max n and PP ganglion Flashcards
maxillary n is sensory or motor
only sensory
max n originates from
trigeminal ganglion in MCF
max n enters PP fossa through
foramen rotundum
branches of max n
- middle meningeal
- zygomatic
- posterior superior alveolar
- infraorbital
- ganglionic branches
ganglionic branches
- orbital branches
- palatine nn
- nasal nn
- pharyngeal n
branches of infraorbital n
anterior and middle superior alveolar nn
middle meningeal n supplies
meninges of MCF
zygomatic n enters orbit via
inferior orbital fissure
zygomatic n branches
- zygomaticotemporal n
- zygomaticofacial n
zygomaticotemporal n supplies
scalp over the temple
zygomaticofacial n supplies
skin on the prominence of the cheek (zygomatic region)
posterior superior alveolar n supplies
- max molar teeth (EXCEPT MB root of 1st molar)
- mucosal lining of max sinus
- buccal gingiva of max molars
infraorbital n is the anterior continuation of
maxillary n
infra orbital n exits the fossa via
inferior orbital fissure
inferior orbital fissure is formed by what two bones
greater wing of sphenoid and maxilla
inferior orbital fissure allows for communication with
- orbit and PP fossa
- orbit and IT fossa
middle superior alveolar n supplies
- premolar teeth (EXCEPT MB root of 1st molar)
- mucosal lining of max sinus
- vestibular gingiva of max premolars
what nerves supply mucosal lining of max sinus
-posterior, middle, and anterior superior alveolar n
anterior superior alveolar n supplies
- incisors and canine teeth
- mucosal lining of max sinus
- vestibular gingiva of max incisors and canine
- lateral wall near anterior end of inferior nasal concha
branches of infraorbital n
- lateral nasal
- inferior palpebral
- superior labial
lateral nasal branch
external branch: skin over lateral aspect of external nose
internal branch: skin over vestibule and antero-inferior aspect of nasal septum
inferior palpebral branch
skin of lower eyelid
superior labial branch
skin over upper lip and related oral mucosa
nerve of pterygoid canal is formed by
greater petrosal n (CN7) and deep petrosal n (internal carotid plexus)
greater petrosal n (CN7) supplies
- mucous glands in nasal cavity
- minor salivary glands in upper half of oral cavity (hard and soft palate, superior portion of pharynx)
- lacrimal gland
deep petrosal n fibers originate in
superior cervical sympathetic ganglion
deep petrosal supplies
blood vessels of upper and middle facial region
greater petrosal n fiber type
preganglionic parasymp
deep petrosal n fiber type
post ganglionic sympathetic
incoming fibers of PP ganglion
-sensory branches (from max n)
-sympathetic branches (from deep petrosal n)
-parasymp (from greater petrosal n)
NOTE: deep and greater petrosal nn form the n to pterygoid canal before synapsing on PP ganglion
orbital branches supply
- periosteum of orbit
- sphenoidal and ethmoidal sinuses
nasopalatine n (branch of nasal branches) path
passes through incisive canal and foramen to enter hard palate
nasopalatine n supplies
- palatal mucosa, gingiva, and glands from max canine to central incisor
- nasal branch: nasal septum
greater palatine n supplies
-palatal mucosa, gingiva, and glands from max premolars to molars
lesser palatine n supplies
mucosa and glands of soft palate
pharyngeal n supplies
mucosa and glands of nasopharynx
