Which of the following is characterized by degeneration of muscle and weakness?

• A. Muscular Dystrophy
• B. Cerebral Palsy
• C. Spinal Muscular Atrophy
• D. Multiple Sclerosis

Answer: (A)

Muscular Dystrophy is a group of inherited disorders characterized by progressive degeneration of muscle fibers. This condition leads to muscle weakness and a gradual loss of muscle mass and function. It typically manifests in childhood, though some forms can appear in adulthood. The degeneration is primarily due to genetic mutations that affect proteins needed for healthy muscle structure and function.

When considering other conditions, Cerebral Palsy primarily affects movement and posture due to brain injury or maldevelopment, not muscle degeneration itself. Spinal Muscular Atrophy also involves muscle weakness due to nerve degeneration, but it is distinct from Muscular Dystrophy in terms of its underlying cause and implications. Multiple Sclerosis is an autoimmune disease affecting the central nervous system, leading to a range of neurological symptoms, but again, it does not specifically involve the primary degeneration of muscle tissue itself. Thus, Muscular Dystrophy stands out as the condition most directly associated with the defined characteristics of muscle degeneration and weakness.
