| Abstract: | The characteristics of the skeletons of the trunk in bactrian camel are the following. The dorsal and ventral cristals of the atlas are not obvious. There are the alar foramen (For, alare), the lateral vertebral foramen (For. vertebrale laterale) and the transverse foramen (For. transversarium) in the atlas. The cranial branches of the transverse process of the cervical vertebrae 3～5 are longer than the caudal branches. There is not very distinct intermediate branches of the transverse process on the cervical vertebra 6. The cervical vertebra 7 is not branched. There are 12 thoracic vertebrae (Vertebrae thoracicae), of which the dorsal spinal process (Proc. spinosus dorsalis) in T3～6 are the highest. The 12 pairs of the ribs (costae) are wide and rough. The lumbar vertebrae (Vertebrae lumbales) are 7 badges. The sacrum (Os sacrum) is formed by the fusion of 5 sacral vertebrae, of which the promontorium is fairly prominent. There are about 20 caudal vertebrae (vertebrae caudalis). The sternum is made up of 7 sternebrae, its ventral surface is somewhat smooth. The thorax is like the form of apex-cut-buttlet, its cranial thoracic aperture (apertura thoracic cranialis) is like a inverted isosceles triangle, its caudal thoracic aperture (apertura thoracis caudalis) is very wide and long. |
