Pterygopalatine Fossa Flashcards
Pterygopalatine fossa is located between these bones
Sphenoid and palatine bones
Circular hole to the nasal cavity that is the deepest space of the pterygopalatine fossa
Sphenopalatine foramen
Superficial space that is a passage between infratemporal fossa and pterygopalatine fossa
Pterygomaxillary fissure
Blood supply to pterygopalatine fossa
Maxillary artery
Maxillary veins drains into this
Internal jugular vein
Only structure that passes through the foramen rotundum to enter the pterygopalatine fossa
CN V2 maxillary nerve
Nerve that passes through the infraorbital groove and canal when it gives off superior alveolar nerve branches
Infraorbital nerve
Terminal part of the infraorbital nerve, artery, and vein pass through this
Infraorbital foramen
Nerve that passes through the infraorbital groove and canal when it gives off superior alveolar nerve branches
Infraorbital nerve
Neurovascular structures that emerge from the pterygopalatine fossa to enter the nasal cavity by passing through the sphenopalatine foramen (3)
Sphenopalatine artery, vein, and CN V2 nerve branches
Structures that pass through the sphenopalatine foramen (3)
Sphenopalatine artery, vein, and CN V2 nerve branches
Artery/vein that bifurcates into the greater and lesser palatine artery/vein
Descending palatine
Nerve, artery, and vein that supply the tissues of the hard palate
Greater palatine
Nerve, artery, and vein that supply the tissues of the soft palate
Lesser palatine
Structures that emerge from the pterygopalatine fossa and enter the palatine canal
Greater and lesser palatine nerves, descending palatine artery and vein
