Pterygopalatine
Definition:
(a.) Of or pertaining to the pterygoid processes and the palatine bones.
Example Sentences:
(1) After injection of WGA-HRP into the trigeminal ganglion, ganglion cell somata in the superior cervical and the pterygopalatine ganglion were labelled.

(3) A superior salivary nucleus, a root, pterygopalatine, submandibular, sublingual and auricular (in man) parasympathetic ganglia of the head, peripheral branches.
(4) An orbital teratoma with extension into the maxillary sinus, pterygopalatine fossa nasal cavity, and middle cranial fossa is presented.
(5) We found that nerves from the superior cervical and pterygopalatine ganglia form a plexus at the orbital apex corresponding to the retro-orbital plexus found in rabbit, monkey and man.
(6) Cells which project to the middle cerebral artery and were also pBNPir were found in the trigeminal, pterygopalatine and superior cervical ganglia bilaterally but not in the geniculate or otic ganglia.
(7) Removal of the lateral, posterior, and (if necessary) medial walls of the maxillary sinus is followed by resection of most of the contents of the pterygopalatine fossa.
(8) Radiological and computed tomographic studies outlined a mass occupying the left pterygopalatine fossa, which extended into the middle cranial fossa, the maxillary, ethmoid and sphenoid sinuses and the orbit.
(9) Similarly, removal of the ciliary ganglion appeared to increase galanin immunoreactivity, while removal of the pterygopalatine ganglion was less effective.
