DEN 110 NERVES TEST QUESTION & ANSWERS
What are the three divisions of the trigeminal nerve?
Ophthalmic Nerve (V1)
Maxillary Nerve (V2)
Mandibular (V3) - Answers -What is the name of the ganglion connected with the
divisions of the trigeminal nerve into three parts?
Trigeminal ganglion (aka Semilunar ganglion or Gasserian ganglion)
List the three branches or divisions of the maxillary nerve.
Infraorbital
Zygomatic
pterygopalatine - Answers -Which two branches of the maxillary nerve supply all the
maxillary teeth?
Infraorbital and posterior superior alveolar
Which three individual nerves serve the maxillary sinus?
Posterior Superior Alveolar
Anterior Superior Alveolar
Middle Superior Alveolar - Answers -What teeth do branches of the infraorbital
innervate?
PSA- maxillary molars
MSA-maxillary premolars and MB root of maxillary first molar
ASA-maxillary canines and incisors
You could name two nerves that serve the maxillary anterior gingiva. One passes
through the maxillary sinus first.
It is the ASA(anterior superior alveolar).
The other nerve passes through the infraorbital foramen.
It is the infraorbital nerve - Answers -What branch of the maxillary nerve passes
through the maxillary tuberosity?
Posterior Superior Alveolar Nerve
What two nerves are associated with innervations of the maxillary first molar? What root
does each nerve serve?
, If present, the middle superior alveolar nerve innervates the mesiobuccal root of the
maxillary first molar. The posterior superior alveolar nerve innervates the first molar's
lingual root and the distobuccal root. - Answers -What nerve innervates the maxillary
buccal gingiva in the molar region? The premolar region? The anterior region?
The posterior superior alveolar nerve innervates the maxillary buccal gingiva in the
molar region. If present, the middle superior alveolar innervates the buccal gingiva in
the premolar region. The anterior superior alveolar innervates the facial gingiva of the
anterior region.
Through what opening does the ophthalmic branch pass to get to the orbit?
The ophthalmic branch exits from the superior orbital fissure. - Answers -What general
areas does the ophthalmic nerve innervate?
The ophthalmic nerve innervates the orbit and anterior scalp.
What fossa is connected with the maxillary division of the trigeminal? Where is this
fossa located?
Ptyergopalatine fossa. This fossa is located between the maxillary bone and pterygoid
process of sphenoid bone. - Answers -What three main branches (that we are studying)
come off the pterygopalatine ganglion? What is the name of this group of nerves?
1- Descending palatine
(Greater palatine nerve and Lesser palatine nerve)
2- Sphenopalatine nerve
(Nasopalatine nerve)
3- Pharyngeal nerve
(Pterygopalatine nerve group)
What nerve goes through the greater palatine foramen?
Greater palatine nerve - Answers -What nerve goes through the incisive foramen?
(Where is the incisive foramen?)
Nasopalatine nerve. The incisive foramen is located directly behind and between the
maxillary central incisors.
What nerve goes through the lesser palatine foramen?
The lesser palatine nerve - Answers -What nerves innervate the hard palate?
Greater palatine and Nasopalatine
What are the three divisions of the trigeminal nerve?
