Q
LMN lesion (Peripheral motor neuron lesion)
Signs:
A
LMN lesion (Peripheral motor neuron lesion)
- ↓tone, flaccid paralysis, hyporeflexia, *NO pyramidal signs
- atrophy (nutritional stimulus goes through peripheral nerve)
*Preferential innervation of pyramidal tracts: wrist extensor, forearm supinator, foot extensor
- if there’s a pyramidal tract lesion those movements will be weak!
