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