  3. Type 2
  4. Unmyelinated Fibers
  5. What are the 3 parts?
  1. a the head of a myosin molecule in the thick filament is not attached to a bonding site on the thin filament; the release of Ca++ causes myosin head to bind ot the thin filament; a ratcheting acting of the heads pulls the thin filament toward the center of the sacromere; the myosin head detaches and is about to bind to the next site on thin filament
