Muscle cells produce actin- and myosin protein filaments that go around each other, creating a contraction that affects both the cell's length as well as its shape. Muscles work to create power and movement.The muscle in most species is a soft tissue. Muscle cells produce actin- and myosin protein filaments that go around each other, creating a contraction that affects both the cell's length as well as its shape.
