mandibular nerve Flashcards
mandibular n passes through
foramen ovale
motor branches supply
- all mm of mastication
- mylohyoid and anterior belly of digastric
- tensor tympani m
- tensor veli palatini m
meningeal n is also called
nervus spinosus
companion of meningeal n
middle meningeal a
meningeal n passes through what foramen
foramen spinosum
what does meningeal n supply
dura mater of mcf
mastoid air cells (middle ear)
n to medial ptergoid m branches supply
- tensor veli palatini (aka soft palate)
2. tensor tympani m (middle ear)
messeteric n path
passes laterally over the lateral pterygoid m and through the mandibular notch
masseteric n supplies
- masseter m
2. anterior portion of tmj
buccal n is sensory or motor
sensory
buccal n path
passes between two heads of lateral pterygoid and descends to anterior margin of ramus
buccal n supplies
- skin of cheek
- oral mucosa of cheek
- BUCCAL GINGIVA OF LOWER MOLARS
mylohyoid n is a branch of what n
inferior alveolar n
path of auriculotemporal n
- around middle meningeal a
- medial to upper head of later pterygoid
- between sphenomandibular ligament and neck of condyle
- ascends between tmj and eam
temporal branches of AT n supply
skin over lateral aspect of scalp
auricular branches of AT n supply
external ear (auricle, EAM, tympanic membrane)
articular branches of AT n supply
TMJ and parotid gland
inferior alveolar n passes through what and enters through what
passes through mandibular canal by entering the mandibular foramen
what does the inferior alveolar n supply
- molar teeth
- 2nd premolar tooth
2 terminal branches of inferior alveolar n
- incisive n
2. mental n
incisive n supplies
- incisors
- canine
- 1st premolar
mental n supplies
- lower lip
- chin
- gingiva of central incisor to 2nd premolar
lingual n provides sensory information to what
- anterior 2/3 of tongue
- floor of the mouth
- MANDIBULAR LINGUAL GINGIVA
two branches of cranial nerves that join branches of mandibular nerve
- chorda tympani
2. lesser petrosal n
chorda tympani is a branch of __ and joins with ___
branch of facial n, joins with lingual n
lesser petrosal n is a branch of __ and joins with __
branch of glossopharyngeal n, joins with auriculotemporal n
taste and sensory info to anterior 2/3 of tongue
- taste: chorda tympani
- sensory: lingual n
parasymp fibers in chorda tympani n travel with lingual n to floor of the mouth to
synapse within the submandibular ganglion
after synapsing with submand ganglion, postganglionic parasympathetic fibers supply
- submandibular and sublingual glands
- minor glands of floor of the mouth
otic ganglion receives fibers from
- sensory fibers
- symp fibers
- parasymp fibers
sensory fibers of otic ganglion
- arise from the stem of CN V3
- pass through ganglion WITHOUT synapsing
sympathetic fibers of otic ganglion
- arise from perivascular plexus of middle meningeal a
- pass through ganglion WITHOUT synapsing
parasymp fibers of otic ganglion
- arise from route originating from lesser petrosal n (CN 9)
- THEY DO SYNAPSE in ganglion
parasymp pathway of otic ganglion
- CN9 pass jugular foramen
- tympanic n branches off and re enters skull
- tympanic plexus of nerves (middle ear)
- leaves as lesser petrosal n and synapses at otic ganglion
major sensory innervation to parotid gland
auriculotemporal n
major motor innervation to parotid gland
lesser petrosal n
order of mandibular nerve branches back to front
- meningeal
- auriculotemporal
- IAN
- lingual
- n to medial pterygoid
- masseteric
- buccal
- deep temporal
