The physiological necessity of the dual afferent blood supply of the liver and the morphological features of the macrocirculation are well understood. The microcirculation, however, still poses a number of unsolved questions. In particular the nature of the terminal junctions of the arterial and portal blood stream with the sinusoids has so far not been satisfactorily elucidated (1-2). Scanning electron microscopy alone or in combination with corrosion casts cannot solve the problem, because it remains difficult to tell the different vessels apart. Under favorable circumstances the terminal portal vein is the easiest to be distinguished with corrosion casts. This is due to the fact that its relatively wide branches surround the classical liver lobules along the major parts of their circumference. The diameter of the terminal hepatic artery is in its initial segments not as wide as the initial segments of the terminal portal vein.

Using standard techniques of scanning electron microscopy (SEM), over 1000 human hair defects have been studied. In several of the defects, the pathogenesis of the abnormality has been clarified using these techniques. It is the purpose of this paper to present several distinct morphologic abnormalities of hair and to discuss their pathogenesis as elucidated through techniques of scanning electron microscopy.
