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

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.

Abstract Like all multi-authored texts, the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides) presents some challenges and inconsistencies, and in March 2002 AMA published an errata. The latter has only one correction for Chapter 17, The Lower Extremities, and this article reviews some additional problems and inconsistencies in Chapter 17. For example, the AMA Guides, Fifth Edition, gives inconsistent instructions about measurements of muscle atrophy, and this article recommends simple, unambiguous directions such as measuring thigh and leg circumferences 15 cm superior and inferior to the medial joint line of the knee, respectively. One could argue that no goniometer should be included in Figure 17-1a, Using a Goniometer to Measure Flexion of the Right Hip; in Figure 17-1b, the goniometer should be placed with its axis at the center of rotation of the right hip. In Figure 17-1c, the limb of the goniometer overlying the left femur should instead be parallel to the tabletop. Additional sections of the article discuss joint ankylosis; peripheral nerve injuries; causalgia, complex regional pain syndrome, and reflex sympathetic dystrophy. A careful reading of Chapter 17 uncovers some problems, none of which is critical, but all should be noted by frequent users of the AMA Guides.

Morphological Research

In-depth study of the peculiarities of the morphological, topographic and anatomical relationships between fascia, muscles, vessels, nerves, cellular spaces and organs of other parts of the human body requires applying an appropriate methodology of morphological research. According to some researchers, the superficial, pretracheal, and prevertebral plates of the cervical fascia develop depending on the origin and morphogenesis of the respective groups of neck muscles. Obtaining data on the development of topographic morphology of the cervical fascia and interfascial cellular spaces of the anterior and lateral areas of the neck during the fetal period of human ontogenesis is an important area of fetal anatomy and surgery and can be used for age comparison. The purpose of the study was to clarify the peculiarities of the development of the topographic morphology in the cervical fascia and interfascial cellular spaces of the anterior and lateral areas of the neck in human fetuses of 4-10 months of gestation. The study was performed on 75 human fetuses of 81.0-375.0 mm parietal coccygeal length without external signs of anatomical abnormalities or developmental anomalies of the cervical region by preparing microscopic slides of organs and structures of the anterior and lateral areas of the neck. The samples taken from fetuses weighing more than 500.0 g were investigated directly at the Chernivtsi Regional Paediatric Pathological Bureau according to the association agreement. The material was also taken from the M.G. Turkevich Museum of the Human Anatomy Department, Bukovinian State Medical University. The macroscopic and microscopic investigation of the cervical region in human fetuses of 4-7 months revealed thin, semitranslucent plates of the cervical fascia: superficial, middle (pretracheal) and deep (prevertebral). In fetuses of 8-10 months in the anterior area of the neck, the plates of the cervical fascia were clearly seen and shiny. Subcutaneous, or superficial, and intracervical fascias were fascias propria of the neck, and having no clear boundaries passed into adjacent areas. In the fetal period of human ontogenesis the interfascial cellular spaces of the anterior and lateral areas of the neck develop including suprapectoral, anterovisceral, extravisceral, antescalenous, interscalenous cellular spaces and sheath of vascular-nervous bundles of the neck. During the fetal period of human ontogenesis, there is a pronounced variation in the development and location of the plates of the cervical fascia. The authors of this study state that the research and result publication have no conflicts regarding commercial or financial relations, relations with organizations and/or individuals who may have been related to the study.

The aim: Is to find out the features of innervation of the skin of the anterior femoral region and the fascia lata during the fetal period of human development. Materials and methods: The study was carried out on 64 preparations of the lower extremities of human fetuses of 4-10 months using macromicroscopic preparation and morphometry. Macropreparations of the skin nerves of the lower extremities of different age fetuses with anatomical variants were subject to photo documentation. Results: The features of cutaneous nerve fetal topography of the anterior femoral region and the broad fascia of the femur were revealed, their connections were established, and their layering was determined. It was found that in human fetuses, not only the lateral cutaneous femoral nerve but in most cases the branches of other nerves of the lumbar plexus, except for the obturator nerve, are directed to the skin of the anterior-lateral femur surface. The innervation of the medial femur surface is provided by the following nerve complex: obturator, femoral, saphenous and genitofemoral nerves. Conclusions: Taking into account the fact that the terminal branches of adjacent cutaneous nerves of the femoral region intersect and overlap, innervation bypasses are formed, due to which, in case of possible damage to one of the nerves, its insufficiency is compensated to a certain extent. Anastomoses were found between the cutaneous nerves, in the form of loops of various shapes and sizes, namely: between the cutaneous-fascia branches of the femoral and ilioinguinal nerves and the femoral and obturator nerves.

The Yemeni honeybee (Apis mellifera jemenitica Ruttner) is the native race in Saudi Arabia. The Carniolan honeybee (A. m. carnica Pollmann) and its hybrid with the Egyptian honeybee (A. m. lamarkii Cockerell) have been imported and frequently reared in Saudi Arabia. Temperature often exceed 40 °C during the summer season in most regions of Saudi Arabia. Honeybees decrease foraging activity in this period during mid-day, which affect colony productivity. The Yemeni bee race appears well adapted to these unique climatic conditions. We compared body weight and morphometric parameters of both subspecies’ worker bees reared at the apiary of Training and Research Station, King Faisal University, Al-Ahsa oasis of eastern Saudi Arabia. Measurements of Yemeni bee were smaller than Carniolan bee for body weight, head structures, including antenna, flagellum, and proboscis length, thorax appendages, including femur length, tibia length and width, metatarsus length and width of the right hind leg, and length and width of the right forewing and hind wing, abdominal characteristics, including the length of the 3rd and 4th abdominal tergites and sternites, and length and width of the 1st and 4th wax mirrors. It could be concluded that with the exception of the number of hamuli, worker Yemeni bee body size and morphometric parameters related to the colony productivity were smaller than Carniolan bees under environmental conditions of the study region.

: Knee deformities can be reliably assessed by using morphometric parameters of upper end of tibia. Total knee arthroplasties are done to treat many types of arthritis and injuries involving knee joint. So, there is a need to have data of various morphometric parameters of upper end of tibia in order to have better surgical outcomes. The present study was attempted to provide values of different parameters in the population of Bihar.: The present study was a cross-sectional and prospective study conducted on 50 tibia of unknown gender and age in the Department of Anatomy, Indira Gandhi Institute of Medical Sciences, Patna. Fully ossified, dried, macerated and thoroughly cleaned tibia were taken to measure different parameters of upper end with the help of digital vernier calliper. The data thus obtained were tabulated and analysed statistically using Microsoft excel software.: It was found that the diameters of medial condyle were more than the lateral condyle. The antero-posterior diameter was more than the transverse diameter in case of both the condyles. But the difference between the right and the left side was not statistically significant.: The present study will help in providing a baseline data for designing of the prosthesis used in total knee replacement surgeries. It will also be helpful to anthropologists and forensic experts.

AbstractMorphometric methods were used to study hearts with perimembranous ventricular septal defects in 22 human fetuses and neonates weighing from one to 3.8 kg (2.221±0.852 kg). All specimens displayed concordant atrioventricular and ventriculoarterial connections, and all had perimembranous ventricular septal defects. A total of 17 interventricular parameters (nine in the right ventricle and eight in the left) were measured in each specimen. The values were compared with patterns of normality established by Rowlatt and her colleagues in hearts from 83 children ranging in age from birth to 15 years. These patterns were found to be less reliable than our own data from fetal and perinatal hearts from children ranging in age from birth to one month. Our morphological data, when appropriately interpreted, have immediate clinical and surgical applications in the treatment of fetal and perinatal cardiovascular disorders.

BACKGROUND: The stability of a joint depends on the arrangement of the articular surfaces. Thefailure of acetabulum to deepen along with associated relaxed capsule can be a causative factor leadingto congenital dislocation of hip in babies. The right traumatic hip dislocation is less uncommon ascompared to left side in adults.OBJECTIVE: To correlate the majority of right-footed population with the bony parameters of hipjoint bilaterally and to find out its association with left congenital and right acquired traumaticdislocation of hip.MATERIAL AND METHODS: As the right footed people are considerably more (90%) than the leftfooted and this study work was correlated with the bones collected from cadavers in Anatomydepartment of KGMC Peshawar from January 2014 to December 2014. We included 14 pairs of femurs,14 pairs of hip bones in this study to see the structural differences when dominant hip joint is comparedwith non-dominant hip joints. The measurements were performed with the help of vernier caliper.RESULTS: The mean horizontal diameter of right (dominant) and left acetabulum was 50.14±0.69 mmand 52.35±0.65mm. The mean horizontal depth of right and left acetabulum was 22.21±0.82mm and25.25±0.52mm. The horizontal diameter of right and left femur was 46.42±0.62mm and 43.85±01mm.The thickness of femoral head was 26.71±01mm on right (dominant) side but this thickness was29.17±01mm on left side.CONCLUSION: The left acetabulum was having a significant larger diameter in adult, allowing thesmaller left femoral head to fit snugly which can be correlated with the more common left congenitaldislocation hip. On the other hand, in adults, the left acetabulum is deeper, allowing the thicker left headof femur as an adjustment for weight bearing functionwhile the larger rightfemoral head fit into acomparatively shallow socket. This may be a factor to improve mobility at the cost of stability; as righttraumatic dislocationhip is less uncommon as compared to left side.KEY WORDS: Hip joint, Ball and socket joint.

The aim of this work is to elucidate the features of morphogenesis, syntopic and morphometric changes in the structures of the orbit, neurovascular and muscular structures of the organ of vision in the fetal period of human ontogenesis.Material and methods. By means of complex of methods of morphological research (anthropometry, morphometry, microscopy, preparation, three-dimensional computer reconstruction and statistical analysis), 30 specimens of human fetuses of both sexes aged from 4 to 10 months of intrauterine development (IUD) (160.0-460.0 mm parietal-coccygeal length (PCL)) were studied. Computer tomography was used to study 17 human fetuses aged from 4 to 9 months of IUD (180.0-440.0 mm PCL).Results. At the end of the 5th month of IUD, an orbital index is 75%, which is noted in the transformation of the shape of orbit from flattened to rounded due to an increase in its vertical size relative to the horizontal one. We associate this transformation of the orbit with syntopic influence of adjacent regions: the growth of the lateral wall of the nasal cavity, development of the paranasal sinuses, and facial skeleton. At the end of the 5th week of intrauterine development, external eyeball muscles are finally differentiated from the common muscle rudiment. The analysis of changes in morphometric parameters of muscles of the eyeball made it possible to derive mathematical functions, that describe normal dynamics of growth of their length, as well as to reveal critical periods of their development in terms of the rate of changes in their thickness and width.Conclusions1. The development of the organ of vision in the fetal period of human ontogenesis is a complex process due to the coordinated interaction between morphological and morphometric changes in the orbit, eyeball and its muscles, nerves and vessels.2. Critical periods of development of the orbit and its structures is the 6th month of intrauterine development, during which there is an uneven growth rate of the size of the muscles of the eyeball, as well as the size of the orbit.3. At the 6th month of intrauterine development, uneven growth rates of the horizontal size of the orbit relative to the vertical one are observed, as a result of which its shape begins to return to the mesoconchal type characteristic of such prefetuses. Such age-related transformations of shape and size of the orbit are due to the growth of the eyeball, skull and face, which generally determines the shape of the orbit.4. Starting from the 8th month of fetal period of development, structure and topography of the structures of the orbit acquire signs of a definitive condition, the shape of the orbit is finally established, and uniform growth rates of all structures of the organ of vision are observed, except for the growth of the circumference of the orbit at the end of prenatal period of human ontogenesis.
