What three body systems are affected by Huntington's disease, which negatively impacts human movement?

• A. Nervous, Muscular, and Skeletal
• B. Digestive, Endocrine, and Integumentary
• C. Circulatory, Immune, and Respiratory
• D. Skeletal, Nervous, and Circulatory

Answer: (A)

Huntington's disease primarily affects the nervous system due to the progressive degeneration of nerve cells in the brain, particularly in areas that control movement, mood, and cognitive functions. This neurological impact leads to movement disorders commonly associated with the disease, including chorea, which is characterized by rapid, unintentional movements. The muscular system is also affected because the nervous system's degradation disrupts the signals that lead to coordinated muscle movement. As a result, individuals with Huntington's disease may experience difficulties with muscle control, leading to problems with voluntary movements. While the skeletal system may experience secondary effects due to the changes in movement and muscle control, it is not primarily impacted by Huntington's disease in the same way as the nervous and muscular systems. Therefore, the combination of the nervous and muscular systems, alongside the indirect influence on the skeletal system due to movement challenges, makes this answer correct in the context of how Huntington's disease impacts human movement.
