Smooth muscle
The myofilaments of smooth cell fibers are not organized into myofibrils; instead, the overlapping thick and thin filaments form a reticulum within the sarcoplasm. Actin filaments are anchored in dense bodies, which represent Z lines of striated muscle. Dense bodies are located both in the sarcoplasm and beneath the sarcolemma. 7000x
