Which structure contains motor neuron cell bodies?

Explanation:
Motor neuron cell bodies reside in the gray matter of the spinal cord, specifically in the ventral (anterior) horn. These neurons send their axons out through the ventral root to innervate skeletal muscles. The dorsal root contains sensory fibers, with the cell bodies in the dorsal root ganglion, and white matter is made up of myelinated axons, not neuron bodies. So the anterior horn is the location of motor neuron cell bodies.
