本文用2侧成人新鲜尸体上肢,经肱动脉灌注ABS丁酮溶液,制成铸型样品,喷镀金膜。在扫描电镜下,观察了手鱼际和小鱼际皮肤及浅、深筋膜微细血管的立体构筑。微血管网可分为5层:(1)乳头层网:可见排列整齐的皮纹血管及乳头毛细血管;(2)乳头下层网:血管网眼大、小不均,呈多角形;(3)真皮深层血管网:在纵横交错的微血管网中,有散在或聚集成团的毛细血管球;(4)浅筋膜层网:在粗大的血管干周围,形成小叶状血管网;(5)深筋膜层网;可见并行排列的干线血管。左右侧之间、鱼际和小鱼际之间,微血管网的形态无明显差民。
In this study, 2 adult fresh cadaveric upper limbs were infused with ABS butanone solution through the brachial artery to make a cast sample and spray gold film. Under the scanning electron microscope, we observed the three-dimensional structure of the skin of the hand and the small intertidal skin and the superficial and deep fascia. Microvascular network can be divided into five layers: (1) nipple layer network: visible arrangement of dermal capillaries and nipple capillaries; (2) the lower nipple network: vascular network large and small uneven polygons; (3) leather Deep vascular network: in the criss-cross microvascular network, scattered or clustered into a group of capillaries; (4) superficial fascia layer network: in the thick of the vascular stem around the formation of lobular vascular network; (5) deep tendons Film network; visible parallel arrangement of the main line of blood vessels. Between the left and right, between the fishbone and small intertidal, microvascular network morphology no significant difference.
