When, however, a vertebra is sofar out of alignment that the equalizing of muscular andligamentous laxity and rigidity on both sides will not permitit to spontaneously resume its proper position, then mechanicalmeans are required. Sleep is the great restorative of vital energy because itproduces a state wherein the generation of nerve-impulses istemporarily diminished or suspended. It is because the con-tinuous flow of impulses ceases during this time, that thestate of constant contraction of the muscles is absent, andrelaxation of muscles and ligaments takes place. In like man-ner, most organs, during deep sleep, cease to function be-cause the nerve impulses necessary to their functional activityare not being generated. Were the nerve impulses still flow-ing along the nerves as during our waking hours, there wouldbe no relaxation during sleep, and the organs would neverrest. Fatigue, which is present at the end of the day, is simply, 176 SPINAL ADJUSTMENT. Fig. 39. PosTEUioR Aspect of Spine. (A) Lateral displacement of the second dorsal vertebra to the left.
