| 摘 要： | 解剖双峰驼后足远趾节间关节１６个，并与其他家畜的对等器官相比较，双峰驼的后足远趾节间关节在形态结构方面有以下显著特征：①无远籽骨和蹄软骨，因而亦无相应的远籽骨韧带和蹄软骨韧带；②有两条背侧韧带，与在犬、猫等趾行动物体上所见相同；③趾间远韧带呈宽板状，交叉纤维甚少，大部分纤维平行排列；④轴侧侧副韧带起于中趾节骨远端韧带窝，止于远趾节骨蹄骨角附近，这与马的相同而与牛的不同。

| Abstract: | The sixteen distal interphalangeal joints of the hind feet ( Articulationes interphalangeae distales pedis ) in bactrian camels were dissected and compared with the reciprocal ones in the other domestic animals. The results showed that there were notable characteristics in shape and structure of the distal interphalangeal joint of hind foot in bactrian camel. 1. There was no the distal sesamoid bone ( Os sesamoideum distale ) in the joint. Therefore there were neither correlative distal sesamoid ligaments nor ligaments ungulic cartilage 2. There were two dorsal ligaments in the joint, which were identical with that in Digitigrade, such as ones in a dog and a cat. 3. There were a few crossfibers, however, the most of fibers were paralleled in arrangement ways. 4. The axial collateral ligament originated from the distal ligament fosse of the middle phalangealbone ( Os coronale ) and ended at axial process of the distal phalanx ( Ungulate ). This was the same case as that in horse, but was not alike that in cattle. The structures of the distal interphalangeal articulations of hind foot in bacteria camel appeared comparative large different from that of Unguligrade in some degrees, but they were similar to that of Digitigrade. It might be related to the ways for the ends of hind feet in bacteria camel to touch the ground when walking and standing. |
