The dense bodies of the smooth muscle act as anchoring points for the thick filaments and therefore correspond to the z discs of the skeletal muscle.
true or false?

True

Explanation:

In smooth muscle, actin filaments are attached to the dense bodies on the plasma membrane and within the cytoplasm. These dense bodies are the functional equivalent of Z-disks in skeletal and cardiac muscle. ... These caveolae are analogous to the T-tubule system in skeletal muscle fibers
