What are the ten communications of the 'Pterygopalatine Fossa'?

 

[osli]

oral cavity
nasal cavity
foramen lacerum
orbit
infratemporal fossa
nasopharynx
middle cranial fossa

Or do you mean the passageways?
pterygomaxillary fissure
foramen rotundum
pterygoid canal
palatinovaginal canal
sphenopalatine foramen
inferior orbital fissure
alveolar foramen
greater/lesser palatine foramen/canals
erm... pharyngeal canal?

Great review... and way to get answers for an anatomy question... but I'll bite. Perhaps the OP was referring to nerves?

pharyngeal nerve (facial, trigeminal) via palatovaginal canal
greater palatine nerve via greater palatine foramen
lesser palatine nerve via lesser palatine foramen
nasopalatine nerve via sphenopalatine foramen
Trigeminal maxillary division+facial postganglion via inferior orbital fissure

I figured I'd clarify nerve components, and forgot to include the vidian nerve.

pharyngeal nerve (facial, trigeminal maxillary division) via palatovaginal canal (2)
greater palatine nerve (trigeminal maxillary division) via greater palatine foramen (1)
lesser palatine nerve (facial postganglionic, trigeminal maxillary division) via lesser palatine foramen (2)
nasopalatine nerve (trigeminal maxillary division, facial postganglionic) via sphenopalatine foramen (2)
Trigeminal maxillary division+facial postganglion via inferior orbital fissure (2)

Vidian nerve (facial) via pterygoid canal (1)

Leading to a grand total of 10 nerve fiber connections.

Wow you guys really need to stop this thread right now. It's incredibly lame.
