Abstract: Abstract
Background: The considerable progress in recent decades in the fields of imaging and vascular surgery and
increasing demand for diagnosis and surgical procedures, requires a constant review of the data on morphological
variants of the upper limb arteries. The aim of our research was to study the individual variability of the axillary
region arteries, according to gender, age and side of the body.
Material and methods: This is a retrospective and descriptive study. The variability of arterial architectonics
of the axillary region arteries was studied on 210 upper limb angiographies. The analysis of the angiographies of
the upper limb arteries was done with the aim to transfer the anatomy of the axillary region arteries from the virtual model to the real one, in order to identify their variability according to gender and side of the body, based on
the following criteria: origin, course, numerical variations, branching, etc.
Results: The variability of the axillary region arteries was established in 62 patients (29,52%), among which
36 (17,14%) were males, and 26 (12,38%) – females. Variants of origin of the axillary region arteries were revealed in 4,76%, numerical variants were identified in 9,53%, and presence of the common trunks – in 21,43%. The
common trunks were variable on both criteria formation and branching.
Conclusions: The most variable branch of the axillary artery was the posterior circumflex humeral artery,
followed by variations of the lateral thoracic and subscapular arteries.

Abstract: Abstract
Background: Finding out the features of morphogenesis and topographic changes of suprahyoid region (SHR)
of the neck and its structures in the dynamics of human intrauterine development (IUD) remains a relevant area
of morphological research.
Material and methods: Thirty preparations of human prefetuses of 14.0-80.0 mm parietococcygeal length
(PCL) (7-12 weeks of IUD) were studied using a complex of modern methods of morphological research.
Results: On the basis of obtained digital indicators of the main morphometric parameters of human SHR in
the dynamics of the prenatal period of IUD the critical periods of development of the region were clarified and mathematical functions that describe the normal course of organogenesis of SHR were created, which can be useful
for creating diagnostic algorithms for the norm when carrying out prenatal diagnostics and monitoring the state
of the fetus. It has been established that the 9-10th week of IUD is a critical period in the development of SHR, since
during this time, intensive growth processes occur, which are manifested by a sharp change in the size of the organ,
and this can lead to the appearance of variants of the structure and possible congenital defects of the SHR and the
dental-maxillary apparatus in general.
Conclusions: 1. At the 10th week of the prefetal period of IUD, there is an accelerated increase in the anteroposterior size of the LAP (y = -6.3851 + 1.041 * x; r = 0.9374; p = 0.00001). 2. At the 11th week of the prefetal
period of IUD, there is an accelerated increase in the lateral length of the SHR (y = -6.1289 + 1.1277 * x; r = 0.8891;
p = 0.00001). 3. During the clarification of the regularities of the dynamics of changes in the width of the SHR, it
was found that at the beginning of the prefetal period of the IUD, the growth rates of the indicator are slow, but
from the 9th week of IUD, its accelerated growth is observed (y = -4.5904 + 1.1074 * x; r = 0.8662; p = 0.00001).
4. Features of the change in the value of the anterior angle of SHR in the prefetal period of human ontogenesis
demonstrate a general tendency towards its decrease during this period of development – from 90.18±0.55°
(7th week) to 82.12±1.17 ° (12th week), but after a sharp decrease in this angle until the end of the 8th week of development (79.32±1.03°), its intensive growth begins during the 9th week and until the end of the prefetal period
(y = 93, 8224 – 0.9577 * x; r = -0.4140; p = 0.0229).

Abstract: Abstract
Background: Finding out the sources, the chronological sequence of the germs and the formation of the structure of the human orbit remains a pressing task for morphologists. A comprehensive study of the features of development, formation, topographic and anatomical changes in the structures of the orbit (in particular, the muscles
of the eyeball, blood vessels and nerves), the dynamics of their syntopic changes during the erly prenatal period
of ontogenesis is important to determine the structure, preconditions and time of occurrence of their congenital
malformations
Material and methods: Using a complex of methods of morphological examination 30 series of consecutive
histological sections of human embryos and prefetuses aged from 3 till 8 weeks od IUD (3.0-30.0 mm parietal-coccygeal length (PCL)) were studied.
Results: At the 3rd week of IUD the orbital region is represented by the place of close contact of the neuroectoderm of the optic vesicle with the adjacent integumentary ectoderm, as well as the mesenchyme surrounding this
place of contact. In embryos of 3.5 mm PCL, the rudiment of the optic stalk is observed as a result of the transformation of the junction of the area of the eye rudiment with the brain.
Conclusions: 1. The rudiments of the organ of vision (lens placodes) appear in the 3rd week of IUD. At the
5th week of IUD as a result of gradual intussusception of crystalline placodes into the adjacent mesenchyme, lens
pit are formed, and then – lens vesicles. 2. Rudiments of the extraokular muscles (except for the inferior oblique
muscle) was detected at the end of the 5th week of IUD. The rudiment of the inferior oblique muscle develops from
a single mesodermal islet located in the mesenchyme medially and below the eyeball. Simultaneously with the
rudiments of the extraokular muscles, the trochlear and abductor nerves are develop and ingrown into the orbit.
3. The development of blood vessels of the orbit occurs from two sources – from the islands of local angiogenesis,
which begins in the 5th week of IUD, and from extraorganic vessels, which can be traced in the form of a vascular
network at the end of the 6th week of IUD. The combination of both sources is observed at the end of the 7th week
of IUD. 4. The embryonic period of ontogenesis is the first critical period in the development of the human orbit,
due to the formation of the muscles, nerve and vascular structures.

Abstract: Abstract
renal pyelocaliceal system (RPCS) during the fetal period of human intrauterine development (IUD) is important for elucidating and understanding the complex transformations of their structure, syntopy and skeletotopy,
in particular, to explain the causes and time of appearance of the structural variants and congenital malformations
of the organ.
Material and methods: A total of 102 human fetal biomanikins of 160.0-480.0 mm parietal-coccygeal length
(PCL) (4-10 months of IUD) were studied. A complex of methods of morphological research was applied.
Results: It was found a lobar structure of the kidneys of human fetuses on all specimens. Two main variants of
their external structure were revealed – bean-shaped and oval-shaped. Two variants of the structure of the renal
hilum were observed – their open and compact forms. Among the variants of the structure of the RPCS, we observed
ampullary and branched types. Syntopy of the renal pelvis and pyelo-ureteral segment with renal vessels on the
right and on the left is almost the same, and in the dynamics of the fetal period of IUD does not change significantly.
Conclusions: 1. The topography of the renal calyx-pelvic system is largely determined by the peculiarities of
the spatial structure of the kidney – its external shape, size, skeletotopy, individual features of the hilum of the
organ, their syntopy with the renal vessels.
2. Close syntopy of the renal pelvis and pyelo-ureteral segment with renal vessels with a compact form of the
renal hilum may be an anatomical prerequisite for impaired urodynamics, provided there are variants of renal
vessels branching or the existence of an abnormal vessel in the renal hilum region.
3. Variants of the structure of the kidneys and their structures are clearly observed from the beginning of the
fetal period of human IUD, significantly affect the topography of the calyces and pelvis, and in some cases can cause
impairment of urodynamics.
