Question 3

Which of the following best describes the difference between gray matter and white matter in the brain?

Accepted Answer

Question 5

A patient has a subdural hematoma. Between which two layers of the cranial meninges has the blood accumulated?

Question 19

Which equation best represents the flow of cerebrospinal fluid (CSF) from production to reabsorption?

Accepted Answer

$$Choroid\ plexus \rightarrow Lateral\ ventricles \rightarrow Third\ ventricle \rightarrow Cerebral\ aqueduct \rightarrow Fourth\ ventricle \rightarrow Subarachnoid\ space \rightarrow Arachnoid\ granulations$$
