<prompt> Massage and the application of liniments to painful areas in the body relieves pain due toStimulation of endogenous analgesic systemRelease of endorphins by the first order neurons in the brain stemRelease of glutamate and substance P in the spinal cordInhibition by large myelinated afferent fibres  <response>: Massage and liniments application causes a tactile stimulus which is transmitted by Aβ fibers which are large myelinated fibers. This causes stimulation of enkephalinergic inhibitory interneurons through the collaterals, thus inhibiting the pain sensation through the spinothalamic tract.
