stance is arranged in the form of striae which run in the 722 BARKER: ANATOMY AND PHYSIOLOGY OF NERVOUS SYSTEM. [X. Y. Med.

These striae, as a rule, are not continuous fibrils, but the striated arrangement is dependent in the main \\ Fig. 51. — Nerve cell from ganglion on dorsal root of a cervical nen-e of a rabbit. (After Nissl.) Stichochrome nerve cell in apvknomorphous condition. Two large nucleoli are shown within the nucleus. The asone at the upper end of the cell is seen to contain none of the etainable substance of Nissl. upon different stained elements, threads, spindles, and granules, more or less isolated and in rows. These vari- I ]'l! %'\ ous elements, without being directly continuous, arrange themselves in rows running in the same direction within the cell order hoodia body. Occasionally, in this group of nerve cells, there occur examples in which here and there a thread or a row of granules assumes a direction opposite to that of cheap hoodia the general striation, an appearance, however, which would not prevent the cell from being included in this cate- :: • gory. So far, Nissl has distin- guished four types of stichochrome cells, represented hoodia p 57 by the nerve cells of motor nuclei (Fig. 49), the large cells of Ammon's horn (Fig. 53), certain cells of the cere- bral cortex, and spinal ganglion cells (Fig. 51). The third group of somato- chrome nerve cells includes those of the so-called arkyostichochrome type, in which the striated is united with a networklike struc- tural character in the most inti- buy hoodia online mate manner, so that one can not decide which mode of arrangement of the stainable substance is most characteristic of the cell. Nissl cites as a typical example of cells of this sort the Purkinje cells of the cerebellar purchase hoodia online cortex (Fig. 54). Lastly, as a fourth group of somatochrome nerve cells, Nissl describes the gryochrome (ypv) type, in which the stainable con- stituent of the cell body is entirely made up of small granules. The granules are not distributed, how- ever, at random in the cell body, hoodia 57 but tend to form threads or heaps, so that a distinct habitus can be at- tained. Nissl does not give pictures of cells of this type, but mentions that they are particularly, though not ex- clusively, found in the corpus striatum.
