11
Q
- What blood vessel enters the cranium to supply the brain with fresh, oxygenated blood?
a. common carotid artery
b. jugular vein
c. internal carotid artery

12
Q
- Which layer of the meninges surrounds and supports the sinuses that form the route through which blood drains from the CNS?

A
A: meningitis (lead to symptoms such as headache, fever, and neck stiffness)
B: Lumbar Puncture (To collect CSF in the clinical condition, but not directly referring to stroke)
C: harms brain health but not related to stroke
D: Because blood to brain is disrupted
