1

neurocranium is?

bones that cover brain

2

pterion is?

the H on the temporal region where frontal, parietal, sphenoid, temporal

3

what runs beneath the pterion?

middle meningial artery. if you get hit from the side, this guy gets mad

4

what CNs go through jugular foramen?

CN IX, X, XI

5

hypoglossal canal for what CN?

CN XII

6

foramen rotundum holds what CN?

CN V2

7

sinuses can be for

either blood or air.

8

bregma is?

landmark where coronal and saggital sutures meet between the two parietal bones and frontal bone

9

lambda is?

landmark where the lambdoidal suture meets the saggital suture

10

vertex is?

highest part of the skull. not really sure what he means by that

11

granular foveola

mushroom areas of dura that etch into the bone where the arachnoid granulations sit

12

superior saggital sinus connects to?

lateral venous lacuna

13

what should you pay attention to when you study foramina?

What bone are they in? are they at a bony junction?

14

galea aponeurotica

"goes from the front to the back" of the skull and it is the origin of the occipitofrontalis frontal body, auricularis superior, occipitofrontalis occipital belly. ALL these are innervated by CN VII

15

layers of scalp?

Skin, Connective tissue (dense), Aponeurosis, loose areolar tissue, bone. blood vessels tend to run in subQ

16

, What is Diploe

the spongy bone in the middle layer of the skull. it gets thicker or thinner based on muscle attachments

17

t/f superior saggital sinus is beneath the dura

true

18

primary sensory nerve of scalp?

Trigeminal

19

which word should you be able to spell?

ophthalmic

20

Which trigeminals are purely sensory

1,2

21

where is the trochlea?

trochlear is a pully on the inside of the orbit that a muscle goes around. thats why the V1 nerve has supratrochlear, infratrochlear branches

22

inside your orbit ____comes off V2

zygomatic and splits to z.temportal and z.facial

23

back of head (behind ear) is innervated by?

spinal nerves from cervical plexus. don't forget that C1 doesn't have a dermatome

24

if you get a tattoo behind your ear, which nerve will relay that pain

great auricular C2,3 (anterior rami!!)

25

blood vessels of scalp are primarily from?

ICA and ECA

26

what do superficial temporal, facial, occipital, posterior auricular arteries have in common

come from ECA

27

most veins of the nead and neck drain to ___

IJV

28

outer part of dura, adjacent to the bone is technically not dura. what is it, and what is it called?

its periosteum and its called the periosteal layer of dura. the true dura is the meningeal layer of the dura

29

where does the periosteal layer of dura end?

foramen magnum

30

T/F arachnoid and pia are from two different embryological layers

false. they used to be one layer and then the space got bigger. thats why the arachnoid is kinda stringy
