**Question:** Which of the following are correct regarding processes that are involved in the latent period of a muscle twitch? (choose all that apply)- □ Acetylcholine binds to nicotinic receptors on the motor-end-plate- □ Myosin binds with Actin forming the "cross-bridge"- □ Power-Stroke Cycling is occurring- □ Action potential travels down T-Tubules- □ Calcium is released from Terminal Cisternae and binds to Troponin**Explanation:**This question involves the sequence of events occurring during the latent period of a muscle twitch. The latent period is the time between the initiation of a stimulus and the beginning of a muscle contraction.

Muscle fibers consist of a single muscle cell. They help control the body's internal energy. When they are assembled, they can facilitate the smooth movement of your legs and muscles. There are several types of fiberglass, each with different characteristics.

Slightly flexed muscle fibers resist fatigue, and focus on continuous, slow movement and back control. They contain a lot of mitochondria and myoglobin, and they are naturally aerobic compared to fast fibers. Slow-twitch fibers are also sometimes called type I or red fibers due to blood supply.
