The arrangement of the elastic and collagen fibers in the upper human duodenum was examined. These fibers lie parallel to the muscle fibers in the tunica muscularis. In the submucosa they form a pantographic network arrangement, the cross-over angles of which increase in the oro-aboral direction. The collagen and elastic fibers show a polar orientation among the muscle fibers.
对人体十二指肠上段的弹性纤维和胶原纤维排列进行了检查。这些纤维与肌层中的肌纤维平行排列。在黏膜下层，它们形成一种缩放仪样的网络排列，其交叉角在口侧至肛侧方向上增大。胶原纤维和弹性纤维在肌纤维之间呈极性排列。
