摘　　要：为了进一步观察鼠颞颌关节各部位的有胶原纤维和弹力纤维，作者应用计算机图象分析系统和电镜来研究鼠颞颌关节中三种弹力纤维的分布与形态。结果表明：在关节各部位中的弹力纤维以微原纤维和前弹力纤维为主。关节盘表面的微原纤维排列方向与胶原纤维几乎成直角。在关节盘表层下方和关节其它部位的弹力纤维排列上未见方向性。弹力纤维在关节盘和关节囊中形成一个广泛的纤维网。We study the Elastic System Fibers(ESFs) in the rat mandibular joint using light microscope and image analyzer system and Electron Microscope The results showed that the ESFs in the articular disc and capsule were more than in the articular cartilage In addition,microfibrils and elaunin were the principal ESFs in all the articular components The microfibrils in the articular surfaces ran at nearly right angle to the collagen fibers The ESFs beneath the articular surfaces and the other articular components showed no specific directivity ESFs construct an extensive fibers network in the disc and the capsule
