Voluntary muscle contraction visualization showing the interaction between myosin heads and actin filaments. Beginning outside of a generalized muscle cell, our viewpoint dives in as first the cell membrane dissolves followed by the sarcoplasmic reticulum to reveal the bundles of thin and thick filaments within a myofibril. Our view then shifts to show the sliding action of contraction, and then a "fly-through" down the longitudinal axis of a sarcomere.
