Abstract:
The SEM specimens of the blood vessels of the gall-bladder in the full term fetus were produced with the methyl methacrylate cast. The specimens were dryed and gilded with EIKO. IB-3. and then observed under scanning electron microscope. The microvessels of the wall of gall-bladder obviously were divided into three layers, namely: serous vessels, muscular vessels and mucous vessels. The serous and muscular vessels are similar to that of the intestinal canal. However the mucous vessels were characterized by subepithelial capillary networks and veins of large calibre in the lamina propria. The capillary networks were connected directly with the venous plexus by the capillaries. There are fewer arterioles passing and branching among the venous plexuses. Each arteriole was connected to capillary networks. The short capillary was seen frequently between the arterioles and the venous plexus, serving as communication between them.
