Flashcards in Quiz 2: Maxillary and Maxillary Div. Deck (57)
The maxillary division of C.N V enters what location through the foramen rotundum?
What type of signal is relayed in the maxillary division of trigeminal?
Where does the maxillary division carry sensation from?
From the skin between the eyes and mouth, over the cheeks and temples, also from the mucosa lining the maxillary sinuses, nasal conchae, palate and gingiva
What are the four branches of the maxillary division?
Middle meningeal nerve, zygomatic nerve, ganglionic branches (2 or 3) and the infraorbital nerve
T/F: The middle meningeal nerve is given off after the division exits the foramen rotundum (round foramen).
False, it is given off before the middle meningeal nerve exists the foramen rotundum.
What does the middle meningeal nerve supply?
The Meninges (dura) of the middle cranial fossa.
Where does the zygomatic nerve enter the orbit?
Through the inferior orbital fissure
What branch(es) does the zygomatic nerve give off?
It gives off a communicating branch.
What type of fibers does the communicating branch carry? Where does it travel?
Postganglionic parasympathetic fibers from the pterygopalatine ganglion to the lacrimal gland
What nerves does the zygomatic nerve give rise to?
Zygomaticofacial and Zygomaticotemporal
What does the zygomaticotemporal nerve supply?
Skin over the temple
What does the zygomaticofacial nerve supply?
Skin over the cheek.
What type of information is carried in the ganglionic branches?
What do the ganglionic branches supply?
Upper pharynx, nasal cavity, and palate --> through the pterygopalatine ganglion --> to the maxillary division.
What does the infraorbital nerve supply?
Lower eyelid, skin over the upper jaw, and maxillary sinus
Before entering the infraorbital canal, what nerves are given off by the infraorbital nerve?
The posterior, middle and anterior superior alveolar nerves.
What information is carried by the posterior, middle and anterior superior alveolar nerves?
1. Post: Molars
2. Middle: Premolars
3. Ant: Incisors
*Not sure what carries sensory info from canines.
The ___________ _________ _________ is found just above the alveoli.
Superior dental plexus
Branches of the maxillary division of the trigeminal are used to distribute postganglionic parasympathetic fibers from the ____________ __________.
Preganglionic parasympathetic fibers reach the pterygopalatine ganglion from the facial nerve by way of the _______ _______ nerve.
Postganglionic sympathetic fibers from the ________ ________ ________ pass through the pterygopalatine ganglion.
Superior cervical ganglion
What also passes through the pterygopalatine ganglion?
What does the mandibular division exit the cranial vault as?
1.) Large sensory root
2.) Small motor root
Where does the mandibular division carry sensory info from?
Skin over the mandible, posterior cheek, and posterior temple. Also, from the mucosa of the lower oral cavity and cheeks.
What muscles are innervated with motor fibers by the mandibular division?
Muscles of Mastication
2.) Lateral Pterygoid
3.) Medial Pterygoid
5.) Anterior Belly of Digastric
6.) Tensor Veli Palatine
7.) Tensor Tympani
What two branches are given off in the infratemporal fossa?
Recurrent Meningeal Branch and Medial Pterygoid Nerve
What does the recurrent meningeal branch re-enter the cranium through?
The foramen spinosum
What type of information is carried in the recurrent meningeal branch?
Where is information carried from in the recurrent meningeal branch?
Dura of the middle cranial fossa, anterior cranial fossa and calvarium.
