Muscle Review
Across
- 6. made of the protein actin; also contains troponin and tropomyosin
- 10. pump blood
- 12. a chemical that an axon secretes at a synapse (released at the junction)
- 14. made of the protein myosin
- 16. joint between carpal and metacarpal of the thumb
- 17. cytoplasm of the muscle cell
- 18. on the muscle fiber is where the neuron connects functionally
- 20. controls tropomyosin, in the thin filament (gatekeeper)
- 21. blood pressure, control of blood, move food in the digestive system
- 24. between metacarpals and phalanges
- 25. between atlas and axis
- 26. movement of the body when by the nervous system
- 27. elbow; flexion and extension
- 28. between carpals and tarsals
- 29. functional connection between a neuron and another cell
Down
- 1. cell membrane of a muscle fiber
- 2. These are the functional unit of muscle contraction
- 3. limited movement
- 4. no movement
- 5. contains myofilaments- thick and thin filaments
- 7. Light bands made up of actin filaments (thin)
- 8. a network of membranous channels that holds calcium(Ca).
- 9. a long cylinder muscle cell
- 11. A bundle of cells and perimysium wraps around it.
- 13. moves freely
- 15. dark bands made up of overlapping thick and thin filaments
- 19. blocks myosin-binding sites (gate)
- 22. shoulder and hip
- 23. consist of alternating light and dark bands
