Characteristics that distinguish upper motor neuron lesions from lower motoneuron lesions is (are) (assume the lesions are total):
A. reflex movements are possible with upper but not lower motoneuron lesions.
B. fibrillation potentials in the EMG are present in upper but not lower motoneuron lesions.
C. there is eventual severe muscle degeneration with wasting of muscle tissue with upper motoneuron lesions.
D. all of the above
E. A and C only
