1

Location of Asterion

asterion is located laterally on the skull at the junction of the lambdoid, occipitomastoid and parietom astoid sutures.

2

This craniometric point long the sagittal suture represents the most superior aspect of the skull

Vertex

3

located posteriorly on the skull at the junction of the sagittal and lambdoid sutures

Lamba

4

located superiorly on the skull at the junction of the coronal and sagittal sutures

Bregma

5

In an industrial accident, a 58 y.o. man suffers a fracture of the inferior portion of the lateral margin of the orbit. Which bone contributes to this margin of the orbit

Zygomatic

6

bone forms the inferolateral and lateral margins of the orbit

Zygomatic

7

contributes to the medial aspect of the orbit.

lacrimal

8

bone does not contribute to the orbital margin. It forms the bridge of the nose

nasal

9

contributes to the medial aspect of the inferior orbital margin

maxilla

10

passes through the substance of the parotid gland.

Facial N

11

It innervates the muscles of facial expression.

facial nerve

12

Damage to the nerve will result in facial droop.

facial nerve

13

Innervation to the parotid gland is via the

glossopharyngeal n. (CN IX)

14

Innervation of the submandibular and sublingual salivary glands is provided by

the chorda tympani nerve. .

15

Chorda Tympani is a branch of

This branch of CN VII

16

Path of Chorda Tympani

exits the skull via the petrotympanic fissure and does not pass through the substance of the parotid gland

17

Sensory innervation of the check is provided by the

buccal branch

18

Buccal Nerve is from:

of the mandibular division of the trigeminal nerve (CN V).

19

The hypoglossal nerve (CN XII) damage

tonuge paralysis

20

The spinal accessory nerve innervates

the sternocleidomastoid muscle and the trapezius muscle.

21

ansa cervicalis overlies the

carotid sheath which is deep to the sternocleidomastoid.

22

Its branches innervate the infrahyoid muscles.

Ansa Cervicalis

23

These nerves are sensory branches from C3 and C4.

supra clavicular

24

This nerve runs in a groove between the trachea and esophagus.

Recurrent laryngeal

25

It provides motor innervation to intrinsic laryngeal muscles.

Recurrent laryngeal

26

is a sensory branch from C2.

The lesser occipital nerve

27

The artery crosses the mandible just anterior to the masseter muscle.

Facial

28

is a branch of the superficial temporal artery

Transverse facial

29

provides sensory innervation to the tip of the nose, the bridge of the nose, upper eyelid, the forehead and anterior scalp.

V1: opthlamic

30

provides sensory innervation to the upper lip, prominence of the cheek, lower eyelid and along the lateral aspect of the orbit.

V2: maxillary

31

orbicularis oculi muscle, a muscle of facial expression, is innervated by

the facial nerve

32

These three nerves are purely motor nerves that innervate the extraocular muscles.

III, IV, VI

33

nerve is a purely sensory nerve associated with the special sense of vision.

II

34

provides sensation from the lower jaw and side of the face and provides motor innervation to the muscles of mastication

V3

35

nerve both pass through the internal acoustic meatus

Vestibulochoclear and Facial

36

which innervates the muscles of mastication, passes through the foramen ovale.

Mandibular division of trigeminal V3

37

Damage to V3

hard to chew and sensation on lower jaw

38

Hoarseness could result from injury to

the recurrent branch of the vagus nerve (CN X).

39

CN X exits the skull through the

jugular foramen

40

) courses anteriorly through the submandibular triangle on its way to innervate the tongue.

hypoglossal nerve (CN XII)

41

When doing surgery near the submandibular gland, the surgeon would try to identify this nerve as to not damage it while removing the tumor.

Hypoglossal nerve XII

42

maxillary nerve is a branch (V2) of the trigeminal nerve (CN V) that exits the skull via

the foramen rotundum and enters the pterygopalatine fossa where it branches into the orbit and other areas of the midface

43

the facial vessels course through the submandibular triangle, the facial nerve

does not.

44

The facial nerve exits from the ________________ in the skull and passes through the ____________, at which point it branches into five major branches.

stylomastoid foramen
parotid gland

45

the mandibular nerve (V3) is a branch of the trigeminal nerve (CN V) that exits the skull via the

foramen ovale to enter the infratemporal fossa and branches extensively.

46

accessory nerve exits the skull base via the _________ and travels deep to the sternocleidomastoid muscle. It is not located near the submandibular gland.

jugular foramen

47

A 43-year-old patient sees his doctor because of loss of bitter and sour taste on the back 1/3 of his tongue and trouble swallowing. Identify the cranial nerve most likely to be injured in this patient

glossopharyngeal nerve

48

carries special sensory taste fibers from the posterior 1/3 of the tongue. When damaged, taste from the posterior 1/3 of the tongue is lost. Similarly, this nerve also contributes to the pharyngeal plexus, which can lead to impaired swallowing if this nerve is damaged

Glossophyarngeal nerve

49

is responsible for innervation of the superior oblique extraocular muscle

CN IV, or the trochlear nerve

50

provides motor innervation to most of the extraocular muscles of the eye, in addition to controlling constriction of the pupil and maintaining an open eyelid.

Oculomotor nerve III

51

nerve, provides sensory innervation to the lower lip, along the mandible, and the area anterior to the ear, coinciding with this patient’s loss of sensation.

CN V, or the trigeminal

52

Responsible for taste sensation for the anterior 2/3 of the tongue.

Chorda tympani of Facial nerve

53

damage to the facial nerve would cause

facial paralysis and taste impairment on the anterior 2/3 of the tongue

54

Hyperacusis would result from damage to

branch of the facial nerve: the nerve to the stapedius.
