猴甲状腺微血管构筑的扫描电镜观察

本文在扫描电镜下观察了猴甲状腺微血管的构筑。甲状腺的血管自小叶间动脉、滤泡间小动脉、滤泡间微动脉,最后由入球微动脉在滤泡周围分支形成篮网状滤泡毛细血管网。该网自动脉极向静脉极过渡形成三级毛细血管,即由入球微动脉首先分出分支毛细血管网,延续为网状毛细血管网和集合毛细血管网,最后在滤泡的静脉极汇集成出球微静脉。猴甲状腺滤泡毛细血管网大小不同,且独立存在。

OBSERVATIONS ON THE MICROVASCULAR ARCHITECTURES OF THE THYROID IN THE RHESUS MONKEY UNDER THE SCANNING ELECTRON MICROSCOPE

The origin of the thyroid vessels is as follows: the interlobular arteries gradually branch into the interfollicular small arteries, interfollicular arterioles and afferent glomerular arterioles in turn. The latter at the arterial pole of the follicles ramify into the basket-like capillary networks around the each follicle. From the arterial pole to the venous pole these networks were found in three grades networks. Namely: branched capillary networks, reticular capillary networks and assembly capillary networks. Finally, all these assembly capillary networks converge to become the efferent glomerular venules. The capillary networks of the thyroid follicles in the Rhesus monkey differ from one another in size. However, all of them exist independently.
