Light and electron microscopic examination revealed that some number of muscle fibers were replaced respectively by more than two new fibers after necrosis. These new fibers appear to be derived from the myosatellite cells of the degenerating principal fiber. On day 8, before forelimb appearance, several muscle fibers were observed to contain large vacuoles that were similar in structure to those associated with degenerative muscular diseases such as tenotomized muscles. Semi-serial light microscope observations showed that muscle fibers often split into two fibers during metamorphosis. Such muscle fiber splitting may cause an increase in fiber number in much the same way as the muscular hypertrophy associated with physical exercise in other animals. In conclusion, the observations of fiber replacement and fiber splitting in developing muscles may contribute to the growth of submandibular muscle during metamorphosis.","subitem_description_type":"Abstract"}]},"item_3_description_4":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"原著","subitem_description_type":"Other"}]},"item_3_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"群馬県立県民健康科学大学紀要 5,11-17,2010","subitem_description_type":"Other"}]},"item_3_publisher_13":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"群馬県立県民健康科学大学"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1881-0691","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_8":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12136570","subitem_source_identifier_type":"NCID"}]},"item_3_version_type_10":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"神宮司, 洋一"}],"nameIdentifiers":[{"nameIdentifier":"395","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"白石, 明久"}],"nameIdentifiers":[{"nameIdentifier":"396","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jinguji, Yoichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"397","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Siraishi, Akihisa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"398","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-03-09"}],"displaytype":"detail","filename":"KJ00005989079.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00005989079.pdf","url":"https://gchs.repo.nii.ac.jp/record/46/files/KJ00005989079.pdf"},"version_id":"c355db1e-4ff9-45e5-8c48-bbdc5b04eb07"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"アカガエル","subitem_subject_scheme":"Other"},{"subitem_subject":"下顎筋","subitem_subject_scheme":"Other"},{"subitem_subject":"変態","subitem_subject_scheme":"Other"},{"subitem_subject":"筋再生","subitem_subject_scheme":"Other"},{"subitem_subject":"筋線維分岐","subitem_subject_scheme":"Other"},{"subitem_subject":"Rana japonica","subitem_subject_scheme":"Other"},{"subitem_subject":"submandibular muscle","subitem_subject_scheme":"Other"},{"subitem_subject":"metamorphosis","subitem_subject_scheme":"Other"},{"subitem_subject":"muscular regeneration","subitem_subject_scheme":"Other"},{"subitem_subject":"muscle fiber splitting","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"アカガエル変態期の下顎筋でみられた筋再生と筋線維分岐","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"アカガエル変態期の下顎筋でみられた筋再生と筋線維分岐"}]},"item_type_id":"3","owner":"2","path":["16"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-02-17"},"publish_date":"2012-02-17","publish_status":"0","recid":"46","relation_version_is_last":true,"title":["アカガエル変態期の下顎筋でみられた筋再生と筋線維分岐"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-06-28T07:25:37.809063+00:00"}
