1

Name the structures from subclavian arteries to top

Anterior spinal artery
Vertebral arteries
Posterior Inferior arteries
Anterior inferior arteries
Labyrinthe arteries
Basilar arterie
Superior cerebral arteries
Posterior cerebral arteries
Posterior communicating arteries
Middle cerebral arteries
Internal carotid artery
Ophthalmic artery
Anterior communicating artery
Anterior cerebral artery

2

From which arteries do the left and right vertebral arteries arise

Subclavian arteries

3

At what vertebral level do the left and right internal carotid arteries arise

C4

4

How is the basilar artery formed and which part of the brainstem is it most closely related to

2 vertebral arches join together and Medula

5

What arteries complete the posterior of the circle of of Wilis by linking the internal carotid arteries to the posterior cerebral arteries

Posterior communicating arteries

6

Which artery completes the anterior of the circle of Willis by linking the anterior cerebral arteries

Anterior communicating artery

7

Which fissure does the anterior cerebral artery

Medial aspect- longitudinal fissure

8

What sulcus does the middle cerebral artery travel

Cerebral sulcus

9

What sulcus does the posterior cerebral artery trace through

Calcarine sulcus

10

Which artery supplies the primary motor cortex

Middle

11

Which artery supplies the primary sensory area

Anterior

12

Which artery supplies the primary visual cortex

Posterior

13

Which artery supplies the primary auditory area

Middle

14

What artery supplies the area of olfaction

Middle

15

What parts of the brain do the vertebrobasilar system supply

Brainstem, occipital lobes and cerebellum

16

Which cerebral artery runs immediately superior to the superior cerebellar arteries

Posterior cerebellar arteries

17

Which cranial nerve emerges from just above the superior cerebellar artery

Trochlear and Oculomotor

18

Aneurysms of the posterior cerebral artery are common at the location, often resulting in palsy of the cranial nerve III (oculomotor)

Palsy of oculomotor- eye is displaced downward and outwards

19

Describe the carotid sinus location and its function

Located at terminal part of the common carotid artery.
It is a pressure receptor which monitors the flow to the head. Sensory nerves from the carotid sinus run in the glossopharyngeal nerve and the vagus nerve

20

Describe the carotid body and function

Area on the posterior wall of the terminal part of the common carotid artery in the neck. Contains chemoreceptors which are sensitive to low oxygen levels (anoxia) (HR, respectively rate, and BP). Sensory nerves from these receptors run in the glossopharyngeal nerve

21

Where does the sympathetic motor nerves run from

Plexus enters the skull with the artery through the carotid canal and continues along the main branches of the internal carotid artery

22

The brain is drained by a series of veins which drain into where?

Dural venous sinuses between the periosteum and the cranial dura

23

Name the larger intracranial venous sinuses

Superior sagittal sinus
Inferior sagittal sinus
Straight sinus
Transverse sinus
Sigmoid sinus
Confluence
cavernous sinus
Petrosal sinus
Great cerebral vein
Superior ophthalmic vein

24

Into which vein in the neck do the dural venous sinuses drain into

Jugular vein

25

Through which foramen in the skull does the jugular vein pass through

Jugular foramen

26

Where does the superior ophthalmic vein drain into

The cavernous sinus within the cranial cavity

27

What is the superior ophthalmic vein continuous with outside the cranial cavity

Facial vein

28

What are emissary veins

They connect the cranial venous sinuses with the dipole of the skull containing blood sinuses in the bone marrow, which in turn are continuous with the veins in the superficial fascia overlying the outer part of the skull and scalp

29

Where are the inferior petrosal sinuses lie

At the base of the brain and are connected to each other by the basilar sinus

30

What are the grooves in the base of the skull

Cavernous sinus
Groove for sigmoid sinus
Groove for transverse sinus
Groove for confluence of sinus
Sagittal sinus
