They have a non-striated appearance and contract involuntarily.<\/p>\r\n\r\n<p><strong>Cardiac muscles<\/strong> are found in the walls of the heart. They also contract involuntarily, but have a striated appearance.<\/p>\r\n\r\n<p><strong>Skeletal muscles<\/strong> are attached to, and move, bones. These muscles contract voluntarily and have a striated appearance. Skeletal muscles are sub-categorized into 4 distinct groups, based on the orientation and arrangement of the muscle fibres:<\/p>\r\n<ul>\r\n\r\n\t<li><strong>Parallel skeletal muscles<\/strong> consist of fibres that are arranged in parallel to the line pulled during contraction. Parallel muscles can be sub-categorized based on their shape, into:\r\n<ul>\r\n<li>Quadrilateral (eg. the pronatur quadratus)<\/li>\r\n<li>Strap-like (eg. the sartorius)<\/li>\r\n<li>Fusiform (eg. the brachioradialis)<\/li>\r\n<\/ul><\/li>\r\n\r\n\r\n\t<li><strong>Convergent muscles<\/strong> contain fibers that have a wide origin, but converge in order to attach to a narrow tendon.<\/li>\r\n\r\n\r\n\r\n\t<li><strong>Circular skeletal muscles<\/strong> are made up of fibers that are arranged in a circular manner. They are found at points of openings, where contraction leads to a closure of that opening.<\/li>\r\n\r\n\r\n\r\n\r\n\t<li><strong>Pennate skeletal muscles<\/strong> consist of muscle fibres that are attached to the sides of a tendon, in a manner that is similar to a feather. Pennate muscles can be sub-categorized based on their shape into:\r\n<ul>\r\n\t<li>Unipennate (eg. the flexor policis longus)<\/li>\r\n\r\n\t<li>Bipennate (eg. the rectus femoris)<\/li>\r\n\r\n\t<li>Multipennate (eg. the deltoid)<\/li>\r\n<\/ul><\/li><\/ul>\r\n\r\n<p><strong>Explore the minute details of the muscular system in Complete Anatomy with a suite of 3D learning features such as Muscle Motion, Innervation, Origin\/Insertion maps and more. <a href=\"https:\/\/completeanatomy.cn\" target=\"_blank\" rel=\"noopener\">Try it for free today<\/a>.<\/strong><\/p>","protected":false},"excerpt":{"rendered":"<p>3 types of muscles are contained within the human body: Smooth, Cardiac and Skeletal.<a class=\"more-link\" href=\"https:\/\/corpsite.nonprod.completeanatomy.cn\/es\/blog\/muscular-system\">Leer art\u00edculo<\/a><\/p>\n","protected":false},"author":9,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[317],"tags":[],"acf":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/corpsite.nonprod.completeanatomy.cn\/es\/wp-json\/wp\/v2\/posts\/9199"}],"collection":[{"href":"https:\/\/corpsite.nonprod.completeanatomy.cn\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/corpsite.nonprod.completeanatomy.cn\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/corpsite.nonprod.completeanatomy.cn\/es\/wp-json\/wp\/v2\/users\/9"}],"replies":[{"embeddable":true,"href":"https:\/\/corpsite.nonprod.completeanatomy.cn\/es\/wp-json\/wp\/v2\/comments?post=9199"}],"version-history":[{"count":1,"href":"https:\/\/corpsite.nonprod.completeanatomy.cn\/es\/wp-json\/wp\/v2\/posts\/9199\/revisions"}],"predecessor-version":[{"id":22470,"href":"https:\/\/corpsite.nonprod.completeanatomy.cn\/es\/wp-json\/wp\/v2\/posts\/9199\/revisions\/22470"}],"wp:attachment":[{"href":"https:\/\/corpsite.nonprod.completeanatomy.cn\/es\/wp-json\/wp\/v2\/media?parent=9199"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/corpsite.nonprod.completeanatomy.cn\/es\/wp-json\/wp\/v2\/categories?post=9199"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/corpsite.nonprod.completeanatomy.cn\/es\/wp-json\/wp\/v2\/tags?post=9199"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
