The discriminative component of this phenomenon is carried to the pars interpolaris and pars caudalis from the face by the spinal trigeminal tract.
The discriminative component of this phenomenon is carried to the pars interpolaris and pars caudalis from the face by the spinal trigeminal tract. Ronald Melzack and Patrick Wall gave a "gate theory" of this that implicates modulation by low-threshold mechano-receptors on the dorso-lateral tract of Lissauer which runs between neighboring spinal segments. The "referred" type of this is the cutaneous manifestation of a visceral cause, which is normally carried up by the central gray, dorsal septum, midline column, medial lemniscus system involved in mechano-sensation. The A-delta fibers and polymodal C fibers carry the "acute" phase of this and ►its "dull" phase, respectively. Inhibition of COX synthesis of prostaglandins by NSAIDs analgesically relieves, FTP, this sensation of tissue injury, which leads to the feeling of being hurt.
