Question

Difference between upper motor neuron and lower motor neuron in neurology

Answer 1

upper motor neuron:

a motor neuron that originates from the motor region of the cerebral cortex or from the brain stem.

located near the central nervous system.

transmit nerve impulses from the brain to the synapses of the lower motor neuron.

cell bodies are bigger located in the brain cortex.

has six pathways.

lower motor neuron:

transmits nerve impulses from upper motor neuron to the effector muscles.

located near muscles.

form synapses with muscles.

found in brain stem and spinal cord.

include cranial and spinal nerves.

hope it helps:

thanks

Answer 2

Upper motor neurons originate in the motor region of the brain stem. ... On the other hand, lower motor neurons receive impulses from the upper motor neurons and connect the spinal cord and brain stem to the muscle fibers. They are the cranial and spinal nerves

he fibers of the upper motor neurons project out of the precentral gyrus ending in the brainstem, where they will decussate (intersect) within the lower medulla oblongata to form the lateral corticospinal tract on each side of the spinal cord.
