WebOct 22, 2014 · The 2 types of myofilaments are: thin filaments: made of the protein actin, and thick filaments: made of the protein myosin. Myofilaments are arranged to form repeating units termed sarcomeres. During a contraction, myosin heads interact with actin filaments to form cross-bridges. The myosin head pivots, producing motion. This motion … WebThick filaments are composed of myosin, ... The molecular mechanism whereby myosin and acting myofilaments slide over each other is termed the cross-bridge cycle. During muscle contraction, the heads of myosin myofilaments quickly bind and release in a ratcheting fashion, pulling themselves along the actin myofilament.
