Smooth muscle contraction (left) requires five steps to perform: After the increase of intracellular Ca2+concentrations from either the extracellular fluid or the sarcoplasmic reticulum (1), these ions bind to a protein called calmodulin (2). We feature over 300+ simulations covering a wide variety of science topics from biology, chemistry and physics through to more specialized sciences including STEM, microbiology and chemical sciences. 4. Smooth muscle contains actin and myosin filaments. Discover the structure and function of cell membranes by launching cargo molecules at a virtual cell. Smooth muscle tissue can be subdivided into two categories depending on whether the cells contract collectively and simultaneously (single-unit smooth muscle) or work independently (multi-unit smooth muscle).
