Question

Compare and contrast the upper and lower motor neurons
with respect to their cell body origin, what structure(s) they
project to, and whether they are excitatory or inhibitory

Expert Solution
Step 1

Motor neurons are the neurons that carry the nerve impulse from the spinal cord to the effector organ. The somatic neural system originates from the Central Nervous System (CNS) and they carry sensory information to and fro between the muscles and the CNS. The somatic motor pathways have two sets of motor neurons: the upper motor neurons and the lower motor neurons.
