哺乳动物的肝静脉系

The System of the Hepatic Veins of Mammals

在分叶明显的肝脏,每叶均有肝静脉汇集其静脉血。左内侧叶和右内侧叶之间发生愈合的肝脏,其间出现肝中静脉。马属动物方叶与右叶之间有较深裂隙,肝中静脉缺如。愈叶程度高的肝脏(牛、羊),主要肝静脉仅为左、中、右三支,故肝静脉的数量与愈合相关。国际兽医解剖学名词(NominaAnatomicaVeterinaria,N.A.V.)的相关条目是不合适的,应予补充。

In the obvious lobated livers,there are always the hepatic veins which draw the venous blood from each lobe.In the livers in which the medial parts of the left medial lobe and the right medial lobe are fused,there is the v.hepatica media between the two lobes.In equine there is no v.hepatica media because a deep fissure is located between the quadrate lobe and the right lobe.In the wellfused livers(cattle,goat),there are only the v.hepatica sinistra,the v.hepatica media and the v.hepatica dextra.So the number of the hepatic veins is related to the fusion of the hepatic lobe.The related list about the hepatic veins in the Nomina Anatomica Veterinaria(N.A.V.)is not right and should be replenished.
