ANATOMICAL FEATURES OF THE PETROUS PART OF THE TEMPORAL BONE IN HUMAN FETUSES 16-22 WEEKS OF DEVELOPMENT
Abstract
The objective of the study is to identify the main anatomical features and obtain new data on the descriptive and quantitative anatomy of the petrous part of the temporal bone of the fetus from 16 to 22 weeks of development.
Material and methods. The study material was 60 fetuses of both sexes, without malformations, at the gestation period of 16-22 weeks, taken from the collection of the Department of Human Anatomy of the OrSMU. А set of standard morphological techniques was used: macromicroscopic preparation, morphometry, photographing, histotopographic method and statistical processing of the obtained results.
Results. It was revealed that throughout the studied period of ontogenesis, the petrous part of the temporal bone is fully formed, densely covered with the dura mater and does not differ in any way from the pyramid of an adult person. The results of measuring the length of the pyramid show that its average value increases from 16 to 22 weeks of prenatal ontogenesis. In addition, in this period, some fetal features of its anatomy are revealed in the petrous part of the temporal bone.
Conclusion. The results obtained during the study, expand and supplement the available information on the anatomy and topography of the petrous part of the temporal bone, and may be useful for a deeper understanding of the formation and development of the presented area.
