Its nutrients and oxygen reach the chondrocytes by diffusion of substances originated from blood vessels placed nearby through its ECM.<br \/>\nBecause of this way of nutrition the cartilage pieces are usually small and thin. The distances that nutrients, metabolites, and gases must travel within the ECM to reach the chondrocytes are short.<br \/>\nMost cartilage pieces are covered by a layer of dense connective tissue called <strong>perichondrium<\/strong>.<\/p>\n<p>The figure shows examples of the distribution of cartilages in the body:<\/p>\n<p>1- Articular surfaces \u2013 hyaline cartilage<br \/>\n2- Epiphyseal discs (growth zones of long bones) \u2013 hyaline cartilage<br \/>\n3- Auricles of the ear \u2013 elastic cartilage<br \/>\n4- Nose \u2013 hyaline cartilage<br \/>\n5- Epiglottis \u2013 elastic cartilage<br \/>\n6- Larynx \u2013 hyaline and elastic cartilage<br \/>\n7- Trachea \u2013 hyaline cartilage<br \/>\n8- Extrapulmonary and intrapulmonary bronchi \u2013 hyaline cartilage<\/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\/6-2.jpg \" \/><\/a><br \/>\n<strong><\/p>\n<p><a href=https:\/\/mol-en.icb.usp.br\/index.php\/6-3-cartilage\/\">NEXT PAGE<\/a><\/p>\n<p><a href=\"https:\/\/mol-en.icb.usp.br\/index.php\/6-1-cartilage\/\">PREVIOUS PAGE <\/a><\/p>\n<p><a href=https:\/\/mol-en.icb.usp.br\/index.php\/6-0-cartilage\/\">MENU OF THIS CHAPTER<\/a><br \/>\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-3015","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/pages\/3015","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=3015"}],"version-history":[{"count":18,"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/pages\/3015\/revisions"}],"predecessor-version":[{"id":25481,"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/pages\/3015\/revisions\/25481"}],"wp:attachment":[{"href":"https:\/\/mol-en.icb.usp.br\/index.php\/wp-json\/wp\/v2\/media?parent=3015"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
