The objective of the study was to determine the morphometric parameters of humerus length during 19-22 weeks of human ontogeny. Conclusions. Ultrasound fetometry of the humerus is one of the basic studies of fetal development. During 19-22 weeks of intrauterine development the right and left humeri grow equally, without significant differences in their length. It has been established that the period of intensive growth of the length of the right and left humeri is from 20 to 21 weeks of gestation.
