Nerve and Spinal Cord
Motor neuron cell bodies are in the ventral horn of the spinal cord. The axons of these neurons travel outward through the ventral root.

| A sensory neuron has its cell body in the dorsal root ganglion. One end of the neuron travels out to the periphery throught the peripheral nerve (dorsal and ventral ramus), while the other end travels into the spinal cord through the dorsal root. Inside the spinal cord, sensory neurons carrying pain signals (nociceptors) typically have a "synapse" just past the dorsal root entry zone where they pass their electrical signal on to another neuron. Other sensory neurons may continue up to the base of the brain before arriving at their first synapse.
