Correct Answer � C
Explanation
|
|
– Chronic alcohol use damages the anterior lobe of the cerebellum.
– This region coordinates lower limb movements & posture.
– Damage here → wide-based gait (ataxia) & possibly nystagmus.
Incorrect Options:
– Flocculonodular: Regulates balance & eye movements; not typical in alcohol damage.
– Dentate: Involves voluntary movement; damage causes dysmetria, not ataxia.
– Vermis: Controls axial muscles; not typically affected in alcohol damage.
