For the contraction of the sarcomere to occur, calcium ions (Ca²⁺) must be present. When a muscle cell is stimulated, calcium is released from the sarcoplasmic reticulum, binding to troponin on the actin filaments. This interaction causes a change in the conformation of tropomyosin, exposing binding sites for myosin, allowing the myosin heads to attach and pull the actin filaments, resulting in contraction.

The correct order of skeletal muscle structures from largest to smallest is: 1. fascicles, 2. muscle cell (or muscle fiber), 3. myofibril, 4. sarcomere, and 5. myofilament. Fascicles are bundles of muscle fibers, which are the individual muscle cells. Myofibrils are found within muscle cells, composed of repeating units called sarcomeres, which contain the myofilaments responsible for muscle contraction.
