Across
  1. 2. Stabilizes the sarcolemma by attaching the actin cytoskeleton to the extracellular matrix. Helps transmit the tension generated by the sarcomeres to the tendons.
  2. 4. Protein of the thin filament covering actin’s active sites between contractions.
  3. 6. Protein of the thin filament to which calcium binds.
  4. 7. Elastic protein providing structure, flexibility, and stability to the sarcomere, keeps the components of sarcomeres in place as muscles contract and relax.
Down
  1. 1. Forms the M line
  2. 3. Part of the thin filaments of myofibrils, has an active site of attachment for myosin.
  3. 5. Makes up the thick filament, forms cross-bridges with actin.
