双峰驼髂内动脉的形态学观察

MORPHOLOGICAL OBSERVATION ON INTERNAL ILIAC ARTERY IN TWO-HUMPED CAMEL

采用血管内灌注有色油画颜料的方法,解剖观察了双峰驼髂内动脉的分支及分布情况.髂内动脉是骨盆部动脉的主干,其分支有脐动脉、臀前动脉、闭孔动脉、臀后动脉和阴部内动脉.阴部内动脉的分支有阴道动脉、直肠中动脉、会阴腹侧动脉和阴蒂动脉.在双峰驼未见有会阴背侧动脉.还就双峰驼和其它家畜髂内动脉的解剖学特点进行了比较讨论.

The branches and the distribution of the internal iliac arteries of the two-humped camels were observed and studied by means of the introarterial injecting oildry. The internal iliac artery is the main arterial trunk of the pelvic and its branches are the umbilical,cranial gluleal,obturator,caudal gluteal and internal pudendal arteries. The internal pudendal artery gives off the vaginal,middle rectal,ventral perineal arteries and the clitoral artery. The dorsal perineal artery was not found in two-humped camel. The anatomical characteristics of the internal iliac artery of the two-humped camel have been discussed and compared with those reported other domestic species.
