29
Q

What does the lateral sulcus separate?

A

Temporal lobe from the frontal and parietal lobes

30
Q

Parieto-occipital sulcus

A

Separates parietal and occipital lobes

31
Q

Corpus callosum

A

Connects each side of the brain and allows them to communicate

32
Q

What is the function of the hypothalamus?

A

Homeostasis

33
Q

What cranial nerves is the midbrain associated with?

A

3 and 4

34
Q

What cranial nerve is the pons associated with?

A

5

35
Q

A

9,10 and 12

36
Q

What cranial nerves are associated with the junction between the medulla and pons?

A

6 and 8

37
Q

What are the ventricles of the brain responsible for?

A

Production, transport, and removal of cerebrospinal fluid

38
Q

Where is the main site for cerebrospinal fluid absorption?

A

Arachnoid granulations

39
Q

What does the cerebrospinal fluid provide cushioning for?

A

Blows to the head

40
Q

What is the function of the cerebrospinal fluid?

A

Provides buoyancy that prevents brain from compressing cranial nerves and blood vessels

41
Q

What is the only way for the cerebrospinal fluid to enter the subarachnoid space?

A

Apertures
