What creates cerebrospinal fluid in the ventricles?

Choroid plexus

6

What are the 3 functions of cerebrospinal fluid?

1. Buoyancy
2. Protection
3. Chemical stability

7

Name the 6 steps in the flow of cerebrospinal fluid

1. Choroid plexus of both lateral ventricles produce CSF
2. CSF flows through the interventricular foramina
3. Into the third ventricle
4. Through the mesencephalic aqueduct
5. Into the fourth ventrilce
6. And into the subarachnoid space between the arachnoid and pia mater

8

Describe hydrocephaly

Swelling of the head caused by overproduction or blockage of CSF

9

Describe meningitis

Swelling of the brain caused by bacterial infections of the meninges

10

What is the purpose of the extensive folds of the brain?

To increase surface area of the brain

What does Wernicke's Area control?

Understanding of written and spoken word

18

What is the function of the occipital lobe?

Allows for visual accuity

19

What is the function of the temporal lobe?
