Vergleich der histologischen Struktur der Kompakta der langen Röhren-knochen bei Maus, Hamster, Ratte, Meerschweinchen, Kaninchen, Katze und Hund während der Altersentwicklung

This paper reports on histological examinations of the diaphyseal structure of the long bones (humerus, radius, ulna, os femoris and tibia) of mouse, hamster, rat, guinea pig, rabbit, cat, and dog using six animals in three different age groups. There are considerable differences in structure between the species. The results show that with increasing height in the evolution of the species and period of life, as well as advancing age, the differentiation and complexity of bone structures increases. The differences in structure between the localization of bones within the individual species are not considerable. The species comparison results in great similarities between the bone structures of each of mouse and hamster, of rat and guinea pig, as well as of cat and dog. The bone structure of the animals examined becomes more similar to the human structure from mouse, hamster, rat, guinea pig, rabbit, and cat to dog.
