Fast pain differs from slow pain in a- being transmitted in the dorsal column pathwayb- evoking a depressor autonomic reactionc- having a sharp qualityd- arising from encapsulated pain receptors

Question 191 ptsIf a sudden painful stimulus is applied to one of the limbs, which of the following is LEAST likely to follow:Group of answer choicesa rapid flexing of the affected limba rapid extension of the contralateral limbactivation of A-delta nociceptor axons which trigger reflex responsesa rapid flexing of the contralateral limbactivation of C-fibre nociceptors which give rise to a painful sensation that outlasts the stimulus

Describe the structures that act as pain receptors.Multiple ChoiceEncapsulated nerve endingsSpecialized receptors within complex structuresFree nerve endings

In the neurons that are responsible for our sensation of pain, some are myelinated and some are unmyelinated.  The main consequence of this difference is:Group of answer choicesThe myelinated fibres required more intense stimuli and unmyelinated fibres.Pain signals travel rapidly down the unmyelinated fibre and slower down the myelinated fibres.The sense of pain from myelinated fibres is more intense than unmyelinated fibres.Unmyelinated fibres respond with graded potentials, whereas unmyelinated fibres respond with action potentials.Pain signals travel rapidly down the myelinated fibre and slower down the unmyelinated fibres.

Stimulation of pain receptors in an internal organ that is also felt in another area of the body is called pain.

Receptors in the skin are sensitive to pain, pressure, touch and what else?
