Q

What is the sensory nerve supply to the skin overlying the angle of the jaw?

Maxillary branch of the trigeminal nerve

Mandibular branch of the trigeminal nerve

C3-C4

Greater auricular nerve (C2-C3)

Buccal branch of the facial nerve

A

The trigeminal nerve is the major sensory nerve to the face except over the angle of the jaw. The angle of the jaw is innervated by the greater auricular nerve.

Q

Which of the following cranial foramina pairings are incorrect?

Carotid canal and internal carotid artery.

Foramen ovale and mandibular nerve.

Optic canal and ophthalmic artery.

Optic canal and ophthalmic nerve.

Foramen rotundum and maxillary nerve.

A

The optic canal transmits the optic nerve. The ophthalmic nerve traverses the superior orbital fissure.

Q

Which of the following is not closely related to the capitate bone?

Lunate bone

Scaphoid bone

Ulnar nerve

Hamate bone

Trapezoid bone

A

The ulnar nerve and artery lie adjacent to the pisiform bone. The capitate bone articulates with the lunate, scaphoid, hamate and trapezoid bones, which are therefore closely related to it.

16
Q

A 22 year old man is undergoing an endotracheal intubation. Which of the following vertebral levels is consistent with the origin of the trachea?

C2

T1

C6

C4

C3

A

The trachea commences at C6. It terminates at the level of T5 (or T6 in tall subjects in deep inspiration).

17
Q

A 30 year old man presents with back pain and the surgeon tests the ankle reflex. Which of the following nerve roots are tested in this manoeuvre?

S3 and S4

L4 and L5
1
L3 and L4

S1 and S2

S4 only

A

S1-S2

18
Q

Lymph drainage of the tongue?

A

Anterior 2/3 -> ipsilateral
Posterior 1/3 -> bilateral
Tip -> submental -> deep cervical
Mid portion -> submandibular -> deep (lateral - ipsi, central - bilateral)

19
Q

Nerve at risk during carotid endarterectomy?

A

Hypoglossal

but also greater auricular, superior laryngeal

20
Q

Motor deficit after submandibular gland excision?

A

Hypoglossal nerve. Lingualis - sensory. Also commonly damaged nerve is the facial.

21
Q

At which level does the inferior thyroid artery enter the thyroid gland?

A

C6!!! Not C4!

C6 - origin of the trachea, lower pole of thyroid lobules

22
Q

Parasympathetic fibres innervating the parotid gland?

A

OTIC ganglion. Not pterygopalatine! (this is for lacrimal)

Glossopharyngeus (IX) -> tympanic nerve -> otic ganglion + postganglionic fibres from auriculotemporal nerve (V3)
IX + V3 + otic ganglion = saliva from parotid

23
Q

Tongue innervation?

A
24
Q

Vein drainage from the tonsil?

A

External palatine vein -> facial vein

25
Q

Arterial blood supply to the lacrimal gland?

A

Ophthalmic artery

Venous drainage to ophthalmic veins -> cavernous sinus

26
Q

Which vessel lies laterally to the inferior parathyroid gland?

A

Common carotid.

Bifurcation of carotids - C4. But inferior parathyroid is on the level of C6!

27
Q

Which part of the face is not innervated by the V nerve?

A

Angle of the jaw - by facial

28
Q

Branches of external carotid artery?

A

Some Angry Old Lady Figured Out PMS

Sup. thyroid
Ascend pharyngeal
Lingual
Facial
Occipital
Posterior auricular
Maxillary
Superficial temporal
29
Q

Branches of internal carotid artery?

A 
Only
Press
Carotid
Arteries
Momentally
Ophthalmic
Posterior communicationg
Choroidal
Anterior cerebral
Middle cerebral

Ant.cer+Mid.cer.
OPC
Ophthalmic Post.comm. Choroidal

30
Q

Where does Stenson’s duct open?

A

Opposite the second molar tooth

31
Q

How does chorda tympnai run according to the membrana tympani?

A

Medial to the pars flaccida (not tensa!)

32
Q

Level of the hyoid bone?

A

C3

33
Q

Vessel in danger during excision of submandibular gland?

A

Facial artery.

Not lingual - it is at risk during dissection of Wharton’s duct

34
Q

From which vessel is middle cerebral artery?

A

From ICA

36
Q

Where does inferior petrosus sinus pass?

A

Jugular foramen
