Q

Post cerebral artery supplies?

A

post cerebral cortex
medial/lateral occipital lobe
inferior surface of temporal lobe

22
Q

calcarnie branches supply blood to

A

primary visual cortex

23
Q

Middle cerebral artery supplies

A

lateral portion frontal, parietal, temporal lobes
basal ganglia
internal capsule
motor speech area
wernicke’s area

24
Q

Anterior cerebral artery supplies?

A

medial side of frontal and parietal lobes

25
Q

What passes through cavernous sinus?

A

CN III, IV, VI
Opthalmic and maxillary dvisions of CN V
Internal Carotid Artery

26
Q

pterygoid plexus of veins

A

receive venous drainage:
opthalmic veins
cavernous sinus
both via emissary veins
infection route

27
Q

CSF production

A

CSF - nutrition and mechanical support
avg adult volume 150-200ml
prouced in 2 lateral, 3rd, and 4th ventricles by choroid plexus
usually produce 500-1200ml.24hours

28
Q

Choroid plexus

A

tuft of capillaries covered by ependymal cells

29
Q

how does CSF get to subarachnoid space?

A

dorosmedian aperature (foramen of magendie)
lateral foramina

obstruction of these channels can cause hydrocephaly

30
Q

CSF absorption

A

arachnoid villa (granulations) absorbed (mostly) into the superior sagittal sinus

31
Q

large calcified villi are?

A

pacchionian bodies. Can’t absorb CSF as well. Older adults can get senile hydrocephalus

32
Q

Normal CSF presure

A

8-15mmHg lying down
16-24mmHg standing up

33
Q

Lateral olfactory fibers run to?

A

primary olfactory area in temporal lobe

34
Q

medial olfactory fibers run to?

A

paraolfactory area

35
Q

Function of CN III IV & VI

A

extra-ocular movements

36
Q

CN III

A

all eye muscles except sup oblilque m and lateral rectus m.
pupil constriction and other autonomic function of the eye

37
Q

sup oblique m. innervation

A

CN IV trochlear m.

38
Q

lateral rectus innervation

A

CN VI abducens

39
Q

ciliary muscle of the eye function

A

distance accomodation

40
Q

Uncal herniation

A

causes compression of oculomotor nerve

41
Q

trochlear nerve

A

only cranial nerve emerging dorsally
smallest cranial nerve
only cranial nerve that is crossed (sup. medullary vein)
sup oblique muscle (down and out)

42
Q

Close the jaw?

A

masseter & medial pterygoid & temporalis

43
Q

open the jaw

A

gravity
lateral pterygoid and suprahyoids

44
Q

Where to medial and lateral pterygoid muscles reside?

A

Infratemporal fossa

45
Q

Which cranial nerves have parasympathetic activity?

A

III, VII, IX, X

46
Q

Pre-vertebral ganglia

A

celiac ganglia
sup. mesenteric ganglion
inf mesenteric ganglion
aortico-renal ganglia (at aortico-renal junction)

47
Q

What bypass sympathetic chain?

A

prevertebral ganglia

48
Q

White rami communicantes

A

myelinated-preganglionics

49
Q

Gray rami communicantes

A

unmyelinated post gangliionics

50
Q

Where do white and gray rami meet?

A

sympathetic chain
