Abstract Alternative
With the aid of transparent specimens (Spalteholz's method) injected with dye and tissue sections, the author investigated the developmental course of medullary vessels in the ilium of 60 human embryos for the periods ranging from the first to the terminal embryonal stages, and obtained the following results. 1) The developmental courses of both the primary bone marrow and the meduallry arteries and veins in the ilium do not differ to any great extent from those observed in the scapula, and the periods as well processes of development are almost the same 2) In the stages later than the fifth embryonal month, no marked changes with the progress of gravid months can be observed in the mode of the distribution of medullary vessels. All the arteries, penetrating more than two at a time, are anastomosed with one another and with many anastomoses of capillaries thus forming networks, they are densely distributed. Veins can now be distinguished into trunks and capillaries. 3) The minimum of two, the maximum of seven, and usually 3-5 nutrition canals can be recognized; and under all circumstances the largest nutrition canal is situated in front of Facies auricularis of the inner side of ilium. In case there are other nutrition canals, they are generally located in a fixed position. All nutrition canals run towards the base of Ala ossio ilium, which is the center of bone marrow, and pass through the bony substance obliquely.
