Question

Quizplus · Accepted Answer

Skeletal, cardiac, and smooth muscle all contain thick and thin filaments, which are responsible for muscle contraction. A bands and I bands are specific structures found in skeletal and cardiac muscle, but not in smooth muscle. Transverse tubules and motor units are specific to skeletal muscle. Gap junctions are specific to cardiac and smooth muscle. Therefore, thick and thin filaments are the best choice as the common feature among all three types of muscle.
