Maxillary Division Flashcards
How does the maxillary division enter the pterygopalatine fossa (through which foramen)?
Foramen Rotundum
What is the other name for the foramen rotundum?
round foramen
What kind of fibers are carried by the maxillary division?
sensory only
What skin is supplied by the maxillary division?
skin between the eyes and mouth, over the cheeks and temples
What mucosa is supplied by the maxillary division?
mucosa lining the maxillary sinuses, nasal conchae, palate and gingiva
What are the four branches of the Maxillary division?
Middle meningeal, Zygomatic, Ganglionic branches, and the Infraorbital nerves (while studying the maxillary division “My Zzzs Get Interrupted”)
What nerve is given off before the maxillary division exits the round foramen?
Middle meningeal nerve
What dura is supplied by the middle meningeal nerve of the maxillary division?
meninges of the middle cranial fossa
Where does the zygomatic nerve enter the orbit?
inferior orbital fissure
What are the three brances of the zygomatic nerve?
a comunicating branch, zygomaticotemporal nerve, and zygomaticofacial nerve
What kind of fibers are carried by the communicating branch given off of zygomatic nerve?
postganglionic parasympathetic fibers
Where are the fibers which are carried by the communicating branch given off of the zygomatic nerve from and to?
the pterygopalatine ganglion to the lacimal gland/nerve
What nerve supplies the skin over the temple?
the zygomaticotemporal nerve of the zygomatic nerve of the maxillary division of the trigeminal nerve
What nerve supplies the skin over the cheek?
The zygomaticofacial nerve of the zygomatic nerve of the maxillary division of the trigeminal nerve
How many ganglionic branches are given off of the maxillary division?
two or three
What do the ganglionic branches of the maxillary division supply sensory info?
from the upper pharynx, nasal cavity and palate to the maxillary division
What ganglion do theganglionic branches of the maxillary division travel through?
pterygopalatine ganglion
What nerve of the maxillary division travels through the infraorbital fissure and infraorbital canal?
infraorbital nerve
What nerves are given off of the infraorbital nerve?
posterior superior, middle superior, and anterior superior alveolar nerves
In addition to carrying info from the teeth, what other area(s) are supplied by the infraorbital nerve?
lower eyelid and maxillary sinus
What plexus can be found just above the alveoli?
superior dental plexus
Which branch of the infraorbital nerve supplies the premolars?
middle superior alveolar nerve
Which branch of the infraorbital nerve supplies the incisors and canines?
anterior superior alveolar nerve
Which branch of the infraorbital nerve supplies the molars?
posterior superior alveolar nerve
