pterygopalatine fossa Flashcards
what fossa is lateral to the pterygopalatine fossa
infratemporal fossa
medial wall of the pterygopalatine fossa
palatine bone with the sphenopalatine foramen
the hub for nereons and arteries for the middle face
pterygopalatine fossa
what ganglion is found int eh pterygopalatine fossa
ptergopalatine ganglion (CN VII)
what does the pteryogpalatine ganglion consist of
CN VII mainly
attached to V2 by 2 short pterygopalatine nerves
receives (Vidian) n of pterygoid canal
both sympa and parasympa fibers
what fibers synapse in the pterygopalatine ganglion
parasympa fibers
openings of the pterygopalatine fossa
inferior-orbital fissure sphenopalatine foramen pterygomaxillary fissure foramen rotundum pterygoid canal palatovaginal canal palatine canal
the sphenopalatine foramen opens into
the nasal cavity
the inferior orbital fissure opens into
the flor of the orbit
the pterygomaxillary fissure opens into
infratemporal fossa
Foramen rotundum opens into
the middle cranial fossa
the pterygoid canal opens into
the cranial cavity
the palatovaginal canal opens into
the nasopharynx
the palatine canal opens into
the roof of the oral cavity
lateral openings of pterygopalatine fossa
pterygomaxillary fissure
roof openings of the pterygopalatine fossa
infraorbital fissure
medial openings of the pterygopalatine fossa
sphenopalatine foramen
inferior openings of the pterygopalatine fossa
palatine canal
posterior openings of the pterygopalatine fossa
foramen rotundum
pterygoid canal
pharyngeal canal
what arteries pass through the pterygomaxillary fissure
maxillary artery infra-orbital A sphenopalatine A artery of the pharyngeal canal pharyngeal artery greater and lesser palatine artery posterior superior alveolar artery
what veins pass through the pterygomaxillary fissure
veins of the same name
also emissaries that drain into the ptygoid plexus
location of the sphenopalatine foramen
anterior and inferior to sphenoid sinus
what passes through sphenopalatine foramen
sphenopalatine artery
Nasopalatine N (V2)
Posterior lateral Nasal N (V2)
what goes through foramen rotundum
Maxillary Nerve (V2)
where is the inferior orbital fissure
posterior/inferior aspect of the orbit
what passes through the inferior orbital fissure
infraorbital nn (V2) zygomatic nn (V2) accompanying aa
infraorbitals n conintues where after passing through inferior orbital fissure
infraorbital foramen to face
zygomatic nerves sends what branches in orbit leadinng to the face
zygomaticotemporal n
zygomaticofacial n
parasympa for lacrimal gland comes from
zygomatic branches of V2 that communicate with V1
what does the pterygoid canal connect
connects foramen lacerum and pterygopalatine fossa and sphenopalatine foramen
what serves as one psoterior opening of the pterygopalatine fossa
pterygoid canal
what passes through the pterygoid canal
Vidian N of pterygoid canal
pterygoid branch of maxillary a
location of the pharyngeal canal
superior and lateral to alae of vomer bone
anterior and medial to pterygoid canal
what does the pharyngeal canal transmit
pharyngeal N (CN V2) pharyngeal branch of maxillary a
travel of the palatine canal
runs vertically lateral to perpendicular plate of palatine bone
what passes through the palatine canal
greater and lesser palatine Nn (CN V2)
descending palatine a
greater and lesser palatine aa, runngint with assocated nerve
greater and lesser palatine aa emerge where
through greater and lesser palatine foramen
vidian N supply
lacrimal, nasal, palatal glands
