**_🧠Neurology🧠 - Cerebral Vasculature Flashcards
What are the perfusion demands of the brain?
10-20% of cardiac output
20% of total body oxygen consumption
66% of liver glucos
What do the perfusion demands leave the brain very vulnerable to?
Extremely vulnerable to any impairment of blood supply
What major vessels supply blood to the brain?
Vertebral artery
Common carotid artery - splits into internal and external

What layer sits immediately deep to the skull?
Dura mater
What are the two layers of the dura mater?
Periosteal and meningeal
Which layer of the dura mater forms structures?
Only the meningeal dura mater folds inwards to form structures, such as the falx cerebri and tentorium cerebelli
Periosteal dura mater stays tightly adhered to the skull
Where do venous sinuses form?
Form in gaps between the two layers of the dura mater
