【摘要】 <正> 动物的骨与骨之间由纤维结缔组织、软骨组织或骨组织等相连组成骨连结。将骨骼作为构件分析,两骨关节面直接接触并能产生一定型式相对运动的联结组成运动副,在肌肉收缩的牵引力作用下产生运动。骨连结的原始形式出现在水生的低级脊椎动物中,但其运动幅度较小。而陆栖脊椎动物由于陆地生活环境不同于水中,运动较复杂.在骨与骨间的结缔组织中出现了腔隙,它是在直接连结的基础上分化发展而形成的间接连结。间接连结是骨连结的高级形式,又称动关节。更多还原

【Abstract】 This paper has shown the Moire contour line systems of some joint surfaces of vertebrates, which includes fish of the teleost frog of the amphibian, crocodile of the reptile, black swan of the bird, and orycteropodidae. Lesser panda and golden-haired monkey of the mammal class.Thesis surface contours of vertebrates are not only important in the theoretical research of biomechanics, but very useful for the study of biological evolution and artificial joint as well.更多还原
