The Innervation of the Nose.—The innervation of the nasalchambers is derived from the following nerves: 1. The olfactory nerve, the special nerve of the sense ofsmell, is distributed to the olfactory region of the nasalcavities. This nerve communicates with the superior cervicalganglion of the sympathetic, and is therefore influenced bylesions in the upper cervical region. 2. The nasal nerve, a branch of the ophthalmic division ofthe fifth cranial ner\e. distributes filaments to the fore partof the septum and the outer wall of the nasal fossae. Thisnerve is also influenced by lesions of the upper four cervical 124 SPINAL ADJUSTMENT. Fig. 17. Tarts luHueiiced by the iSeveuthCervical Nerve.

The vidian nerve, which supplies the upper and backpart of the septum and the superior spongy bone, communi-cates through the superior cervical ganglion with the upperfour spinal nerves. 4. The naso-palatine nerve, a branch of the superior divi-sion of the fifth cranial nerve, communicates with the superiorcervical ganglion through the connection of the Gasserianganglion with the carotid plexus. 5. The third cervical spinal nerve, by its connection withthe superior cervical ganglion, communicates with the fifthcranial nerve, and thus becomes the most direct source ofinnervation to the nose. 6.
