Question 33
What occurs when the sarcomere length of skeletal muscle is reduced beyond the length w optimum force is developed?
1. The amount of calcium released by the sarcoplasmic reticulum is reduced as length increases.
2. The thin filaments are pulled away from one another, thereby reducing their ability to interact with
3. The thick filaments are pulled away from one another, thereby reducing their ability to interact with
4. The thick filaments overlap one another, thereby reducing their ability to interact with actin.
5. The thin filaments overlap one another with myosin bumping into the Z-line, thereby causing the for generated by cross bridges to be exerted on the sarcomere itself rather than transmitted to the end muscle fiber.
Question 34

1. Vasodilation; active
2. Vasodilation; reactive
3. Vasoconstriction : active
4. Vasoconstriction: reactive
