Muscular System
Across
- 3. an oxygen-storing, pigmented protein in muscle cells; found in abundance in red muscles
- 6. attachment of a muscle tendon to a moveable bone or the end opposite the origin
- 7. minimal strength required to cause a contraction
- 10. point of contact between a motor neuron and a skeletal muscle cell
- 12. time between application of a stimulus and the beginning of a response in a muscle fiber
- 13. thick protein filaments in muscle tissue
- 14. muscle that assists a prime mover in performing its primary action
Down
- 1. alternate dark and light bands found on skeletal and cardiac muscle; dark, thick bands are myosin and light, thin bands are actin
- 2. a muscle that resists the action of the prime mover
- 4. attachment of a muscle that remains relatively fixed during muscular contraction
- 5. thin protein filaments in muscle tissue
- 8. neurons that carry outgoing information from the brain and spinal cord to the muscles and glands
- 9. muscle with the major responsibility for a certain movement
- 11. the process of wave-like muscle contractions of the digestive system (smooth muscle) that moves food along
