What is the difference between muscle dystrophy and muscle atrophy?

Answer 1

Myasthenia gravis: autoimmune to the ACh receptors at end plate (pathway >>> no muscle contraction)

Muscular Dystrophy: genetic (X-linked) defect in dystrophin (pathway >>> myosin-actin crossbridge doesn't form > no muscle contraction)

Answer 2

The difference between muscle atrophy and dystophy is that the atrophy is a wasting away of muscle due to disease or poor nutrition. Muscle dystrophy is degeneraion of muscles or any organs in the body caused by a disease process, or it can also be caused by malnourishment.
