Q:l upperl motorl neurons

Answer:

locatedl completelyl withinl CNS diseasesl (cerebrovascularl accident,l cerebrall palsy,l multiplel sclerosis,l etc.)

Q:l lowerl motorl neurons

Answer:

finall contactl withl muscles inl anteriorl grayl columnl ofl spinall cord

movementl mustl bel translatedl intol actionl byl these:

-craniall nervesl andl spinall nervesl ofl PNS diseasesl (spinall cordl lesions,l poliomyelitis,l amytrophicl laterall sclerosis)
