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:
o myosin
o actin
o anchors
o dense bodies
o troponin

Explanation:

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

Answer:

dense bodies
