LMN vs UMN: pg 32 Flashcards
1
Q
Neurons that synapse on skeletal muscle? LMN or UMN?
A
LMN
2
Q
Neurons that synapses on or near LMN? LMN or UMN?
A
UMN
3
Q
If a LMN were cut what would happen to the muscle strength?
A
Muscle weakness (paresis) or flaccid paralysis
4
Q
If a UMN were cut what would happen to the muscle strength?
A
Muscle weakness or spastic paralysis
5
Q
If the LMN were cut would there be a change in response of muscle to electrical stimulation?
A
EMG: Fibrillation potentials are present
6
Q
If the UMN were cut would there be a change in response of muscle to electrical stimulation?
A
No change in response of muscle to electrical stimulation (muscle is still innervated)
