|
The pterygopalatine ganglion contains what type of neuronal cell bodies?
|
Post-ganglionic parasympathetic neuronal cell bodies
|
|
|
The pterygopalatine ganglion is suspended by 2 pterygopalatine nn from where?
|
The maxillary nerve
|
|
|
The space between the lateral pterygoid plate of the sphenoid bone and the maxilla is called?
|
The pterygomaxillary fissure
|
|
|
What are the spacial definitions of the the pterygopalatine fossa?
|
It is a triangular space between the pterygoid plate of the sphenoid bone - the perpendicular plate of the palatine bone(medial wall) and the pterygomaxillary fissure(lateral wall).
|
|
|
The hole just medial to the pterygomaxillary fissure is called?
|
The sphenopalatine foramen.
|
|
|
Going clockwise, superioanterior to posterior inferior, what are the openings associated with the pterygopalatine fossa?
|
1. Inferior orbital fissure
2. sphenopalatine foramen 3. palatovaginal canal (pharyngeal canal) 4. foramen rotundum 5. pterygoid canal 6. palatine canal 7. pterygomaxillary fissure |
|
|
Anterior to the pterygopalatine fossa, you can enter the orbit through what opening?
|
Inferior orbital fissure
|
|
|
Medially you can enter the nasal cavity through what opening?
|
sphenopalatine foramen
|
|
|
Laterally you can enter the infratemporal fossa through what space?
|
The pterygomaxillary fissure
|
|
|
Inferiorly you can enter the palate through what opening?
|
The palatine canal
|
|
|
What nerve enters the pterygopalatine fossa from the foramen rotundum?
|
The maxillary n (V2)
|
|
|
The what allows passage of the vidian n into the pterygopalatine fossa?
|
The pterygoid canal
|
|
|
Posteriorly, you can enter the pharyngeal canal from the PtP through what opening?
|
The pharyngeal canal. The pharyngeal n travels through this opening.
|
|
|
Before branches of V2 enter the orbit through the inferior orbital fissure, it gives off what branch that travels through the alveolar foramen?
|
The posterior superior alveolar n
|
|
|
What 4 branches of the maxillary nerve enter the inferior orbital fissure?
|
1. Infraorbital n
2. Zygomatic n 3. 2 orbital branches |
|
|
What nerve exits the sphenopalatine foramen from the PtP?
|
The nasal nerves
|
|
|
What nerve exits inferiorly from the pterygopalatine ganglion?
|
The palatine nerves
|
|
|
The postganglionic parasympathetic fibers travel with what structures to reach the mucosal glands and vessels of the palate, nasal cavity, pharynx and lacrimal gland?
|
The sensory branches of the pterygopalatine ganglion
|
|
|
What are the two branches of the zygomatic n?
|
1. Zygomaticotemporal n (communicating branch comes off this n to give parasympathetic and sympathetic fibers to the lacrimal gland)
2. Zygomaticofacial n |
|
|
What structures does the posterior superior alveolar n supply?
|
1. maxillary sinus
2. Last three maxillary molars |
|
|
What 3 nerves off V2 supply the maxillary sinus?
|
1. posterior superior alveolar
2. middle superior alveolar 3. anterior superior alveolar |
|
|
What are the 3 terminal branches of the maxillary n?
|
1. Inferior palpebral brs (to skin and conjunctiva of lower eyelid)
2. External nasal brs to skin of lateral nose 3. Superior labial brs to skin and mucous membrane of upper lip |
|
|
The pharyngeal nerve provides sensory and autonomic fibers to what structure?
|
The pharynx
|
|
|
The lesser palatine nerve supplies what structure with sensory and autonomic fibers?
|
The soft palate. it leaves the pterygopalatine ganglion heads through the palatine canal and takes a turn posteriorly to innervate the soft palate.
|
|
|
The greater petrosal nerve innervates what structures?
|
The hard palate
|
|
|
The maxillary (V2) dermatome is supplied by 3 nerves. What are they?
|
From superior to inferior:
1. Zygomaticotemporal n 2. Zygomaticofacial n 3. Infraorbital n |
