Final answer:
Cerebellar ataxia is characterized by uncoordinated muscle movements, while sensory ataxia is related to problems in sensory perception. The former is caused by damage to the cerebellum, while the latter is caused by damage to sensory nerves.
Step-by-step explanation:
Ataxia is a movement disorder that can occur due to cerebellar damage or sensory deficits. Cerebellar ataxia is characterized by uncoordinated muscle movements, while sensory ataxia is related to problems in sensory perception. In cerebellar ataxia, the issue arises from damage to the cerebellum, while sensory ataxia is caused by damage to sensory nerves.
