What trend do you notice between force generation capability of a muscle and its cross-sectional area? If a muscle has a large cross-sectional area, then its force-producing potential is?

What is the sliding filament theory? How do components of the sarcomere change during a muscle contraction?

In the process of muscle contraction, which of the following steps immediately comes after the propagation of an action potential down the t-tubules of a myofiber?   sliding of tropomyosin causing exposure of actin   binding of myosin head to actin's active site   release of calcium from the terminal cisternae   binding of acetylcholine to its receptor   influx of sodium at the sarcolemma

What are some examples of movement created by the contraction of sarcomeres of the muscle cells?
