Question

What is one primary difference between an upper motor neuron and a lower motor neuron?

1. An upper motor neuron exits the spinal cord
2. All upper motor neurons are closer to the brain
3. An upper motor neuron is covered in myelin
4. An upper motor neuron does not exit the spinal cord

Answer 1

Answer ; An upper motor neuron does not exit the spinal cord.

Reason ; One of the major difference between these two two types of neuron is that location where that the neuron present. The activity of the upper motor neuron is only occurs in the central part of the nervous system, that is within the brain and the spinal cord, it doesn't cross out from the spinal cord, but the lower motor neuron will do. Therefore the above mentioned statement would be the primary difference between these two neurons.
