Which of the following statements is correct? answer rebound phenomena refers to the inability to grab a rebound above the rim past pointing is a cardinal sign of corticospinal damage intention tremor is seen following lesions of the substantia nigra resting tremor is seen following lesions of the cerebellum atrophy is not a sign of cerebellar disease 18. Which of the following statements is correct? answer hypotonia could never result from defects in the gamma efferent system spasticity is associated with lesions of the lateral cerebellum both cerebral cortex and cerebellar deficits involve the ipsilateral side of the body weakness is a cardinal sign of cerebellar disease ataxia is a cardinal sign of cerebellar disease 19. Which of the following statements is correct? answer the fastigial nucleus projects to the red nucleus the presence of nystagmus suggests damage to the corticospinal tract the inferior olive receives input from the contralateral spinal cord the interpositus nucleus projects to the vestibular nuclei via the inferior cerebellar peduncle nystagmus is a sign of lower motor neuron disease 20. Which of the following statements is correct? answer a lesion of the right side of the flocculonodular lobe will result in left nystagmus a lesion of the right side of the flocculonodular lobe will result in staggering to the right a lesion of the right fastigial nucleus will result in staggering to the left a lesion of the right fastigial nucleus will result in right nystagmus a lesion of the right fastigial nucleus and the right vestibular nuclei will (in different cases) result in nystagmus of the same direction 21.
