Question 10

T/F- Lesion to the primary motor cortex or upper motor neuron causes paralysis

Answer 10

True

Question 11

T/F- Lesion to the lower motor neuron in SC, ventral root or nerve does not causes paralysis

Answer 11

False- They do cause paresis/paralysis

Question 12

T/F- Lesion or damage to premotor cortex or other planning areas causes apraxia

Answer 12

True. Apraxia is inability to execute movement despite being able to demonstrate normal muscle function
