It is found throughout the urinary system where it functions to help rid the body of toxins and works in electrolyte balance. It is found throughout arteries and veins where it …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. This regular arrangement imparts a cross-striated (or striped) appearance.Each skeletal muscle fiber is a skeletal muscle cell. These cells are incredibly large, with diameters of up to 100 µm and lengths of up to 30 cm. The plasma membrane of a skeletal muscle fiber is called the sarcolemma. The sarcolemma is the site of action potential conduction, which triggers muscle contraction.The cells are interconnected physically and electrochemically to act as a syncytium.
