Question 11

Match the following structures to their descriptions by using the following answer code.
-initial cortical processing for hearing

Accepted Answer

The initial cortical processing for hearing occurs in the temporal lobe of the brain.

Question 12

-venous blood draining from the brain empties here

Accepted Answer

Dural sinuses are responsible for draining the venous blood from the brain.

Answer: A 
 Arachnoid villi project into the dural sinuses to help with drainage of cerebrospinal fluid.

Answer: C 
 Choroid plexuses are responsible for producing cerebrospinal fluid rather than draining venous blood.

Answer: B 
 The subarachnoid space is a cavity between the arachnoid and pia mater where cerebrospinal fluid circulates, but it is not directly involved in draining venous blood.
