5

What do the walls of the cranial cavity consist of ?

Consist of inner and outer tables of compact bone that are separated by spongy bone called diploë

6

What are the cranial meninges?

Three membranes that surround the brain and are continuous with the meninges of the spinal cord.

7

_____ mater is fused to the periosteum, therefore it is considered to have two
parts

*Dura mater* meninge is fused to the periosteum, therefore it is considered to have two
parts

8

What are the two parts of the dura mater?

11

____ mater is a delicate membrane that lines the inner surface of the dura.

*Arachnoid* mater is a delicate membrane that lines the inner surface of the meningeal dura.

12

What is the arachnoid trabeculae?

Fine extensions that span across the subdural space and attach to the pia mater.

13

What is the pia mater?

Vascular delicate membrane that attaches to the brain.

14

True or False

The subdural space of the brain and spinal cord are the same

True

15

The separation of ___ from ___ creates channels that are lined with an ___ and receive veins that drains the ___ and the ___

The separation of *meningeal dura from periosteal dura* creates channels that are lined with an *endothelium* and receive veins that drain the *brain and the meninges.*

16

The channels created by the separation of the meningeal dura from periosteal dura are in effect venous channels responsible for draining the
____

The channels created by the separation of the meningeal dura from periosteal dura are in effect venous channels responsible for draining the
*contents of the cranial cavity.*

17

At other locations, the meningeal dura form folds that dip into ___ between parts of the brain.

At other locations, the meningeal dura form folds that dip into *fissures* between parts of the brain.

20

What is the tentorium cerebelli?

A horizontal fold between the cerebrum and the cerebellum underneath it

21

____ dural fold is under the falx cerebri and the tentorium cerebelli, is a vertical dural fold that separates the right and left cerebellum/cereberal lobes
