In a laboratory a section will be produced after the fragments were subjected to a series of procedures. Thus, in most cases, only very small fractions of an organ are analyzed.<br \/>\nFor someone unexperienced it is not easy to assess at what magnification the structures are being visualized with a microscope, in printings or on a screen.<br \/>\nThe measurement unit used to express the dimensions of images of objects obtained with a light microscope is the <strong>micrometer<\/strong>. Its abbreviation is <strong>\u00b5m<\/strong>. One thousand \u00b5m fit into one milimeter (mm), 10 mm fit into one centimeter (cm) and one thousand mm as well as one hundred cm fit into one meter.<\/p>\n<p><strong>Therefore, one micrometer equals to one thousandth of a millimeter and one millionth of a meter.<\/strong><\/p>\n<\/div><\/div>\n  <div class=\"su-column su-column-size-1-2\"><div class=\"su-column-inner su-u-clearfix su-u-trim\"> <\/p>\n<p><img decoding=\"async\" src=\" https:\/\/mol-en.icb.usp.br\/wp-content\/uploads\/1-21-en.jpg \" \/><\/a><\/p>\n<p><a href=https:\/\/mol-en.icb.usp.br\/index.php\/1-22-basic-concepts\/\">NEXT PAGE<\/a><\/p>\n<p><a href=\"https:\/\/mol-en.icb.usp.br\/index.php\/1-20-basic-concepts\/\">PREVIOUS PAGE\u00a0<\/a><\/p>\n<p><a href=\"https:\/\/mol-en.icb.usp.br\/index.php\/1-0-basic-concepts\/\">MENU OF THIS CHAPTER<\/a><\/p>\n<\/div><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-450","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/pages\/450","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/comments?post=450"}],"version-history":[{"count":47,"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/pages\/450\/revisions"}],"predecessor-version":[{"id":21175,"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/pages\/450\/revisions\/21175"}],"wp:attachment":[{"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/media?parent=450"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
