Final answer:
Yes, lower motoneuron lesions do present with weakness.
Step-by-step explanation:
Yes, lower motoneuron lesions do present with weakness.
A lesion on the lower motoneuron (LMN) would result in paralysis or partial loss of voluntary muscle control, known as paresis. This paralysis is called flaccid paralysis and refers to a complete or partial loss of muscle tone. Other signs of an LMN lesion include fibrillation, fasciculation, and compromised or lost reflexes resulting from the denervation of the muscle fibers.
