Where is Infratemporal fossa located?

What structures does Sphenopalatine fossa communicate with?
medially: communicates with the nasal cavity via the sphenopalatine foramen, which transmits the sphenopalatine artery, the nasopalatine nerve and the posterior superior nasal nerves. laterally: communicates with the masticator space (or infratemporal fossa) via the pterygomaxillary fissure.
What passes through the Infratemporal fossa?
