SA-Blood flow Flashcards
vertebral artery enters the spine at
C6 transverse foramen
enters skull at foramen magnum
vertebral artery
has no collateral circulation and off of vertebral artery
Posterior inferior cerebellar artery (PICA)
Damage to PICA
Wallenburg syndrome
Wallenburg syndrome is characterized by
ipsilateral loss of pain and temperature to face and contralateral loss to body
provides blood to anterior 2/3 of spine
anterior Spinal artery
provides blood to posterior 1/3 of spine
posterior Spinal artery
Right carotid feeds off of the
brachiocephalic artery
Left carotid comes off of the aorta
aorta
both carotid arteries bifurcate at_____ and become the ____ and _____
C3/C4
internal and external
how does the dura get blood?
external carotid => Maxillary => Middle meningeal artery => dura
middle meningeal artery passes through the _____ to feed the _____
foramen spinosum
dura
the opthalmic artery is the first branch of the
internal carotid (feeds the eye)
The veins of the scalp are drained by the ______ to the superior sagittal sinus
emissary veins
“GREAT IS STRAIGHT”
great cerebral vein drains into straight sinus
Straight sinus is found in the
superior sagittal sinus is found in the
tentorium cerebelli
Falx Cerebri
“Superior is Superior”
Superior Cerebral vein goes into the super sagittal sinus
contains arachnoid granulations to reabsorb CSF
Superior sagittal sinus
blockage of CSF in the ______ leads to _____
Superior sagittal sinus
Hydrocephalus
What is the anterior attachment of the falx cerebri?
posterior attachment of fall cerebra?
crista galli of ethmoid
tentorium cerebelli
confluence of sinuses =
found where?
torculus herophilus
inner portion of the occipital bone
damage to sinuses results in
subdural hematoma
damage to middle meningeal artery
epidural hematoma
damage to venous system
subdural hematoma
subarachnoid hemorrhage results in
Beri aneurysm
flow of CSF
lateral ventricles (vial chloroid plexus by epidymal cells) foramen of monroe 3rd ventricle cerebral aqueduct of sylvius 4th ventricle foramen of magnesia central canal and subarachnoid space reabsorbed in arachnoid villi in superior sagittal sinus
