[Blood vessels of the epiphysis in comparative-anatomical aspect].
The structure of the epiphysis and its inner blood vessels were studied in the representatives of nine orders of placental mammals and in man by means of injection of stained masses into the arteries and veins and subsequent preparation of histological sections. Not only form and topography of the organ differ in the representatives of different orders, but histological picture of the epiphysis is specific for each of them. In insectivores and chiroptera the loops of the inner three-dimensional capillary network are stretched along the longitudinal axis of the organ. In the epiphysis of carnivores, ungulata and monkey, the intraorganic vessels are situated in stromal trabeculae and the loops of the capillary network have polygonal shape. The intraepiphyseal vessels in man are arranged in peculiar baskets which envelope parenchymal lobules. The intraorganic veins beginning from the loops of the capillary network do not follow the arteries penetrating into the organ, but independently go to different surface parts of the organ where they flow into extraorganic veins.
