mater d. epidural space e. subdural space |
|
a. extradural (epidural)
b. subdural |
identify where the hemorrhage is:
a. b. |
|
a. epidural space
b. epidural space |
identify the area labeled:
a. b. |
|
epidural
subdural intracerebral |
identify the labeled hematomas:
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. |
name the circled area and what is it's significance?
|
|
is the subarachnoid space real or potential?

real
|
|
what do you find in the subarachnoid space?
