A STUDY OF HIPPOCAMPAL MICROANGIOARCHITECTURE WITH THE REPLICA SCANNING ELECTRON MICROSCOPE

Ji Xituan, Zhou Jingde, Fang Taisheng, et al (Department of Anatomy)  
The microangioarchitecture of hippocampus was studied with the replica scanning electron microscope in rats and infants. Typical arteries and their branches were observed in the dorsal and ventral hippocampus of infants. Interarterial, intervenous and arteriovenous anastomoses were seen. Veins and their branches, capillary network and its anastomoses were also observed. A capillary divided into two branches and then they were together with each other like a fried dough twist shape. A vascular unit was observed which consisted of one vein situated centrally and three to four arterioles peripherally. Imprints of precapillary sphincters and postcapillary sphincters wene seen in human hippocampus. Morphology of the hippocampus vessels in rats was not completely similar to men. The diameter of branches which originated from arterioles suddenly changed from the larger to the smaller. There were a lot of impressions of smooth muscles in larger arterioles and their furcations.
