Which condition is characterized by a lack of voluntary muscle coordination?

• A. Alopecia
• B. Pruritus
• C. Otitis
• D. Ataxia

Answer: (D)

Ataxia means a lack of voluntary muscle coordination. It shows up when the brain’s coordination of movements is off, leading to an unsteady gait, wide-based stance, and clumsy or poorly timed limb movements. Animals with ataxia may stumble, have trouble placing their paws accurately, or show tremors when they try to reach for or move objects. The core issue is integration and timing of movement signals, usually linked to cerebellar dysfunction or its pathways, rather than a problem of strength. The other options describe hair loss, itching, or ear infection—conditions affecting skin/hair or the ears, not the coordination of voluntary muscles.
