A lower motor neuron lesion is a lesion which affects nerve fibers traveling from the anterior horn of the spinal cord to the relevant muscle(s) – the lower motor neuron.
One major characteristic used to identify a lower motor neuron lesion is flaccid paralysis – paralysis accompanied by muscle loss. This is in contrast to an upper motor neuron lesion, which often presents with spastic paralysis – paralysis accompanied by severe hypertonia.

Famous quotes containing the word motor:
“We disparage reason.
But all the time it’s what we’re most concerned with.
There’s will as motor and there’s will as brakes.
Reason is, I suppose, the steering gear.”
—Robert Frost (1874–1963)
