<prompt> The highest degree of pain localization comes from which of the following?Simultaneous stimulation of free nerve endings and tactile fibersStimulation of free nerve endings by bradykininNerve fibers traveling to the thalamus by way of the paleospinothalamic tractStimulation of d-type A fibers  <response>: In general, the sensation of pain is poorly localized. However, when a tactile receptor and a pain receptor are stimulated simultaneously, the pain sensation is localized with greater accuracy.
