ankistrugglesI thought it was ALS too (and I think it still could be?) but my thought process was that a lower motor neuron lesion would be the more specific answer.+12019-05-21T22:10:52Z
sattankiYeah makes sense, just threw me off cause ALS is both lower and upper motor neuron problems. Corticospinal tract would have been a better answer if they described more upper motor neuron symptoms, but as you said, they only describe lower motor neuron symptoms. Thanks!+12019-05-21T22:11:44Z
mousieAgree I thought ALS too but eliminated Peripheral nerves and LMN because I guess I thought they were the same thing ....??? Am I way off here or could someone maybe explain how they are different?
baconpiesperipheral nerves would include motor & sensory, whereas LMN would be just motor+92019-06-06T23:05:58Z
seagullAlso, a LMN damage wouldn't include both hand and LE unless it was somehow diffuse as in Guil-barre syndrome. It would likely be specific to part of a body. right???+2019-06-07T02:25:30Z
charcot_bouchardNo. if it was a peri nerve it would be limited to a particular muscle or muscles. but since its lower motor neuron it is affecting more diffusely. Like u need to take down only few Lumbo sacral neuron to get lower extremity weakness. but if it was sciatic or CFN (peri nerve) it would be specific & symptom include Sensory.+2019-06-26T05:49:42Z
vulcaniaI think it's ALS too. The correct answer choice here seems more based on specific wording:
the answer choice "Corticospinal tract in the spinal cord" wouldn't explain the tongue symptoms, since tongue motor innervation doesn't involve the corticospinal tract or the spinal cord (it's corticobulbar tract). This is a situation of "BEST answer choice," not "only correct answer choice."+2020-02-11T19:05:20Z
