Synopsis:

Due to their pronounced intraspecific variability and to difficulties in defining their evolutionary trends in mammalian phylogenies, peripheral blood vessels have been neglected in comparative studies. Supported by the Sonderforschungsbereich 89 (Car- diology) of the Deutsche Forschungsgemeinschaft, we have reconstructed the ontoge- of the blood vessels of the tree shrew, Tupaia belangeri, on the netic morphogenesis basis of a series of developmental stages. The arteries of the lower extremity are described and discussed here. Besides describing the morphogenesis of the arteries in Tupaia, it is the aim of this study to explain the variability of the arteries of the pelvic extremity among mammals, and especially among primates including man, on the basis of a common developmen- tal pattern. This can be shown in the following example. In the popliteal region of most adult mammals the arteria poplitea profunda is situated under the musculus popliteus. In the adult Tupaia, as well as in primates, this artery is missing but, superficial to the musculus popliteus, an arteria poplitea super- ficialis exists. It seems difficult to explain such a case of "discontinuous evolution," because it is hard to imagine the position of the artery should have shifted through the muscle. The present investigation and the literature show that early in the embryonic development of a primate, man, and of Tupaia, both the arteria poplitea profunda and the arteria poplitea superficialis are present.

Product Description: Some abnormalities of the arterial system of adult individuals can be interpreted as retentions of a state that normally occurs only during early embryology. The teratogen thalidomide primarily affects the anlagen of the blood vessels and only secondarily the development of the complete limb. To understand the normal development of limbs as well as limb malformations the morphogenesis of their blood vessels must be considered. Describing the embryonic development of the arteries of a primitive mammal, this text focuses on the tree-shrew Tupaia belangeri to explain the variability among other mammals on the basis of a common developmental pattern. It establishes criteria for the comparison of data published in the literature.
