Thesupramaxillaryganglion, Ganglion supramaxittare (BocJulalekii) , 

 is illustrated in Fig. 472; it is doubtful whether this really is a ganglion. 



The otic ganglion, Ganglion oticum (Arnoldi), lies below the 

 Foramen ovale on the inner surface of the inferior maxillary nerve, con- 

 nected with the nerve by a few filaments ; it is pierced by the internal 

 pterygoid nerve and its branch, which passes to the M. tensor palati 

 mollis. Its branches are : 



a) Nerve to the tensor t y m p a n i, N. ad tensorem tympani ; 



b) Small superficial petrosal nerve, N. pctrosus super- 

 ficialis minor; this nerve runs through a small canal in the great wing 

 of the sphenoid bone, and with the great superficial petrosal nerve to 

 the genu of the N. facialis, where it gives off a twig to the geniculate 

 ganglion, and sends a second down to the tympanic cavity; this latter 

 connects it with the N. Jacobsonii (see Fig. 482) ; 



c) A small branch to the N. ad tensorem veli palatini ; 



d) A small twig to the auricular branch of the auriculo-tem- 

 poral nerve ; 



e) A small branch from the Plexus sympathicus of the middle 

 meningeal artery. 



The sub maxillary or lingual ganglion, Ganglion sub- 

 maxillare s. linguale (see Fig. 474), is placed above the deep portion of 

 the submaxillary gland, near the lingual nerve, with which it is con- 

 nected by several filaments. Its branches supply the submaxillary gland, 

 and accompany the lingual nerve to the mucous membrane of the tongue.
