← Human Body & HealthA construction worker wearing vibration-dampening gloves operates a jackhammer. Despite the gloves, prolonged exposure leads to 'hand-arm vibration syndrome' (HAVS). Why does this occur, even with vibration damping?
A)Damping shifts resonant bone frequencies
B)Glove material induces phantom sensations
C)Blood vessel constriction is fully prevented
D)Mechanoreceptor fatigue alters sensory encoding✓
💡 Explanation
Mechanoreceptor fatigue explains the syndrome, because prolonged vibration overwhelms sensory neurons, altering their encoding of touch and position; therefore, sensory perception degrades even with damping, rather than resonant frequency shifts or direct vascular effects alone.
