The apex of the sublingua ends in two lobe-like projections separated by a distinct median cleft. The lobes exhibit at their oral, free margin tiny processes, but no \"comb\"-like specializations of intensely keratinized mucosa. At the ventral surface of the sublingua three longitudinally oriented keels or ridges are found; the mucosa of the keels is strongly keratinized, so that these structures maximize the rigidity of the undertongue. In none of the specimens examined was any trace of sublingual cartilage found; in the sublingua of Cheirogaleus (only one individual examined), the nearest relative of Microcebus, cartilage was also absent. The absence of sublingual cartilage and the incidental, irregular occurrence of cartilaginous elements in the sublingua of Tarsius and Tupaia indicate that the sublingual cartilaginous skeleton is not a derivative of the hyoid arch. It is a newly developed supporting structure which does not regularly occur. A sublingua occurs only in prosimians and Tarsius; whether the fimbria linguae of the Hominoidea is the homologue of a sublingua is still disputable. The exclusive occurrence of a sublingua in prosimians and Tarsius indicates a phylogenetic relationship between these two groups and Tupaia. The \"Tupaia-problem\" concerns the origin of primates and from this point it derives its general importance. At present we are far from a final solution; a definite answer cannot be expected before sufficient fossil records are available which document conclusively the historical paths of the origin of primates.","PeriodicalId":76854,"journal":{"name":"Zeitschrift fur Morphologie und Anthropologie","volume":"78 1","pages":"25-42"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13745538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Developmental relations between the weight of internal organs and somatic features of fetuses and newborns.","authors":"B Marecki","doi":"","DOIUrl":"","url":null,"abstract":"The paper contains results of investigations on statistical developmental interrelations between the weight of brain, heart, lungs, liver, spleen, kidneys, adrenal glands and thymus, and the total length, the crown-rump length and the body weight, and the circumference of head, shoulders, chest and abdomen of fetuses and newborns in the age from 17 to 43 weeks of life. The character and the force of the relations between the degree of the development of the weight of organs and the body dimensions was investigated by statistical methods on three levels. On the basis of the value of linear correlation coefficients, statistical relations were determined between the weight of the particular organs and the particular sometic features. The dependence between the particular organs and the complex of somatic features was determined on the basis on the multiple regression analysis. On the other hand the relation between two complexes of features, i.e. all organs and all somatic features was investigated with the help of canonical correlation coefficients. The analysis of results indicated that between the weight of internal organs and the somatic features in the fetal period there exists a statistical developmental relation. The developmental relations are most strongly marked between the 6th and the 10th months of intrauterine life, while in the 5th month of life and in postmature fetuses and newborns they are weaker.","PeriodicalId":76854,"journal":{"name":"Zeitschrift fur Morphologie und Anthropologie","volume":"78 1","pages":"107-15"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13747200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper some common developmental standards used in the determination of fetal age are reviewed. The standards, as found in the relevant literature, are tested against a control group for their accuracy in predicting fetal age. The results indicate considerable discrepancy among the various standards. Further, the developmental ages defined by these standards often differ considerably from the known menstrual age. My own attempt to present a more reliable set of developmental standards is based on the analysis of three morphological features commonly used in biological assessment. Body weight, crown-heel length, and crown-rump length are measured in weekly termed groups representing the 20th-42nd weeks of intrauterine life. The accuracy of body weight and crown-heel length in predicting fetal age is tested both within and against a control group. Statistical analysis show no significant differences between the predicted and known fetal ages. These results indicate that body weight and crown-heel length are reliable developmental standards from which fetal age can be defined.","PeriodicalId":76854,"journal":{"name":"Zeitschrift fur Morphologie und Anthropologie","volume":"78 1","pages":"133-42"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13745536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
