The cineritious ismore vascular, and composed ofkidney-shaped globules, contain-ing a vesicular nucleus with anucleolus. These globules aresoft, and of a yellow or brownishcolor. The ganglions and nervouscentres consist of a mixture ofwhite fibres and gray sheath of the nerves is call-ed neurilemma, and the enclosedmatter neurine. The trunks of nerves frequently interchange trunksor fasciculi, forming anastomoses; and a combination of these anasto-moses into a netwoik forms a plexus. Numerous small elliptical bodies, attached to the ulnar and digitalnerves, are called Pacinian corpuscles; these have no terminal loops,being the only exception to the general rule. Microscopic observation makes out the elements of the nervous sys-tem to be, white nerve-fibres, gray nerve-fibres, nerve-cells, and NERVOUS SYSTEM. NEUROLOGY. 163 Fig. 85 represents the microscopic elements of thenervous structure. 1. Mode of termination of whitenerve-tibres in loops ; three of these loops are simple,the fourth is convoluted. The latter is found in situ-ations where a high degTee of sensation exists. 2. Awhite nerve-ribre from the brain, showing the vari-cose or knotty appearance produced by traction orpressure. 3. A white nerve-fibre enlarged to showits structure, a tubular envelope and a contained sub-stance—neurilemma and neurine. 4. A nerve-cell,showing its composition of a granular-looking cap-sule and granular contents. 5. Its nucleus containinga nucleolus. 6. A nerve-cell, from which severalprocesses are given off; it contains also a nucleatednucleus. 7. Nerve-granules. Fig. 85.
