Not illustrated. 1873 edition. Excerpt: ... to or excite mental acts, there is abundant proof that the cerebro-spinal filaments passing through the ganglia are constantly operating, although insensibly, in subjection to the cerebro-spinal centres. The ganglia, however, not only diffuse the influence of impressions coming from and sent to the cerebral and spinal centres, but they are nervous centres themselves, and especially centres of numerous reflex acts in non-voluntary muscles. Excite-secretory and excz'tonutrz'ent;0r0pertz'es.--In addition to this excito-motory function of the sympathetic system, there is another of great importance, denominated by Dr Campbell, of the United States, excite-secretory. We have previously seen, however, that secretion in glands is only a form of nutrition; and the influence of this system would appear not only to be exerted on glands, but on blood vessels and nutrition generally. It is, therefore, also excite-nutrient, and carried on wholly independent of the cerebro-spinal system. Thus it has been shewn by Sir B. Brodie that division of the crural and sciatic nerves neither retarded nor impaired wounds and fractures of the inferior extremities; while numerous experiments have proved that injury to the large sympathetic ganglia occasion the most destructive effects to the nutrition of the parts which receive nerves from them. The experiments of Brown Sequard and Harley on the supra-renal capsules, have shewn that it is diflicult to preserve animals if the semilunar or solar ganglion be much injured in the operation; but if this be avoided, animals can live without the supra-renal capsules for a length of time. Again, as illustrative of the general influence of the sympathetic system over nutrition, is the fact that certain foetuses have...
