@article{oai:niigata-u.repo.nii.ac.jp:00021471, author = {山田, 格}, issue = {4}, journal = {新潟医学会雑誌, 新潟医学会雑誌}, month = {Apr}, note = {Two fold purposes of this article are: to present a new interpretation on the configulation of the mammalian flexor digitorum superficialis muscle, on the one hand, and its implication to the phylogenetical status of Tarsius, on the other. Quite contradictorily to the general belief, the mammalian flexor digitorum superficialis is composed of two distinct muscle portions. It was first revealed in human adult anatomy (Yamada, 1986), and confirmed in several species of primates and insectivora examined by the present author (Yamada, 1986; 1987; 1989). In all the prosimian species observed in the present study (8 species), the muscle in question is affirmed to be composed of two independent muscle sections, however, how these two different muscle sections fuse in lemuriformes differs from that of lorisiformes. The composition of the muscle, in phylogenetically controversial Tarsius, is proven to be the lorisoid type. This result gives a strong support for tarsiers to be included in prosimii whereas there are opinions insisting its anthropoid affinity. Gross anatomy has been criticized as too descriptive, or even not scientific. These criticisms are for those anatomists just seeking anomalies or taking to statistical analyses. We have to push strongly forward the analytical gross anatomy which can be brought forth when utilizing onto and phylogenetical assessments.}, pages = {240--245}, title = {浅指屈筋の構造に基づくメガネザルの系統学的位置の検討}, volume = {105}, year = {1991} }
