The aim of this paper is to summarise the knowledge about the anatomy, embryology and anthropology of the mandible and the mandibular foramen and also to highlight the most important clinical implications of the current studies regarding anaesthesia performed in the region of the mandible. An electronic journal search was undertaken to identify all the relevant studies published in English. The search included MEDLINE and EMBASE databases and years from 1950 to 2012. The subject search used a combination of controlled vocabulary and free text based on the search strategy for MEDLINE using key words: ‘mandible’, ‘mandibular’, ‘foramen’, ‘anatomy’, ‘embryology’, ‘anthropology’, and ‘mental’. The reference lists of all the relevant studies and existing reviews were screened for additional relevant publications. Basing on relevant manuscripts, this short review about the anatomy, embryology and anthropology of the mandible and the mandibular foramen was written. (Folia Morphol 2013; 71, 4: 285–292)
Investigation into the bony pelvis of the fruit-eating bat, Eidolon helvum, revealed differences in the pelvic dimensions. The pubic joint of the female consists of interpubic ligament that increased in length until puberty. In the juvenile male Eidolon the pubic joint consists of ligament. Ossification of the interpubic ligament in the male is not an adult phenomenon but begins at the juvenile stage. In the adult the distance from the ischial tuberosity to the iliac crest, from the ischial tuberosity to the medial end of the pubis, and the outlet anteroposterior diameter of the pelvis, were significantly higher in the male than in the female. This indicates that the hip bone in the male is longer in both the vertical (height) and transverse (width) measurements than in the female. The dimensions of the adult pelvic inlet and outlet transverse diameters were significantly higher in the female than in the male. This indicates that the female pelvic canal is wider than the male and this is a consequence of the female interpubic ligament.
For many years, students of various backgrounds have been subject to research, including the anthropological studies. The second half of the 20 th century under - went a change in the anthropological view on the somatic race selection of pupils from various types of schools and faculties. The major aim of this work is to present the typological diversity of female students in the science faculties at the University of Rzeszów in the face of Kretschmer. There were the following specific aims: research in the influence of the social environment on the somatic structure of the female students, specification of the influence of the body structure and the social environment on the menarche of the surveyed students and the comparison of the results to the results of the authors in other academic centers in Poland. 2009/2010, 143 randomly chosen students of the Biological and Agricultural Studies at the University of Rzeszów were researched. Only full time course students were subject to the research. The standing position concerned the following measurements: body height (B-y), shoulders girth n(a-a), coxal girth (ic-ic), chest girth (at xi) and bodyweight. For each of the feature, the following parameters were taken: arithmetic mean ( X) standard deviation (Sd), variance (Sx), variation coefficient (V), minimum and maximum values. Based on those values, the body features of the students of various social origins and university specializations were compared. The evaluation of the statistical significance of the differences in the results of the students and the age of menarche of the students from cities compared to villages was conducted using t-Student test (p < 0,05).The somatometrical results showed the following indicators: Rohrer indicator, growth and shoulder indicator, chest girth indicator, BMI indicator aso-called “Kretschmer’s indicator”. On the basis of the above-mentioned indicators (excluding the BMI indicator), according to Kretschmer’s typology, the following female students’ body structures were specified. The survey data provided social and environmental birth order and the age of students’ menarche (the retrospective method): 1) The vast majority of the students of thee science faculties of the University of Rzeszów have the leptosomic body structure; 2) Students living in the village usually have wider shoulders and wider chest girths than the students living cities. Students living in villages are also heavier; 3) Sthenic-built women mature earlier, while women who have leptosomic body structure mature later; 4) Women students of the University of Rzeszów do not differ from other female students in Poland; 5) No relation between the place of living and the age of menarche was observed; 6) The students of the University of Rzeszów surveyed in 2009/2010 had heavier body structures than the students of 1999/2000.
This study analyses, using selected somatometric features, secular trend changes which have occurred over a quarter of a century in female and male students of the Medical University of Łódź. The study is based on the results of an anthropometric survey carried out among first-year students who commenced their studies in the academic years 1978/79 (240 females and 193 males), 1982/83 (347 females and 188 males), 1988/89 (178 females and 165 males) and 2003/04 (188 females and 77 males). The following features were examined in all participants in the survey: body height (B-v), the height of the lower body segment measured from a floor base to the crista iliaca at the point on the mid-axillary line (B-ic), shoulder width (a-a), intertrochanteric distance (tro-tro) and resting chest circumference. To compare average values Student’s t-test was used with assumptions of equal and unequal variances. To gauge the magnitude of changes in specific features in the course of a quarter of a century a percentage difference in results was calculated for the years 2003/2004 and 1978/1979. The basis for the calculations was the initial value of a feature at the beginning of the period analysed. It was determined that in the 25-year period analysed (1978–2003) the young people commencing studies at the Medical University of Łódź exhibited an acceleration in the height of the lower body segment (B-ic) and of the intertrochanteric distance (tro-tro) and a deceleration in resting chest circumference. Additionally, an increase in shoulder width has been noted in female students; no significant intergenerational changes were noted in body height, although the last 15 years display certain symptoms of deceleration; there is an emerging tendency towards a blurring of the differences in body proportions between the sexes in the environment of the young people studying at the Medical University of Łódź.
