Question

multiple choice question
in smooth muscle fibers, the thick filaments do not attach to the thin filaments to produce shortening of the fiber. instead, the thin filaments are anchored directly to the sarcolemma or to protein molecules called:
○ actin
○ anchors
○ troponin
○ myosin
○ dense bodies

Explanation:

In smooth - muscle fibers, thin filaments are anchored directly to the sarcolemma or to protein molecules called dense bodies. Actin is a component of thin filaments, myosin is of thick filaments, troponin is associated with thin filaments in striated muscle for regulation, and "anchors" is a non - specific term here.

Answer:

E. dense bodies
