The simpliest synarthrosis is represented by a (visco-)elastic disk that connects two rigid bodies. Diarthroses and synarthroses are statically distinguished by the character of force transfer. Because of their adhesive connection to the corresponding bony structures synarthroses can transfer shear stresses while diarthroses can only be loaded by forces which act normal to their functional surfaces. Therefore, the interface between the body structure and the elastic synarthrosis can be considered as a surface of infinite static (adhesive) friction, while the contacting surfaces in a diathrosis possess vanishing static friction. Kinematically, the difference between diarthroses and synarthroses is established by the fact that diarthroses possess axes of rotation which are approximately fixed relatively to the morphology of the corresponding functional surfaces while in synarthroses the positions of rotational axes depend on the geometric structure of the applied and transferred force system. The first part entire paper presents the most simple module of a diarthrosis, the kinematically open dimeric link chain.","PeriodicalId":72195,"journal":{"name":"Anatomischer Anzeiger","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13350951","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":"Immunocytes in the human fetal pancreas--a contribution to developmental immunoendocrinology concerning diabetes mellitus and organ cultivation.","authors":"H Hahn von Dorsche, K Fält","doi":"","DOIUrl":"","url":null,"abstract":"The studies were performed on 103 samples of human fetal pancreas tissue (10th to 26th week of gestation). Of the mothers, 14 had insulin dependent type I diabetes mellitus (IDDM), and 33 of the samples were examined before and after cultivation for 14 days. 3 samples taken from fetuses in the 14th week of development (mothers without metabolic disorders) were examined in the electron microscope. Lymphocytes are generally irregularly distributed within the tissue. Groups of 3 to 5 lymphocytes are found in addition in the 12th week of development, and larger clusters (10 to 15 lymphocytes) appear from the 14th week onward. Relating these quantitative results to the 3 phases of early fetal islet organ development, it can be seen that lymphocyte numbers increase from the 10th to the 26th week of development. The significance of this is discussed in connection with the development of the immune system. In view of the contemplated transplantation of fetal pancreas tissue as treatment for IDDM, it means that a relatively low immunogenicity can be expected up to the 14th week of development. Thymic differentiation is not complete before the 17th week, and differentiation of the lymph nodes and spleen continues until weeks 20 to 23. Although IgG antibodies are transferred across the placental barrier already in about the 8th week, this flux does not reach its maximum until the 32nd week. Endogenous antibody synthesis in the fetus does not start until the 18th week. IDDM of the mother during fetal development (10th to 26th week) does not increase the lymphocyte number in the pancreas. This also applies to tissue that has been cultivated for 14 days after reaching the same stage of development.","PeriodicalId":72195,"journal":{"name":"Anatomischer Anzeiger","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13411138","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":"[Age characteristics of the normal human skeletal musculature--mathematical description of postnatal skeletal muscle growth].","authors":"J B Ziegan, G Sager","doi":"","DOIUrl":"","url":null,"abstract":"The number of muscle fibres per mm2 is age dependent, and therefore briefly denoted as age specific number (Alterskennzahl AK). We determined the AKs for the age groups up to 25 years, separated after the sexes and for M. vastus lateralis et deltoideus. According to the trend of the original data the approximations have been carried out applying 4 functions of organismic growth in modified form, i.e. the Pütter (1920), Bertalanffy (1934), Richards (1959), Janoschek extended by Sager (1984) and Richards extended after Sager (1980). Curve fitting is reached by regression analysis and nonlinear regressions using the sums of the linear deviations as a criterion for the goodness of fit. Results including initial as well as final values are summarized in tables with the parameters of the calculation methods added. The AKs allow judging the degree of maturity in the skeletal musculature during childhood. Transposing of the equations for AK = W yields t as a function of the normally adjunctive age specific number. The difference against real age reveals to which degree the musculature is eventually underdeveloped. Concerning the interpretation the fact should be kept in mind that biological processes are involved. The relation of the fibre types too implies a characteristic age dependency. This statement and the fibre diameters gained from the same material allow a mutual control and an exact fixation in each case.","PeriodicalId":72195,"journal":{"name":"Anatomischer Anzeiger","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13484318","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}
