The second division is situated in the angleformed by the sphenoid and maxillary bone (just below tlje ear).It sends motory and sensory filaments to the palate, and velumjxilffi. Its filaments penetrate the carotid plexus, receive rein-forcements from the motor centers of the facial nerve and the TiiK «;ki;at sympathetic. 95 Fiy. 60. \ J).

The third division islocated on the submaxillary gland. Its filaments are distributedto the sides of the tongue, the sublingual, and subniaxillaryglands. The otic ganglion is placed below the base of the skulland also connects with the carotid plexus. Its filaments of dis-tribution supply the internal muscles of the maUeus (the largestbone of the tympanum), the membranous linings of the tym-panum and the eustachian tube. Three ganglia, usually desig-nated as the superior, middle, and inferior, connect with thecervical, and spinal nerves. Theii- interlacing filaments are dis-tributed to the muscular walls of the larynx, pharynx, tracheaand esophagus, and also penetrate
