| Here is a Sequence of Basic Muscle Summary Events We Have Covered Up to this Point. Please Learn and Quiz Yourself Below to see if you can put these Events in Correct Order. | ||||||||
| 1. Impulse arrives at neuromuscular junction 2. Acetylcholine (ACh) released and motor end plate depolarizes 3. Impulse travels t-tubules to sarcoplasmic reticulum (SR) 4. Calciums ions (Ca2+) are released 5. Ca2+ binds with troponin 6. Tropomyosin shifts, binding sites available 7. ATPase splits ATP to ADP + Pi + Energy 8. S1 unit binds actin 9. Power Stroke 10. Impulse stops, Ca2+ pumped back into SR 11. Tropomyosin returns over binding sites |

| Here is a Sequence NOT IN CORRECT order. Please Print out and see if you can put in correct order. Please start with the arrival of the impulse at the neuromuscular junction. Check your work with the numbered above. | ||||||||
