Que son los filamentos de miosina?

Myosin filaments also called thick filaments are key components of muscle and non-muscle cells. In striated muscle, they overlap with thin acting containing filaments in an orderly array, making a repeating pattern of sarcomeres, the basic units of contraction

Explanation:

between the two muscle layers is the myenteric or auerbach's plexus, which controls peristalsis. in the colon, the muscularis externa is much thicker because the feces are large and heavy, requiring more force to push along. the stomach has a third layer of muscularis externa: the inner oblique layer.
