Dimples are especially common in the face, because the muscles pull the skin on the face around, instead of just pulling around bones. The face also has bits of body fat, which cause the dimples to be more visible. Most cheek dimples are the result of a shortened muscle, zygomaticus major, pulling on the skin. There are dimples in the chin and the elbows, as well. At rest, it's not noticeable, but as the muscles around it pull into a smile, its shortness creates divots in the face.
Muscular dystrophy (MD) is a group of muscle diseases that weaken the musculoskeletal system and hamper locomotion. Muscular dystrophies are characterized by progressive skeletal muscle weakness, defects in muscle proteins, and the death of muscle cells and tissue.pecific muscle groups are affected by different types of muscular dystrophy. Often, there is a loss of muscle mass (wasting), which may be hard to see because some types of muscular dystrophy cause a buildup of fat and connective tissue that makes the muscle appear larger.
