However, it also functions as a platform for inter- and intracellular signaling, linking the contractile apparatus so that sarcomeres may function in ... There 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.
