Question

lower motor neurons
where are the cell bodies of lower motor neurons (lmn) located?
anterior horn of spinal gray matter
motor area of the cerebral cortex
dorsal horn of spinal gray matter
brainstem

Explanation:

Lower motor neurons (LMN) are neurons that directly innervate skeletal muscles. Their cell bodies are located in the anterior (ventral) horn of the spinal gray matter. The motor area of the cerebral cortex contains upper motor neurons. The dorsal horn of the spinal gray matter is mainly involved in sensory processing. While some motor neurons have cell bodies in the brainstem (such as cranial nerve motor nuclei), the most typical location for the cell bodies of LMNs (for the spinal nerves innervating trunk and limb muscles) is the anterior horn of spinal gray matter.

Answer:

Anterior horn of spinal gray matter
