Nerves of the Oral Cavity 11-1-16 Flashcards
Cranial Nerve V is the
trigeminal nerve
Cranial nerve VII is the
facial nerve
Cranial nerve IX is the
glossopharyngeal nerve
Cranial nerve XII is the
hypoglossal nerve
What are the 3 divisions of the trigeminal nerve (cranial nerve V)
- division I: ophthalmic (afferent)
- division II: maxillary (afferent)
- division III: mandibular (afferent and efferent)
The 2nd division (Maxillary nerve) of the trigeminal nerve has …. branches which are…
- 4
- Pterygopalatine
- Posterior Superior Alveolar
- Infraorbital
- Zygomatic
- Pterygopalatine
The first division (ophthalmic nerve) of the trigemincal nerve exits cranium via…
superior orbital fissure (sphenoid)
The ophthalmic nerve (division I of trigeminal/ CNV) innervates….(6)
- upper 1/3 of face
- eyeball
- superior eyelid
- nose
- maxillary sinus forehead
- scalp
The maxillary nerve (division II of trigeminal/CNV) exits via the foramen…. into the… space
- rotundum
- pterygopalatine
The nasopalatine branch of the pterygopalatine branch of the maxillary nerve (of CNV) enters palate through the… foramen
incisive (painful location for anes. for patient)
The posterior Superior Alveolar (PSA) branch of the pterygopalatine/maxillarydivisionII/CNV separates from the… nerve before its entry into the…. fissure
- maxillary
- infraorbital
The PSA enters the maxillae behind and above …. and innervates…
- 3rd molars through alveolar canals
- maxillary molars: pulps, ligaments, alveolar bone, facial gingiva
If you were extracting a maxillary 2nd molar, you would need to anesthetize … and …
PSA and greater palatine
The PSA innerv. the maxillary 3rd, 2nd and part of the 1st molar but NOT
mesiobuccal root on the 1st
The Infraorbital branch of CNV/maxillarydivisionII while in the … canal gives off… (which some patients do not have) which innervates premolar pulps and MB root of 1st molar and facial gingiva, bone and ligament.
- infraorbital
- middle superior alveolar
The infraorbital branch of the CNV/maxillary nerve gives rise to MSA and…. which innerv. anterior teeth (incisors/canines), facial gingiva and part of sinus
Anterior Superior Alveolar
The 3rd division of the trigeminal (CNV) is the …. nerve
Mandibular
The mandibular has 7 branches…
- auriclotemporal
- buccal**
- lingual**
- inferior alveolar**
- mylohyoid
- mental**
- incisive**
The mandibular nerve (of CNV) exits cranium via the foramen…
ovale
The greater palatine enters palate through the….
greater palatine foramen
The MSA and PSA enter through the…
lesser palatine foramen
The auriculotemporal branch of the mandibular nerve (of CNV) provides sensation to… and proprioception to…
- outer ear and skin of face anterior to ear
- TMJ
The buccal nerve (of the mandibular of CNV) goes through the… space to innerv. ….
- infratemporal space (btw heads of lateral pterygoid muscles
- buccal gingiva of molars and premolars( and buccal mucosa and skin of cheeks up to commissure)
The mandibular nerve goes lateral to…
ramus to cheek and mucosa/gingiva next to molars
