Final answer:
The dorsal column-medial lemniscus pathway consists of three neurons.
Step-by-step explanation:
The dorsal column-medial lemniscus pathway consists of three neurons. The first neuron is located in the dorsal root ganglion and enters the dorsal column white matter in the spinal cord. The second neuron is found in the nuclei of the medulla and the axons from the dorsal column terminate in these nuclei. The third and final neuron projects its axons to the postcentral gyrus of the cerebral cortex, where somatosensory stimuli are processed and perceived.
