Unformatted text preview: whereas the myosin filaments are bundles of many myosin molecules. Both the actin and myosin filaments lie parallel to each other. Therefore, when contraction is triggered, the actin and myosin filaments slide past one another in a telescoping manner, thus allowing for muscle cells to contract. Like plasma membranes of neurons, those of muscle cells can generate action potentials. These action potentials that are generated trigger the contractile machinery of the muscle cells. Due to the fact that actin and myosin are the two major proteins in muscle cells, they serve a great deal of importance in muscle contraction as well as for the overall function of an eukaryotic organisms body....
