Breathing

Heartbeat

Etc.

4

What is the cerbral cortex?

The outer layer of the brain

The periphery

5

Where does the word "cerebral" come from?

The word for "cork" or "bark"

6

The cerbral cortex is the thin outer layer of the _____ the contains the _____ (______)

Cerebrum

Neural Tissue (Neurons)

7

No

Some are thicker and some are thinner

8

What is the triple layer of bone called?

Diploe

9

What are the three meninges called?

Dura Mater

Arachnoid Mater

Pia Mater

10

What is the Dura Mater?

 

(2)

Outermost meninge

A tough, leathery fibrous lining that attaches to the skull

11

What does Dura Mater mean?

Tough Mother

What are the Arachnoid Trabeculae?

Delicate strands of connective tissue that loosely connect the arachnoid mater and the pia mater

19

What do the Arachnoid Trabeculae do?

Creates the subarachnoid space which contains cerebrospinal fluid

20

What does Pia Mater mean?

Gentle Mother

21

What is the Pia Mater?

Most inferior meninge

Adheres to the brain

22

What does cerebral spinal fluid do?

Helps the brain to float and avoid mild impact injuries

Removes waste created from neural firing

23

What does Epidural mean?

Above the dura mater

24

What is another name for epidural?

Extradural

25

What does subdural mean?

Between the dura mater and arachnoid mater
