How do muscles work?

1.	How do muscles work?
Answer» There are two types of muscle: striated and smooth. The formerhave regular stripes, or striations, when observed under a microscope. These striations are due to the arrangement of muscle fibers, which form parallel lines. The muscles that move our body parts are called skeletal muscles, and they area type of striated muscle. We can actively control these with our brain. Another type of striated muscle are those that keep our hearts pumping, which we are unable toactively control. Specific molecules within the muscle fibers allow striated muscles to contract rapidly, allowing us to move. The main players in this intricate process are molecules called actin and myosin.
