Supraorbital Foramen

Using modern anatomical methods, 57 preparations of human fetuses 4-10 months and 7 newborns were studied in order to create models of distances of supra-, suborbital and chin openings between themselves and to standard landmarks in fetuses and newborns taking into account their morphometric parameters.

Over Time

Numerous anomalies manifested in clinical practice, in most cases, can be explained only on the basis of clarifying the origin and interaction of organs and structures, which over time acquire their characteristic forms, having studied their unusual topography and deeply understanding the corresponding embryonic phenomena. A detailed study of the anatomy of the hand is necessary for a correct under-standing of the pathways of the spread of purulent-inflammatory processes and the development of rational methods of surgical treatment. The prognostication models created to foresee standard morphometric parameters of a palm within a perinatal ontogenesis period are: for the length of a palm = β0+ 0.042 х parietal-calcaneal lengths of a fetus, where β0:= 3.587 during the 4th month of gestation; 5.562 = 5th month; 4.071 = 6th month; 4.840 = 7th month; 6.881 = 8th month; 5.624 = 9th month; 5.448 = 10th month; 5.765 = neonates; for the width of a palm = β0+ 0.038 х parietal-calcaneal length of a fetus, where β0= 2,887 for the 4th month of fetal age; 4.341 = 5th month; 2.638 = 6th month; 3.324 = 7th month; 3.548 = 8th month; 1.714 = 9th month; 1.814 = 10th month; 3.231 = neonates. The proposed models of standard morphometric parameters of a palmar aponeurosis in the perinatal ontogenesis period are the following: for its length – the length of a palmar aponeurosis = β0+ 0.022 х parietal-calcaneal length of a fetus, where β0= 3.531 for the 4th month of the gestational age; 6.532 = 5th month; 6.851 = 6th month; 6.526 = 7th month; 7.583 = 8th month; 7.044 = 9th month; 6.964 = 10th month; 7.968 = neonates; for the width – the width of a palmar aponeurosis = β0+ 0.018 х parietal-calcaneal length of a fetus, where β0= 2.624 within the 4th month of a fetus age; 5.431 = 5th age; 3.701 = 6th age; 4.233 = 7th age; 4.121 = 8th month; 3.602 = 9th age; 3.956 = 10th month; 4.881 = neonates.

Introduction: Normal morphometric parameters of liver in human fetus were studied at various stage of development with an aim to get insight into the normal development of fetal liver. Material & Methods: Dissection of 29 human fetuses was performed. Anthropometric study was done and various parameters were measured. Results: The development of liver is associated with increase in all the parameters although the increase is highly variable in different gestational age, indicating that liver development showed characteristic but highly regulated development to reach its fully developed stage. Conclusion: The present study will be helpful in understanding the normal fetal liver development.

The Right

Defining quantitative growth parameters of individual skeletal bones, namely the right and left femurs, is practically important for determining the age of the fetus. Lack of data on changes in the length of the femur in 4-10 months’ fetuses, as well as the dependence of its morphometric parameters on the length of the lower limb and the age of the fetus, prompted us to conduct this study. The purpose of the study was to determine the morphometric parameters of the length of the right and left femurs during the fetal period of human ontogenesis, which could form the base of normal indicators. Materials and methods. Morphometric study was performed on the lower extremities specimens of 40 human fetuses of an 81.0-375.0 mm parietal-coccygeal length. Results and discussion. As a result of the study, the dynamics of changes in the length of the right and left femurs and lower extremities in 4-10 months’ human fetuses was established. Direct correlations were found in the studied fetal groups, and only in 5-month-old fetuses a direct medium-strength reliable correlation between the lengths of the right and left femurs was found. A weak correlation between the length of the left lower limb and the length of the left femur was found in 7-month-old fetuses. In other cases, direct significant strong correlations were found between the analyzed indicators. The results obtained regarding the change in the length of the right and left femurs, as well as the Pearson correlation coefficient between the morphometric parameters of the length of the right and left femurs and the length of the lower extremities and parietal-coccygeal length of human fetuses 4-10 months are important both theoretically and practically for fetal anatomy. Conclusion. During the fetal period of human ontogenesis, where there is a relatively uniform increase in the length of the right and left femurs, no significant differences in their length were detected. Between the 4th and the 10th month of fetal development, the length of the right femur increases by 5.59 times (from 13.18 ± 2.56 mm to 73.66 ± 2.19 mm), and the length of the left femur increases by 5.44 times: from 13.54 ± 2.35 mm to 73.73 ± 2.12 mm, respectively. In the fetal period the right and left lower extremities also grow equally, no significant differences in their length have been established

It has been reported that explants of human fetal intestine can be maintained in culture for up to 21 days in a viable condition and that these organ cultures support the growth of a variety of known viral agents responsible for enteric disease. Scanning electron microscopy (SEM) has been undertaken on several series of these explants to determine their appearance under routine culture conditions.Fresh specimens of jejunum obtained from normal human fetuses were washed, dissected into l-4mm pieces, and cultured in modified Leibowitz L-15 medium at 34° C as previously described. Serial specimens were fixed each day in 3% glutaraldehyde for 90 minutes at room temperature, rinsed, dehydrated, and dried by the CO2 critical point method in a Denton DCP-1 device. Specimens were attached to aluminum stubs with 3M transfer tape No. 465, and one sample on each stub was carefully rolled along the adhesive such that villi were broken off to expose their interiors.
