摘要
用血管铸型法和大体解剖方法对红腹锦鸡胃动脉的起源和分布情况及胃静脉的回流情况进行了解剖学研究 .结果表明 :红腹锦鸡胃的营养均由腹腔动脉供应 ;腺胃由腺胃背侧动脉和腺胃腹侧动脉营养 ,腺胃背侧动脉直接起自腹腔动脉的左侧 ,腺胃腹侧动脉起自腹腔动脉左支 ;腺胃血液的静脉由腺胃前静脉和腺胃后静脉组成 ,分别汇入左前腔静脉和左肝门静脉回流 ;肌胃由肌胃左动脉、肌胃右动脉和肌胃背动脉营养 ,肌胃左动脉起自腹腔动脉左支 ,肌胃右动脉起自腹腔动脉右支 ,肌胃背动脉从腺胃背侧动脉分支而来 ;回流肌胃血液的静脉有胃右静脉、胃左静脉和胃腹静脉 ,胃右静脉汇入右肝门静脉回流 ,胃左静脉和胃腹静脉汇入左肝门静脉 .另外 ,腺胃和肌胃的表面缺乏主干动脉间的吻合 .
The origination and branches of gastric arteries and the tributaries and return of gastric veins of the Chroysolophus pictus are studied by means of arterial casting and specimen clearing method.The results show that the gastric arteries of the Chroysolophus pictus come from the celiac artery.The glandular ventrilus is supplied by the dorsal and ventral proventricular arteries,the former directly originating from the left side of the coeliac artery,the latter coming from the left branch of the coeliac artery.The veins of the glandular ventriculus are joined by the cranial and caudal proventricular veins which drains into left vena cava vein and left hepatic portal vein respectively.The muscular ventriculus is supplied by the left gastric artery that come from the left branch of the celiac artery,the right gastric artery that come from the right branch of the celiac artery and the dorsal gastric artery that come from the branches of dorsal proventricular artery.There are three main veins on the surface of the muscular ventriculus,which are the right gastric vein that drains into the right hepatic portal vein,the left and ventral gastric veins that drains into the left hepatic portal vein.In additon,it is short of the anastomoses among the arterial trunks on the gastric surface.
