WebThere are three major types of muscle, and their structure reflects their function. Skeletal and cardiac muscle cells are called striated muscle because of the very regular arrangement of their intracellular contractile units, sarcomeres, at the light microscope (LM) and electron microscope (EM) levels. WebSkeletal muscle Skeletal muscle looks striped or "striated" – the fibres contain alternating light and dark bands (striations) like horizontal stripes on a rugby shirt. In skeletal muscle, the fibres are packed into regular parallel bundles. Cardiac muscle Cardiac muscle tissue, like skeletal muscle tissue, looks striated or striped.
