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