the maxillary division (V2) exits the vault through what opening? It then enters what fossa?

foramen rotundum

pterygopalatine fossa

is maxillary division motor or sensory

sensory

where does the maxillary division carry sensory information from

skin between eyes and mouth, over cheeks and temples

mucosa lining maxillary sinus, nasal conchae, palate, gingiva

what are the branches of the maxillary division

meningeal (middle meningeal)

zygomatic

ganglion branches

infraorbital

the middle meningeal nerve is a branch of the maxillary division that is given off (before or after) the branch passes through the foramen rotundum

before

what does the middle meningeal nerve supply?

meninges of middle cranial fossa

the zygomatic nerve of the maxillary division travels from the ____ fossa and enters the orbit through what opening?

pterygopalatine, inferior orbital fissure

what are the branches of the zygomatic nerve

communicating branch

zygomaticotemporal nerve

zygomaticofacial nerve

the communicating branch of the zygomatic nerve carries _____ fibers from the ____ ganglion to the _____ gland?

what CN is the pterygopalatine ganglion associated with

CN 7

what does the zygomaticotemporal nerve supply

skin over temple

what does the zygomaticofacial nerve supply

skin over cheek

how many ganglionic branches of the maxillary division are there? where do they bring sensory information from?

2 or 3

upper pharynx, nasal cavity, palate

the ganglionic branches travel to the maxillary division through the _____ ganglion

pterygopalatine

through what opening does the infraorbital nerve enter the orbit? what opening does it exit through?

inferior orbital fissure

infraorbital canal

what does the infraorbital nerve supply

skin between lower eyelid and upper lip, maxillary sinus

what nerves does the infraorbital nerve give rise to

posterior superior alveolar nerve

middle superior alveolar nerve

anterior superior alveolar nerve

which branch of the infraorbital nerve supplies the molars

posterior superior alveolar nerve

what does the middle superior alveolar nerve supply

premolars

what does the anterior superior alveolar nerve supply

incisors

fibers of the pterygopalatine ganglion communicate with branches of which division before reaching their final destination?

maxillary

preganglionic parasympathetic fibers are carried to the pterygopalatine ganglion by what nerve?

greater petrosal nerve

what are the fibers of the pterygopalatine ganglion which communicate with branches of the maxillary division

- postganglionic parasympathetics

- postganglionic sympathetics from superior cervical ganglion which pass through the ganglion

- sensory fibers that pass through the ganglion
