Quiz 4: Blood Supply, Meninges, Ventricles Flashcards
Which arterial system serves the most caudal part of the brain?
Vertebral arteries –> Posterior cerebral arteries (PCA)
Which artery serves the perisylvian area, which on the left hemisphere contains many language functions?
Internal Carotid –> Middle Cerebral Artery (MCA)
What is the importance of the Circle of Willis?
joins the brain’s two arterial sources of blood
–the vertebral and internal carotids
allows blood to flow in case an artery is blocked
List the 3 Meninges from outermost to innermost
Dura mater
arachnoid
Pia mater
Which of the meninges is hard and tough like leather?
The dura mater, which is the toughest of the meninges. It has 2 layers.
–Outer layer – toughest, supports meningeal arteries that course through dural layer
–Inner layer – more elastic
–2 layers are tightly bound together
What is an ischemic CVA?
Ischemic Cerebral Vascular Accident:
when you have some kind of blockage that keeps blood flow from reaching parts of your brain.
This can be due to a build up of plaque, clot, bubble (Thrombus)
Or a traveling piece of plaque (Embolus)
The ventricles are. filled with ________, one purpose of which is to ________________.
Cerebrospinal Fluid (CSF)
Cushion, nutrient delivery, waste removal
One bilateral structure in the ventricular system of the brain is the __________
lateral ventricles
The third ventricle is connected to the fourth ventricle by the __________
Cerebral aqueduct
Which ventricle is located in the cavity of the diencephalon?
Third Ventricle
Which color is the Lateral Ventricle?
Which color is the Corpus callosum?
LV: Blue
CC: orange.
Which letter is the corpus callosum?
Which letter is the lateral ventricle?
CC: b
LV: c
