Flashcards in W19-L10: Meninges Deck (14):
1

Function of the meninges

Prevent rotation of the brain

2

Falx cerebri

lies in midline between two cerebral hemispheres (in sagittal plane), attaches to crita galli ant. and post. to internal aspect
of external occipital protuberance

3

Tentorium Cerebelli

roofs over
post. cranial fossa separates cerebellum and occipital lobe, attaches to marigins of post cranial fossa

4

falx cerebelli

separates hemispheres of cerebellum beneath tentorium cerebelli

5

diaphragma sellae

roofs over pit where pituitary gland
sits

6

Venous sinuses of Dura mater receive blood from where?

sinuses recieve
blood from scalp (emissary vein) and spongey bone (diploic vein)
and brain

7

Venous sinuses of Dura mater

endothelial lined spaces that exist between two layers of dura

8

straight sinus

where ISS meets great cerebral vein of galen (where falx cerebri meets tentorium)

9

cavernous sinus

either side of the body of the sphenoid in which some structures
run

10

transverse sinus

after confluence of sinuses and runs in the root of tentorium cerebelli

11

sigmoid sinus

At the petrous bone (edge of middle cranial fossa) sinus leaves tentorium and runs down into jugular foramen

12

Middle Meningeal Artery is a branch of the which artery?

branch of the maxillary artery

13

Where does the middle meningeal artery enter the skull?

middle meningeal artery enters by foramen spinosum, grooves the internal
surface of the pterion (divides into ant. and post components)

14

Most common causes of subdural haemorrhage

tearing of cerebral bridging veins where they meet the SSS
