Why does nociceptive pain, resulting from a deep tissue injury, often present as a broader, less precisely localized sensation compared to acute cutaneous pain from a paper cut?

💡 Explanation

Deep tissue pain is diffuse because nociceptive signals converge onto widely branching secondary neurons within the spinal cord dorsal horn via divergent neuronal pathways, therefore the brain struggles to pinpoint the exact source, rather than the sharper representation of cutaneous pain that has more direct mapping.
