1

what are the 3 main branches of the trigeminal nerve

ophthalmic branch
maxillary branch
mandibular branch

2

what are the lower molars innervated by

the mandibular branch of trigeminal nerve

3

what is cranial nerve 1

olfactory

4

what is cranial nerve 2

optic

5

what is cranial nerve 3

oculomotor

6

what is cranial nerve 4

trochlear

7

what is cranial nerve 5

trigeminal

8

what is cranial nerve 6

abducens

9

what is cranial nerve 7

facial nerve

10

what is cranial nerve 8

vestibulocochlear

11

what is cranial nerve 9

glossopharyngeal

12

what is cranial nerve 10

vagus

13

what is cranial nerve 11

spinal accessory

14

what is cranial nerve 12

hypoglossal

15

what division does the inferior alveolar nerve come from

mandibular branch of CN V

16

what does the inferior alveolar nerve give off anteriorly

the mental nerve

17

what does the mental nerve exit the mandible from

metal foramen

18

what does the mental nerve supply

chin and lower lip

19

what can often be accidentally anesthetized as well as the inferior alveolar nerve

lingual nerve

20

where does the inferior alveolar nerve supply to

lower central
does not cross the middle

21

where do we want to inject

not hitting the nerve
want to deposit next to the nerve on the bone

22

if patients feels that their lip has been hit what is most likely done

you have hit the nerve

23

what does hitting the inferior alveolar nerve do

the numbness may remain due to a temporary damage of the ID nerve

24

what is paraesthesia

an abnormal sensation typically tingling or picking (pins and needles)

25

why is paraesthesia a good sign if the ID nerve has been hit

the nerve has not been completely anesthetized

26

what is dysaesthesia

an abnormal unpleasant sensation felt when touched, caused by damage to the peripheral nerves

27

why should parents be warned when it comes to LA

lip cannot be felt
child may bite lip
can cause ulceration

28

why is the damage done to the ID nerve temporary

you have traumatized the nerve
so there is swelling pressing on the nerve
there is no complete dissection of the nerve so no permanent damage

29

what nerve is involved in the afferent (sensorial response) of the gag reflex

glossopharyngeal nerve

30

what nerves are involved in the motor response of the gag reflex

trigeminal
glossopharyngeal
vagus
accessory
hypoglossal
