Question 1

What are the meninges of spinal cord called

Answer 1

1. Dura mater spinalis
2. Arachnoidea spinalis
3. Pia mater spinalis

Question 2

What are the meninges and folds of cerebrum called

Answer 2

1. Dura mater encephali
   >Falx cerebri
   >Tentonium cerebelli membranacea
   >Falx cerebelli
   >Diaphragma sellae
2. Arachnoidea encephali
3. Pia mater encephali

Question 3

Pia mater; spinalis et encephali

Answer 3

> Thin, innermost
Fibrous tissue
High blood supply
On surface of the spinal cord and brain
Forms lig. denticulatum that stabilizes the
spinal cord
Interpermeable to fluid
Forms cisterna cerebellomedullaris with arachnoid when the interval between them is larger

Question 4

Arachnoidea: spinalis et encephali

Answer 4

> No blood vessels
Granules move cerebrospinal fluid to bloodstream
Attached to dura and pia mater
In contact with sinus durae matris by granulationes arachnoidales

Question 5

Dura mater: spinalis et encephali

Answer 5

> Outermost
Pain sensitive
Thickest
Also called pachymenix
Blood vessels
Forms the folds in brain:
-Falx cerebri
-Tentorium cerebelli membranacaeum
- Diaphragma sellae
-Falx cerebelli

Question 6

Cavum epidurale

Answer 6

> Located dura mater and bones of vertebrae
Filled with adipose
Blood vessels
Regional anesthesia between last sacral and first caudal vertebrae, or first and second caudal vertebrae (epidural)

Question 7

Cavum subdurale

Answer 7

> Artificial cavity
Between dura mater and arachnoidea
Serous fluid
Created by trauma or ongoing pathological process

Question 8

Cavum subarachnoidale

Answer 8

> True cavity
Between Pia mater and Arachnoid
Cerebrospinal fluid
Blood vessels that enter the brain
Lumbar cistern
Cisterna cerebellomedullaris

Question 9

Cavities of cerebrum

Answer 9

1. Cavum subdurale
2. Cavum subarachnoidale

Question 12

What is the function of tentorium cerebelli membranaceum

Answer 12

Divides the cerebellum and pons from lobus occipitalis

Question 13

What is the function of Falx cerebelli?

Answer 13

Divides hemispheres between cerebellum,
Absent in domestic animals

What is the function of diaphragma sellae

Answer 14

Smallest dural infolding
Located in hypophysial fossa, covers glandula pituitaria (hypophysis)

Question 15

What is the role of Granulations of Arachnoidea ? (granulationes arachnoidales)

Answer 15

Transfer CSF (cerebrospinal fluid) / liquor cerebrospinalis back to the blood

Question 16

Between which structures is the Cisterna cerebellomedullaris?

Answer 16

Between atlas and skull (articulatio atlanto-occipitalis)

Question 17

What is the other name of dura mater?

Answer 17

Pachymeninx

Question 18

What is another name for arachnoidea and pia mater?

Answer 18

Leptomeninx

Question 19

How does pia mater stay in place?

Answer 19

Forms triangular ligaments: ligamenta denticulata, which attach it to dura mater, arachnoidea and spinal cord
