{"title":"Effects of skeletal change on muscle pattern formation.","authors":"G Müller","doi":"","DOIUrl":"","url":null,"abstract":"The skeletal influence on muscle development was investigated taking an experimental and comparative approach. Chick hindlimbs of HH stage 23 were operated in order to induce the development of an enlarged, elongated fibula - similar to the condition in bird ancestors. The skeletal change resulted in a series of secondary alterations in the later-forming zeugopod muscles. By comparing the results to the zeugopod musculature in other birds and in reptiles it could be shown that changes did not occur at random but resembled the patterns of interspecific variation and ancestral arrangement. It is concluded that skeletal elements influence muscle morphogenesis during a certain period of development. A classification of four phases in muscle development is presented: formation of the premuscular masses; individuation of separate muscles; final shaping and insertion; development maintenance and growth. The factors acting on each level are discussed and it is suggested that skeletal influence becomes effective in phase 3. The results also emphasize the role of development in evolution. The experimental reestablishment of an ancestral epigenetic condition within a developing organ system resulted in ancestral features of subsequently forming characters. This suggests that modification of epigenetic control of gene expression may be an important mechanism in evolutionary change.","PeriodicalId":75588,"journal":{"name":"Bibliotheca anatomica","volume":" 29","pages":"91-108"},"PeriodicalIF":0.0,"publicationDate":"1986-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14849728","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}

The volumetric growth of these parts shows a nonlinear dependence on age with a smaller increase during the 3d ontogenetic month and a stronger increase from the 4th month on. These data were analyzed together with previous measurements of 28 brains taken from the Yakovlev Collection in Washington, D.C., and the Vogt Collection in Düsseldorf. These brains range in age from 137 to 22,900 days after conception. These samples were reproduced in a model using sigmoid logistic functions. The entire brain and all analyzed parts show a monotonous growth. The individual regions develop heterochronously. The diencephalon is the first part to reach its ideal volume, with a main growth spurt between 100 and 420 days after conception. The rhombencephalon including the cerebellum is the last, with its main growth spurt between 240 and 650 days after conception. The growth of the entire brain is determined to a great extent by that of the telencephalon, having a main growth spurt between 175 and 580 days after conception. The prenatal growth is described separately with the asymmetric sigmoid function according to Gompertz. This yields a better approximation of the data collected from the early prenatal period.","PeriodicalId":75588,"journal":{"name":"Bibliotheca anatomica","volume":" 28","pages":"53-78"},"PeriodicalIF":0.0,"publicationDate":"1986-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14826480","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}
