环颈雉胃的血供

用血管铸型法和大体解剖学方法对环颈雉胃动脉的起源、分布及胃静脉的回流情况进行了解剖学研究。结果表明，环颈雉的胃动脉均由腹腔动脉分出；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态的左侧，腺胃腹侧动脉起自腹腔动脉左支。腺胃血液的静脉有腺胃前静脉和腺胃后静脉，分别汇入后腔静脉和左肝门静脉。肌胃由肌胃左动脉、肌胃右动脉和肌胃背侧动脉营养，肌胃左动脉起自腹腔动脉的左支；肌胃右动脉起自腹腔动脉的右支；肌胃背侧动脉从腺胃背动脉分支而来。回流肌胃血液的静脉有胃右静脉、胃左静脉和胃腹侧静脉；胃右静脉汇入右肝门静脉，胃左静脉和胃腹侧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。

A Study of the Gastric Blood Vessels of the Ring-necked Pheasant

The blood supply for stomaches of five Ring\|necked Pheasants were studied by means of arterial casting and specimen clearing methods. The results showed that the garstric arteries of Ring\|necked Pheasants came from the coeliac artery. The glandularis ventrilis was supplied by the dorsal and ventral proventricular arteries, the former directly originating from left side of the coeliac artery, the latter coming from left branch of the coeliac artery.The veins of the glandicularis ventriculi were joined by the cranial and caudal proventricular veins, which drained into vena cava posteriov and hepatic portal sinister respectively.The muscularis ventriculus was supplied by the left gastric artery that came from left branch of the coeliac artery, the right gastric artery that came from right branch of the coeliac artery and the dorsal gastric artery that came from the branches of proventricular artery.There were three main veins on the surface of muscularis ventriculus, which were the vein that drained into the right hepatic portal vein,the left and ventral gastric veins that drained into the left hepatic portal vein.In addition,it was short of the anastomoses among the arterial trunks on the gastric surface.
