[Development of the papillary designs of human fingers].
In 22 human embryos and fetuses from 6 to 36 weeks of age successive formation of papillary patterns in the distal phalanges of the fingers have been studied. It has been stated that the papillary pattern begins forming with definition of its typical model, that is the central fragment of the pattern appears the first; the delta formation completes the process. The central fragment of the pattern is distinctly seen in the 16-17-week-old, and the delta-in the 22-24-week-old fetuses.
