Question 1

All 8 branches of the external carotid A in order as it ascends

Accepted Answer

1.Superior Thyroid.
2.Ascending Pharyngeal.
3.Lingual.
4.Facial.
5.Occipital.
6.Posterior Auricular.
7.Maxillary.
8.Superficial Temporal

Question 2

What nerve does the Superior thyroid A travel with?

Accepted Answer

Internal branch of Superior Laryngeal N

Question 3

What Artery comes off the Superior Thyroid A?

Accepted Answer

Superior Laryngeal A

Question 4

Does the inferior thyroid Vein travel with the inferior thyroid A?

Accepted Answer

No, the inf thyroid A comes off the thyrocervical trunk lateral to the trachea while the veins travel down the midline of the trachea to the bracheocephalics.

Question 5

What is the only medial branch of the Ext Carotid A?

Accepted Answer

Ascending Pharyngeal A. (2nd branch off the ECA)

Question 6

Where will you find the Lingual A?

Accepted Answer

(3rd branch off the ECA)Runs with the Hypoglossal nerve (CN XII) deep to stylohyoid and Post. Digastric.

Question 7

Arteries derived from the facial artery

Accepted Answer

(4th branch off ECA) 
1.Inferior Labial A.
2.Superior Labial A.
3.Angular A (stays in the nasal-labial crease)

Question 8

CN XII exits the skull directly below what artery?

Accepted Answer

Occipital A

Question 9

Temporal Arteritis

Accepted Answer

Patient presents with scalp/eye pain, extreme head aches, and dilated vasculature in temporal region.

Question 10

Branches off the Maxillary A

Accepted Answer

1.Middle Meningeal.
2.Inferior alveolar.
3.Spehnopalatine.
4.Superior Alveolar.
5.Infraorbital.
6.Greater Palatine

Question 11

What arteries are responsible for nose bleeds?

Accepted Answer

Kiesselbach's plexus:
1.Sphenopalatine A.
2.Superior labial A.
3.Greater Palaine A.
4.Anterior Ethmoid A.

Question 12

Where does the Middle Meningeal A enter the skull?

Accepted Answer

Foramen Spinosum. It then is found in the grooves on the temporal bones.

Question 13

Epidural Hematoma

Accepted Answer

Spread of BL from lateral skull blunt trauma is in the epidural space. Movement laterally is limited by dural attachment to inner skull table which causes a midline shift. Therefore they feel initial pain and then a "lucid interval"

Question 14

Presentation of "normal/textbook" Circle of Willis

Accepted Answer

Only seen in about 20-25% of pop

Question 15

What Artery runs inferior to CN VI-X?

Accepted Answer

Anterior Inferior Cerebellar A

Question 16

What Artery runs between CN I and CN II?

Accepted Answer

Anterior Cerebral A

Question 17

What Artery runs over the Hypoglossal N?

Accepted Answer

Posterior inferior cerebellar A

Question 18

What CN does the posterior cerebral cross superiorly?

Accepted Answer

CN III oculomotor. **superior cerebellar is just behind and inferior to CN III

Question 19

Most common site for a Subarachnoid Hemorrhage?

Accepted Answer

Anterior communicating A. (Congenital saccular aneurysm)

Question 20

How would Patient present with a subarachnoid hemorrhage of Ant comm A? Post comm A?

Accepted Answer

Ant: Worse head ache of their life, vision loss.
Post: Worse head ache of their life with occulomotor loss

Question 21

Subdural hematoma

Accepted Answer

Rupture of Bridging Veins. Delayed onset of symptoms and NO midline shift b/c blood can spread laterally across suture lines.

**Seen with SHEARING force (whiplash, shaken baby syndrome)

Question 22

Danger Triangle

Accepted Answer

The facial v can drain to the cavernous sinus via superior/inferior opthalmic v. Therefore you can infection can spread there causing meningitis.

Question 23

Emissary Veins

Accepted Answer

Allow infection to spread from the scalp to the cranial cavity. They pass through parietal foramina

Question 24

Structure located on lateral wall within the cavernous sinus?

Accepted Answer

CN III, IV, V1, V2.

Question 25

Structures located centrally on either side of the cavernous sinus?

Accepted Answer

CN VI and Internal carotid A

Question 26

Cavernous Sinus Thrombosis (CST)

Accepted Answer

complication of untreated sinusitis or facial infection. 
**patien presents with eye swelling, HA, loss of corneal reflex.

Question 27

Corneal Reflex

Accepted Answer

Poke eye, both eyes blink. Senory arm: V1. Motor arm: VII
