石鸡胃的血液供应

A study of gastric blood supply on Alectoris graeca

用ABS血管铸型法对5只石鸡胃动脉的起源与分布及胃静脉的分布与回流情况进行了解剖观察.结果表明:石鸡胃的动脉均由腹腔动脉的分支供应.腺胃由腺胃腹侧动脉和腺胃背侧动脉供应营养;肌胃由胃左动脉、胃右动脉和胃背侧动脉供应营养.回流腺胃的静脉包括腺胃前静脉和腺胃后静脉,腺胃前静脉收集腺胃前部大部分胃壁的静脉血经后腔静脉回流;腺胃后静脉收集腺胃后部及胃凹的静脉血经左肝门静脉回流.回流肌胃的静脉包括胃左静脉和胃右静脉,分别收集胃左侧面和胃右侧面的静脉血,经左肝门静脉和右肝门静脉回流.

The origination and distribution of gastric arteries and the distribution and drainage of gastric veins on five Alectoris graeca were studyed by means of ABS blood vessels casting method.The results showed that the gastric arteries of Alectoris graeca originated from the celiac artery.The proventriculus was supplied by both dorsal and ventral arteries of proventriculus.The ventriculus(gizzard)was supplied by the left,right and dorsal gastric arteries of ventriculus.The veins of the proventriculus included both cranial and caudal veins of proventriculus,the former which drained into the vein of postcava collected mainly vein blood on the mostpart cranial wall of proventriculus,the latter drained into the left hepatic vein mainly accumulated vein on the caudal wall and Isthmus gastris.The veins on the ventriculus included the left gastric vein and the right gastric vein which drained into the left and right hepatic veins respectively.
