Which disorder leads to the progressive degeneration of voluntary muscle control?

Muscular dystrophy is a group of inherited disorders characterized by progressive degeneration and weakness of the voluntary muscles over time. This condition is caused by mutations in the genes responsible for muscle function, leading to the gradual loss of muscle fibers and strength. As the muscles weaken, individuals may experience difficulties with movements such as walking, running, and performing everyday activities. The progression varies depending on the specific type of muscular dystrophy, but it typically involves an overall decline in muscle control and function.

Other disorders mentioned in the options affect muscles and the nervous system but operate differently. Cerebral palsy is primarily a movement disorder caused by brain damage, affecting muscle coordination rather than leading to direct degeneration of muscle. Multiple sclerosis is an autoimmune condition that impacts the central nervous system, leading to varying degrees of muscle control disturbances, but it does not cause the progressive muscle degeneration like muscular dystrophy. Guillain-Barré syndrome is an acute condition where the immune system attacks the peripheral nervous system, leading to rapid-onset muscle weakness but is typically temporary rather than progressive like muscular dystrophy. Thus, muscular dystrophy specifically aligns with the description of progressive degeneration of voluntary muscle control.
