Maxillary Division Flashcards
Where does the maxillary division enter the pterygopalatine fossa
Through the foramen rotundum
Is the maxillary division sensory, motor, or mixed
Sensory only
What are the 4 branches of the maxillary division
Middle meningeal nerve, Zygomatic nerve, Infraorbital nerve, and Ganglionic Branches
What nerve is given off before the maxillary division leaves the foramen rotundum
Middle meningeal n.
Where does the zygomatic nerve enter the orbit
Through the infraorbital fissure
The zygomatic n. gives off a communicating branch which carries what kind of fibers from the pterygopalatine ganglion to the lacrimal gland
Postganglionic Parasympathetic fibers
The zygomatic n. gives rise to what n. that supplies skin over the temple
Zygomaticotemporal n.
What n. supplies the skin over the cheek
Zygomaticofacial
The ganglionic branches carry what kind of information
Sensory
Where do the ganglionic branches carry info from
The upper pharynx, nasal cavity, and palate through the pterygopalatine ganglion to the maxillary division
The infraorbital n. travels through the infraorbital fissure and canal to supply what
The lower eyelid, skin over the upper jaw, and maxillary sinus
Before entering the infraorbital canal, what does the infraorbital n. give off
The posterior, middle, and anterior superior alveolar nerves that carry sensory info from the teeth
Where is the superior dental plexus found
Just above the alveoli
Fibers from what branch are used to distribute postganglionic parasympathetic fibers from the pterygopalatine ganglion
Branches of the maxillary division of the trigeminal nerve (sensory)
How do preganglionic parasympathetic reach the pterygopalatine ganglion from the facial n.
By way of the Greater petrosal n.
