| Calcium along with phosphorus and carbonate imparts hardness and strength to skeletal system. Most of the human studies in this context are based on informations in postnatal life. There are different theories to explain the manner in which the matrix of bone becomes impregnated with the two inorganic salts, calcium phosphate and calcium carbonate. In our study, 29 human foetuses were obtained from the museum section of Department of Anatomy, J .N. Medical College, Aligarh, and divided into five groups. Maxillae were cleaned by separating the soft tissue and dissolved in concentrated nitric acid to determine calcium. Results were analysed by using Student's 't' test. The most striking feature of our findings was a reduction in aforementioned relative... |

| This comparative study of gill morphometrics in near-term embryos of freshwater stingray potamotrygonids examines gill dimensions in relation to neonatal lifestyle and habitat. In embryos of the potamotrygonids Paratrygon aiereba, Plesiotrygon iwamae, Potamotrygon motoro, Potamotrygon orbignyi, and cururu ray Potamotrygon sp. the number and length of filaments, total gill surface area, mass-specific surface area, water-blood diffusion distance, and anatomical diffusion factor were analysed. In all potamotrygonids, the 3rd branchial arch possessed a larger respiratory surface than the other gill arches. Larger embryos had more gill surface area and large spiracles, which are necessary to maintain the high oxygen uptake needed due to their larger body size.... |

| Foetal therapy has made foetal anatomy a promising field. Maxilla had been the core research attraction of many scientists. Alveolar arches, specially the maxillary one had been consistently the focus of attention for research workers due to its importance in dentistry. Twenty nine human foetuses were grouped into I (<24 weeks of IUL), II (25-30 weeks of IUL) and III (>30 weeks of IUL). Maxillae were dissected out and sockets were carefully cleaned. Sockets for the temporary molars, which also hold permanent premolars were measured with the help of Vernier callipers. Three parameters, i.e. maximum mesiodistal diameter,maximum transverse diameter and maximum depth were considered. Readings were analysed statistically by using Student's 't' test.... |
