Editing Referred pain (section)

===Axon-reflex===
Axon reflex suggests that the afferent fiber is bifurcated before connecting to the [[posterior horn of spinal cord|dorsal horn]]. Bifurcated fibers do exist in muscle, skin, and intervertebral discs. Yet these particular neurons are rare and are not representative of the whole body. Axon-Reflex also does not explain the time delay before the appearance of referred pain, threshold differences for stimulating local and referred pain, and somatosensory sensibility changes in the area of referred pain.<ref name=ArendtNeilsen/>
