( 2 ) common integument tissue venous vessel network can be divided into five layers from superficial layer to deep layer : cutaneous papillary layer , hypopapillary layer , hypodermis layer , subdermal layer and deep fascia layer . the artery branch and arteriole that shallowed up from hypopapillar layer get to papillar layer to form vessel network , circuitous and twisted , reflux and anastomose to become postcapillary micro veins and endothelial venule , then anastomose each other and accompanied with artery to enter hypo 小静脉伴行动脉进入皮下组织层、深筋膜层，并与皮下组织层和深筋膜层动脉分支的伴行静脉汇合，分别形成皮下组织层、深筋膜层静脉网，进而汇入轴心动脉的伴行静脉。而真皮下血管网中与动脉不伴行的微静脉汇合成为小静脉，并逐渐聚集增粗，汇合加入浅非伴行静脉属支或即为属支的起点。
Results the posterior antebrachial cutaneous nerve originated from the radial nerve with 2 branches distributed in radial posterior view of the forearm . 7 . 2 nutrient vessels in average were seen to accompany with and supply the nerve , among which the first one was the biggest and accompanied tile nerve farthest and anastomosed abundantly with other nutrient vessels 结果前臂后皮神经起自桡神经，至前臂部主要分为两支，分布于前臂后部桡侧2 / 3 ，其营养血管平均为7 . 2支，其中第一支最粗，并伴行最远，并和其他营养动脉之间存在着丰富的吻合。
The results show that : the glomerulus of the mouse consists of a lobular arteriole within the glomerulus , capillary meshwork lobules and communication branches between the lobules and the efferent arteriolar roots ; there are some sublobular microcirulatary units in lobules ; the glomerulus of chrysolophus pictus is only a tortuous vascular ball ; there are no branches anastomosed between the vascular ; the afferent arteriole is a branch , efferent arteriole is one either , but some efferent arteriole has branches 结果表明：小白鼠肾小球由小球内小叶微动脉、毛细血管网小叶及小叶间交通支和小叶输出血管构成，小叶可分出亚单位；红腹锦鸡肾小球为一簇迂回盘曲的血管团，血管间未见有复杂的分支和吻合；小白鼠和红腹锦鸡入球小动脉和出球小动脉均为一支，但有的出球小动脉有分支。
