title: [Qualitative and quantitative parameters of the growth of the skeleton of the extremities of embryos and early fetuses in man].
abstract: One hundred and ten human embryos 6-9 weeks of the intrauterine development have been investigated. Sequence of anatomical differentiation of the skeleton in the composition of the upper and lower extremities has been stated. Quantitative changes of the parameters of each anlage at successive stages of the development are analyzed. Equations of regression are obtained, owing to them it is possible to determine age of human embryos and early fetuses in dependence on size of separate fragments of the extremities.
