通过对双峰驼20个关节(左、右肩关节、肘关节各5个)的解剖,发现如下一些特征:肩胛骨关节盂切迹不明显.肱骨远端内侧髁关节面无滑液窝;髁间沟由后向前内侧斜行,其与关状面之间的夹角约为10度。肘关节囊前壁有前斜韧带加强。肘外侧侧副韧带比肘内侧侧副韧带强厚得多,且后者远端没有2个止端.桡尺骨间的产节已基本骨化.
Through the anatomy of 20 articulations (left and right shoulder joints and 5 elbow joints) in Bactrian camels, the following features were found: the glenoid notch in the scapula was not obvious, and the synovial fossa of the medial condyle in the distal humerus had no synovial fossa. Between the ditch from the back to the inside oblique line, the angle between the closure surface and about 10 degrees. Elbow capsule anterior oblique wall with anterior reinforcement. The lateral collateral ligament of the elbow is much thicker than the medial collateral ligament of the elbow, and the distal end of the elbow has no 2 ends. The section of the radioulnar joint has been ossified.
