Diseases of the nervous system .. . Fig. 118.—Transvers Myelitis with Ascending and Descending Staining according to Weigert; ^, triacid stain. The dark areas indicate degeneration. the point of interruption, is important in many respects; first, because indetermining the localization and extent of a disease of the central nervousorgans it is important that we should know what portions of the neuronare implicated, and what deleterious effects the primary focus may have uponremote regions of the neuron system. Very often circumscribed disease ofthe nervous system, particularly in regions where nerve centers or tracts areclosely adjacent (medulla oblongata), causes extensive and serious degenera-tion of entire tracts by damaging many of the neurons situated within theregion of the focus. A knowledge of the course of secondary degeneration is important, too,because not infrequently it enables us to determine tlie seat of the secondaryfocus which would otherwise be very difficult. Finally, these degenerati
