THE MICROANGIOARCHITECTURE OF HUMAN THALAMUS / 解剖学报

ABSTRACT

The microangioarchitecture of human thalamus was studied by the ink-gelatin injection, thick section transparency, histochemical staining and methacrylate cast under the stereoscope and scanning electron microscopy. There were some impressions of smooth muscular cells on the arteriole, precapillary arteriole, origin of capillary, larger venule, and converging region of each venula. Some circular impressions presented at the course of capillary regularly and discontinuously, which might be caused by contraction of pericytes of capillary. The microvascular anastomoses were rich and complex. Besides capillary anastomoses of different shape, there were many anastomoses occurred between two arterioles, or between several arterioles. The form of venular anastomoses was similar to arterioles. The anastomosis between arteriole and venule was observed occasionally. The relationship of characteristic of vertical branches of arterioles to thalamic hemorrhage was discussed.
