2. ___________ is the neurotransmitter used to pass an action potential from nerve to muscle.

3. Regardless of training history, the soleus muscle consists of mostly type ____ fibers.

4. The theory that states that muscle fibers contract when thick and thin filaments slide past each other is called the _________________ theory.

5. Type _____ fibers are typically engaged during short, higher-intensity exercise that involves some degree of endurance.

6. Type ______ fibers are not very easily stimulated by the nervous system, meaning that they typically are not engaged until all other fiber types have been stimulated first.
