The aim: To study the forms of anatomical variability of the external structure of the upper and lower parathyroid glands in the fetal period of human ontogenesis. Materials and methods: The study involved 48 specimens of human fetuses with 81,0-375,0 mm of crown-rump length (CRL). The study was conducted by means of macromicroscopic preparation, morphometry and variation statistics method. Results: The age and individual anatomical variability, complex way of development and formation of synotopic embryotropographic correlations of the upper and lower parathyroid glands in the prenatal period of human ontogenesis create numerous prerequisites for the emergence of variants of their external structure and topography in the fetuses of both different and the same age groups. Conclusions: There is a significant anatomical variability of the upper and lower parathyroid glands in 4-10-month-old fetuses, which is manifested by varieties of their shape and topical location. Aplasia of the upper parathyroid glands, which was found in two human fetuses aged 7 months, was due to the fetures of their organogenesis and the formation of syntopy in the embryonic and prefetal periods of their development. Parathyroid glands are mainly supplied with blood by the branches of the inferior thyroid artery. The branches of the upper thyroid artery and the arteries of adjacent organs: larynx, trachea and esophagus are involved in the blood supply. The right and left inferior thyroid veins are tributaries of the corresponding brachiocephalic vein, paired (right and left) superior and middle thyroid veins are those for the internal jugular vein.

The occurrence of various devices that are interlinked to provide advanced connectivity throughout the systems revolves around the formation of 5G systems. Artificial Intelligence plays a fundamental role in the 5G networks. The popularity and integration of 5G have emerged through advanced cellular networks and many other technologies. This innovative and speedy network has built strong connections in recent years, its conduct in business, personal work, or daily life. Artificial Intelligence and edge computing devices have optimized internet usages in everyday life. The growth of 5G networks is effective in the AI/ML algorithms due to its low latency and high bandwidth, which also performs real-time analysis, reasoning, and optimization. The 5G era has fundamental features that are highlighted among the revolutionary techniques which are most commonly used by cellular device networks, such as the resource management of radio, mobility management, and service management, and so on. This work also integrates the selection of spectrum and access the spectrum which AI-based interface to accomplish demands of 5G. The strategies which are introduced are Fractional Knapsack Greedy-based strategy and Language Hyperplane approach which becomes the basis of subsequently utilized by strategies of Artificial Intelligence for purpose of the selection of spectrum and the right allocation of spectrum for IoT-enabled sensor networks.

To obtain data about the formation of fetal macroscopic structure and topography of the thoracic part of the aorta, which can be used for age-related mapping, it is necessary to determine a standard sequence of steps during the preparation of these structures. The purpose of the study was to determine the method of the best rational sequence of actions during the preparation of areas of the posterior mediastinum in human fetuses to obtain standard results, useful for comparing in the age aspect. Materials and methods. The study was performed on 35 human fetuses of 4-10 months by macromicroscopic preparation of organs, vessels, and nerves of the posterior mediastinum. Results and discussion. In the study of fetal anatomical variability of branches and nerves of the thoracic aorta in the age aspect, the algorithm of anatomical preparation of the posterior mediastinum becomes a priority. However, in the literary sources available to us, we did not find information about the sequence of actions during the preparation of the posterior mediastinum, including the thoracic aorta in human fetuses. The innervation of the thoracic part of aorta on both sides mainly involves the branches of the II-VI thoracic nodes of the sympathetic trunk, the great visceral nerve, and the branch of the vagus nerve. Adherence to the following sequence of actions during the preparation of the posterior mediastinum, and in particular, the branches and nerves of the thoracic aorta, in human fetuses, provides not only the scientific value of the results but also the rational use of biological material. Conclusion. The proposed and tested method of dissection of nerves, visceral and parietal branches of the thoracic aorta in human fetuses provides a standard for obtaining data about their typical, individual, and age anatomical variability. The innervation of the thoracic aorta mainly involves the branches of the II-VI thoracic nodes of the sympathetic trunk, the great visceral nerve, and the branch of the vagus nerve. Nerve branches leading to the thoracic aorta from various sources enter its wall either together with blood vessels or in isolation. In human fetuses, between the right and left sympathetic trunks and the thoracic part of the aorta, in addition to the intermediate plexus or collateral trunk, a paraaortic plexus is found, the branches of which participate in the innervation of the thoracic aorta. Bilateral asymmetry of the structure and topography of the plexuses of the thoracic aorta was detected. The sequence of actions used during the preparation of the thoracic aorta in human fetuses preserves the natural appearance and relationships between the branches and nerves of the object of the study
