ANALYSIS OF THE CONNECTIONS OF THE FIFTH NERVE WITH THE PARS INTERMEDIA (SENSORY PART OF THE FACIAL) Note.—The map shows that the pars intermedia gains access to the ophthalmic nerve through one connection only— viz., the loop of anastomosis between the lachrymal and zygomatic nerves, the fibres being conveyed by the great superficial petrosal to the spheno-palatine ganglion. The first division of the fifth is thus supplied through the second, the current ascending by the spheno-palatine nerves, and taking a reflected course to reach the maxillary nerve and its zygomatic branch. The third, or mandibular division is connected with the pars intermedia through the chorda tympani—first, by a filament from the chorda to the otic ganglion, and secondly, by direct fusion with the lingual. 1 The fibres in Nos. I, 2, and 3 are believed to pass uninterrupted through the ciliary ganglion.
