This picture shows the inside of a single muscle fiber. Click on the link below and watch the video about how the actin and myosin, which are parts inside that individual muscle fiber or the skeletal muscle, work together to create a contraction. This video is very detailed, and it gives you an interactive way to see how the actin and myosin actively work together within this one single muscle fiber to produce shortening or contraction of the muscle.
