摘要
High intensity neutron beams provide a method of measuring the preferred orientation of apatite crystals in bulk samples of human bone. Measurements at 7 different sites on the scapula show that the c axes of the crystals lie preferentially along the directions of pull of the attached muscles. The highest orientation is found at positions under the influence of only a single group of muscles, e.g. musculus teres major or musculus infraspinatus. In intermediate regions a multiple distribution of crystals is found, able to withstand stresses in more than 1 direction. The technique provides a method of assessing the distribution of stress in bones.
