七彩山鸡胃动脉和静脉的解剖学观察

用血管铸型法和大体解剖学方法对6只七彩山鸡（Phasianus colchicuses)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观察。结果发现：七彩山鸡的胃动脉均由腹腔动脉分出，腺胃由分自腹腔动脉根部的腺胃背侧动脉和由腹腔动脉左支分出的腺胃腹侧动脉营养；肌胃由肌胃左动脉（是腹腔动脉左支的延续）、肌胃右动脉（是腹腔动脉右支的终支之一）和肌胃背侧动脉（是腺胃背侧动脉向后分布于肌胃背侧缘的分支）营养。腺胃的静脉由腺胃前静脉和腺胃后静脉组成，分别经左前腔静脉和左肝门静脉回流。肌胃的静脉有胃右静脉、胃左静脉和胃腹静脉。胃右静脉经右肝门静脉回流，胃左静脉和胃腹静脉经左肝门静脉回流。另外腺胃和肌胃的表面缺乏主干动脉间的吻合。

A study of the arteries and veins gastrica of the Phasianus colchicuses

The origination and distribution of arteries gastrica and the distribution of veins gastrica of six Phasianus colchicus were studied by means of arterial casting and specimen clearing method.The results showed that the arteries garstrica of the phasianus colchicus come from the artery celiaca.The glandular ventriculus is supplied by the artery proventricularis dorsalis and ventralis,the former directly originating from the left side of the artery celiaca,the latter coming from the ramus sinister artery celiacae.The veins of the glandicular ventriculus are joined by the veins proventricularis cranialis and caudalis,which drains into the vena cava sinistra cranialis and vein portalis hepatica sinistra respectively.The muscular ventriculus is supplied by the artery gastrica sinistra that come from the ramus sinister artery celiacae,the artery gastrica dextra that come from the ramus dexter artery celiacae,the artery gastrica dorsalis that come from the artery proventricularis dorsalis or directly come from the artery celiaca.There are three main veins on the surface of the muscular ventriculus,which are,the vein gastrica dextra that drains into the vein portalis hepatica sinistra,the vein gastrica sinistra and ventralis that drains into the vein portalis hepatica sinistra.In addition,it is short of the anastomoses among the arterial trunks on the gastric surface.
