3

what bones make up the roof

nasal, frontal, ethmoid, sphenoid

4

what are the two divisions of the trigeminal nerve -Cr5

ophthalmic - V1
maxillary- v2

sensory and parasympathetic fibres

what is the arterial supply of the ant sup part of the lateral wall

ant post ethmoidal branches of the ophthalmic artery plus the facial artery

12

what is the arterial supply of the post inf part of the lateral wall

greater palatine and sphenopalatine branches of the maxillary artery

13

what does a dehiscent palatine canal lead to
