Head & Neck – Bones and foramina
34.
Which bone makes up part of the roof of the orbit p959 NM
a.
Sphenoid
T - lateral part
b.
Maxilla
F – floor
c.
Lacrimal
F - Medial wall
d.
Ethmoid
F - medial wall
e.
Temporal
F - Not involved
35.
What runs through the foramen spinosum p900NM
a.
ICA
F – lacerum
b.
Maxillary br trigeminal
F - Foramen rotundum
c.
Mandibular br trigeminal
F - Foramen ovale
d.
Middle meningeal artery
T - Meningeal nerve
36.
Which vessel supplies a branch which passes through
the foramen spinosum
a.
maxillary artery
T - middle meningeal A from Maxillary A and meningeal branch of CNV3
p900 NM
37.
What exits the stylomastoid foramen
a.
middle meningeal artery
F
b.
accessory nerve
F
c.
facial nerve
T
d.
artery to stapedius
F
e.
hypoglossal nerve
F
38.
Which does not travel through the jugular foramen
a.
hypoglossal nerve
T - hypoglossal canal/foramen
b.
accessory nerve
F
c.
inferior petrosal sinus
F
d.
glossopharyngeal nerve
F
e.
vagus nerve
F
f.
jugular vein
F
39.
A fracture through the roof of the maxillary sinus might
result in sensory loss to the
a.
tympanic membrane
F
b.
lacrimal gland
F
c.
upper molar teeth
T
d.
upper incisors and canine teeth
F
e.
skin overlying the zygomatic bone
F
40.
A fracture through the floor of the maxillary sinus may cause
a.
Loss of sensation of the upper molars
T - p1022 NM
b.
Loss of sensation of the canines and incisors
F - MAYBE YES IF they mean upper via disruption to maxillary nerve CNV2
which supplies the superior alveolar nerves which go to all top teeth
(front incisors supplied by infraorbital nerve which becomes an alveolar n
which is also a branch of CNV2) But if they mean upper plus lower;
Can’t be this one since lower jaw teeth are innervated by inf alveolar nerve
from mandibular nerve CNV3
41.
Which of the following enters into the inferior meatus of

b.
ethmoidal sinus
F - superior meatus
c.
maxillary sinus
F
d.
nasolacrimal duct
T – p1015 NM
e.
auditory tube
F
f.
inferior alveolar nerve
F
