Pterygopalatine fossa

?
what are the symptoms of hay fever?
acute inflammation of nasal mucosa:dilated blood vesselssneezing & stuffy, runny nose,watery eyes,allergy to pollen,activation of (pterygopalatine ganglion)-nasal glands secrete mucus,lacrimal gland produces tears

where is the pterygopalatine fossa located: beneath, anterior, posterior, medial, lateral
beneath the apex of the orbital cone, anterior to the pterygoid process of the sphenoid bone, posterior to the maxilla- pterygoid plate,medial to the infratemporal fossa, lateral to the postero-superior part of the lateral wall of the nasal cavity

pterygopalatine fossa communicates with ...and via what
the orbit via inferior orbital fissure (anteriorly) the middle cranial fossa via foramen rotundum & pterygoid canal (posteriorly) the infratemporal fossa via pterygomaxillary fissure (laterally) the nasal cavity via sphenopalatine foramen (medially
