Meninges are what?
layers of connect tissue that support and float the brain
T/F meninges and ventricles supports the brain and spinal cord
T
how many layers does meninges have?
3 dura mater, arachnoid mater, pia mater
what are the two layers of dura mater
periosteal and meningeal
T/F periosteal is against bone, meningeal faces other meninges in brain lies against arachnoid membrane
T
T/F dura mater is the inner most layer
f outermost
past age ___ brain starts to stick to skull dura becomes attached to skull
60
T/F periosteal and meningeal can not separate
F
Two meningeal layers can form ____ forming triangular space between duras called dura sinus
falx (double meningeal layer)
What does the subarachnoid space do
carries ceribrialspino fluid , wraps all the way around the brain
T/F there is subdural space (potential space) between meningeal arteries and end nerves that supply dura
T
T/F a symptom of dilated pupil can tell you that you have a epidural hematoma( bleeding between teh space between dura and skull)
T
Arachnoid membrane is thinner, transparent, similar to _____
saran wrap
the arachnoid membrane lies against what layer?
dura
arachnoind membrane is attached to pia by _______ trabeculae
collagen
what happens if your arachnoid membrane bleeds into subdural space ? is it serious young or old? is it a slow process?
lower pressure , slower takes longer , not as serious young and old
what is the space between arachnoid and pia
subarachnoid space
Which space has the cerebrolspinal fluid
subarachnoid space
What space has the major blood vessels ?
subarachnoid space
T/F subarachnoid space is placed by collagen fibers that look like spiders keep it at a specific distance
T
a ruptured aneurysm bleeds into what space, and what are symptoms? can it come from overexertion or motorcycle accident?
subarachnoid space, worse headache of life, thunderclap
Yes
T/F subarachnoid space inflates and floats brain
T
What is pia mater attached to ?
surface of brain
can pia mater be removed?
no it is the surface of the brain
what mater helps brain hold its shape
pia mater
which mater helps billions of neuraon make up cortex of brain and unable to adhere well
pia mater
