The semicircular canals and vestibular sacs contain fluid that moves as the head tilts and stimulates hair receptors
nociceptors
sensory receptors that detect hurtful temperatures, pressures or chemicals
gate-control theory
the spinal cord contains a neurological "gate" that blocks pain signals or allows them to pass on to the brain.
