Maxillary division of CN V Flashcards
What is the exit pathway?
It exits the middle cranial fossa through the foramen rotundum and enter the pterygopalatine fossa.
The PP fossa sends branches to where?
the orbit, nose and mouth
The maxillary division has what branches?
the infraorbital and the zygomatic
How does the infraorbital enter the orbit?
through the IOF
infraorbital nerve travels along what? where?
travels along the floor of the orbit in the infraorbital groove and canal
infraorbital nerve provides sensory to what?
skin of upper lip, skin of soft part of cheek, lower eyelid and skin on lateral side of nose
What branches does the infraorbital nerve give of?
- anterior superior alveolar
- Middle superior alveolar
- greater palatine nerve
- lesser palatine nerve
- posterior lateral nasal wall
- pharyngeal nerve
Zygomatic nerve enters the orbit via what?
inferior orbital fissure (IOF)
Zygomatic nerve passes along what?
lateral wall of orbit
Zygomatic nerve divides into what branches?
zygomaticofacial nerve and zygomaticotemporal
zygomaticofacial nerve provides sensory to what?
skin on bony prominence of the cheek
zygomaticotemporal nerve provides sensory to what?
skin in area of the pterion and scalp
The greater palatine emerges through what? It is sensory to what?
Through the palatine foramen.
sensory to anterior part of hard palate
the lesser palatine foramen passes through what? It provides sensory to what?
passes through lesser palatine foramen to emerge onto plate.
sensory to: posterior part of hard palate and all of the soft palate
The posterior lateral nasal nerve enters through what? It provides sensory to what?
