Across
  1. 7. Junctions between cardiac muscle cells allowing synchronized contractions.
  2. 8. Property of being stretched without damage.
  3. 9. Specialized cells initiating rhythmic contractions (e.g., in heart or gut).
  4. 13. Long, cylindrical cells composing skeletal and cardiac muscle.
  5. 14. Calcium-binding protein in smooth muscle, activating contraction.
  6. 18. Smooth muscle contracting as a single unit (e.g., in intestines).
  7. 20. Involuntary striated muscle found in the heart, responsible for pumping blood.
  8. 22. Muscle cells capable of contraction.
  9. 23. Enzyme phosphorylating myosin in smooth muscle contraction.
  10. 24. Capacity to respond to electrical or chemical signals.
Down
  1. 1. Voluntary striated muscle attached to bones, enabling movement.
  2. 2. Ability to propagate electrical impulses along the cell membrane.
  3. 3. Wave-like smooth muscle contractions moving substances through tubes (e.g., digestive tract).
  4. 4. Anchor points for thin filaments in smooth muscle cells.
  5. 5. Muscle's ability to adapt structurally/functionally to demands.
  6. 6. Synonymous with unitary smooth muscle.
  7. 10. Striped appearance in skeletal/cardiac muscle due to sarcomere arrangement.
  8. 11. Involuntary non-striated muscle in visceral organs, controlling slow contractions (e.g., peristalsis).
  9. 12. Ability of some muscles (e.g., heart) to contract without neural input.
  10. 15. Exercise increasing muscle strength/size via weight-bearing activity.
  11. 16. Smooth muscle fibers contracting independently (e.g., in iris).
  12. 17. Exercise improving aerobic capacity and fatigue resistance.
  13. 19. Circular smooth muscles regulating passage through openings (e.g., esophageal sphincter).
  14. 21. Ability of muscle to shorten forcibly when stimulated.
