Abstract
In Part I, the author reported that the injection replica scanning electron microscope method using methylmethacrylate was a highly effective means for elucidating the microvascular architecture of the bone marrow and presented his findings on the arterial system. A report on the venous system is provided in Part 2. The nutrient vein runs parallel avove the nutrient artery. After it enters the bone marrow, it bifurcates into ascending and descending central veins. The ascending branch curves and bends gently to the proximal end of the femur while the descending branch also bends and curves gently to a point close to the distal end where it divides furthe into 3 to 4 branches. Enroute, numerous sinusoids and collecting sinusoids flow into central vein. Collecting sinusoids of various shapes were observed. The sinusoid is composed of a stereoscopic net-like architecture which extends over the whole bone marrow with the mesh being fine on the superficial zone and rather coarse on the deep zone. No intrasinusoidal capillaries could be observed. All capillaries connected to the sinusoid are considered to the arteries. Thus, with the injection replica scanning electron microscope method using methylmethacrylate, it is also possible to clarify the venous system of the bone marrow.
