Q

What travels through the cavernous sinus?
Clinical significance?

A

ICA, CN III, IV, V (opthalmic and maxillary), VI
Route for infection into brain

17
Q

What are the ventricles?

A

Filled with CSF

18
Q

Ventricle names

A

Lateral ventricles, 3rd ventricle, 4th ventricle

19
Q

3 horns of lateral ventricles

A

anterior horn- into frontal lobe
posterior horn- into temporal lobe
inferior horn- into occipital lobe

20
Q

3rd ventricle- which structures flank it?

A

thalamus and hypothalamus

21
Q

what connects the lateral and 3rd ventricles?

A

Foramen of monroe

22
Q

what connects 3rd and 4th ventricles?

A

cerebral aqueduct (passes through midbrain)

23
Q

what sits anterior and posterior to the 4th ventricle?

A

anterior- pons and medulla
posterior- cerebellum

24
Q

Where does the ACA run and supply?

A

Runs over corpus callosum
Supplies medial structures and strip surrounding longditudinal fissure

25
Q

Where does MCA run?

A

Runs in lateral sulcus (between frontal and temporal)- supplies lateral cortex

26
Q

Where does posterior circulation supply?

A

Hindbrain and inferior/posterior cerebrum

27
Q

what does PCA supply?

A

Occipital, inferior and medial temporal lobes

28
Q

3 cerebella arteries

A

superior cerebellar
anterior inferior
posterior inferior

29
Q

how many communicating arteries in circle of willis?

A

2
anterior (connects 2 ACAs)
posterior (connects basillar and ICA)

30
Q

where do the external cerebral veins drain?

A

Into the DVS

31
Q

Where does the ICA enter the skull?

A

Through the carotid canal in the temporal bone

32
Q

Where is the optic canal? What does it contain?

A

In the sphenoid bone- contains the opthalmic artery and optic nerve

33
Q

most anterior bone on skull base?

A

ethmoid bone

34
Q

What runs through the superior orbital fissure?

A

Superior opthalmic vein

35
Q

What does the middle meningeal artery supply?
Where does it travel?

A

Skill, skull, dura
Travels through foramen spinosum

36
Q

What does the internal acoustic meatus contain?

A

Labrinthyine artery, CN VII, VIII
Can get pulsatile tinitus- hear own heart beat when pulsating artery is pressing against cochlear component of VIII
