Across
  1. 3. a muscle that works in opposition to the prime mover (agonist) during a movement
  2. 5. a sudden, involuntary contraction or tightening of a muscle that causes pain and discomfort
  3. 6. cardiac muscle tissue
  4. 7. the process in which a muscle fiber generates tension and shortens or tightens in response to a signal from the nervous system
  5. 9. refers to the ability of muscle fibers to shorten and generate force when stimulated
  6. 10. the alternating light and dark bands visible in certain types of muscle tissue, specifically skeletal muscle and cardiac muscle, when viewed under a microscope
  7. 11. fiber a single, elongated cell of a muscle tissue that is specialized for contraction
  8. 12. refers to the ability of muscle cells (fibers) to respond to stimuli, typically from the nervous system, by generating an electrical impulse (action potential) that triggers muscle contraction; quick to react
  9. 15. the ability to move or control objects or parts of the body with precision; fine motor skills
  10. 17. the state of slight tension in muscles that helps maintain posture and readiness for action
  11. 18. the loss of the ability to move or control muscles, typically due to damage to the nervous system
  12. 20. muscles that function automatically without conscious control
Down
  1. 1. muscles that are attached to bones and are responsible for body movements
  2. 2. the fixed attachment point where a muscle is connected to a bone or other structure that does not move during muscle contraction
  3. 3. the primary muscle responsible for producing a specific movement during a particular action
  4. 4. the ability of muscles to produce movement that enables an organism to move from one place to another; gross motor movements
  5. 8. the point where a muscle is attached to a bone or other structure that moves when the muscle contracts
  6. 13. muscle Found exclusively in the heart, responsible for pumping blood.
  7. 14. muscles that are under conscious control, meaning you can decide when and how to move them
  8. 16. tough, flexible bands of fibrous connective tissue that connect muscles to bones
  9. 19. muscle Found in the walls of internal organs like the stomach, intestines, and blood vessels.
