trigeminal nerve 1

Question 1

divisions of trigeminal nerve and type of info it sends

Answer 1

ophthalmic (CN V1) –> sensory info
maxillary (CN V2) –> sensory info
mandibular (CN V3) –> sensory and motor info

Question 2

where does the divisions of the trigeminal nerve exit the crainum

Answer 2

ophthalmic (CN V1) –> SOF
maxillary (CN V2) –> foramen rotudum
mandibular (CN V3) –> foramen ovale

Question 3

what type of sensory info does the trigeminal nerve divisions send

Answer 3

skin on face

Question 4

what info does the mandibular division of trigeminal nerve (CN V3) send

Answer 4

sensation from:
- side of head
- skin of face over mandible
- lower lip
- mandibular teeth
- temporomandibular joint
- muscosa (Floor) of mouth
- anterior 2/3 of tongue

Question 5

branches of mandibular division (CN V3) after passing through the foramen ovale

Answer 5

• auriculotemporal nerve
• inferior alveolar nerve
• buccal nerve
• lingual nerve
• muscular branches (masseter, temporalis, medial/lateral pterygoid)
• through mandibular foramen –> branch to inferior dental plexus
  through mental foramen terminates as mental nerve

Question 6

motor branches of mandibular division of trigeminal nerve

Answer 6

• masseter
• temporalis
• medial pterygoid
• lateral pterygoid

Question 7

pathway of branches of mandibular division (just notes I had)

Answer 7

• auricultemporal –> medial to mandible to head posteriorly
• lingual –> anterior to oral cavity, sensation to tongue and roof of mouth
• mental nerve –> exits through mental foramen, sensation to lower lip/teeth and chin
• buccal nerve –> anterior to oral cavity, cutaneous sensation of cheek
