For spinal nerves, the general somatic efferent motor neurons have their cell bodies located in the ventral horn of the spinal cord (sometimes also called the anterior horn).Some of your cranial nerves also have motor neurons located in various nuclei of the brainstem.
Several diseases attack the motor neurons that have cell bodies located in the anterior horn of the spinal column namely: amyotropic lateral sclerosis, spinal muscular atrophies, primary lateral sclerosis, and Kennedy's disease (see the linked article for more detail).
