How to elicit Palatal reflex?

Ask the subject to open his mouth widely and then touch the mucous membrane covering the palate using a spatula. This produces reflex contraction of the palatal muscles which results in sudden elevation of the palate.
  • Receptors : Touch receptors of the palatal mucosa
  • Afferent limb : Glossopharyngeal nerve and Trigeminal nerve
  • Centre : Vagus nucleus in the medulla
  • Efferent limb : Vagusnerve
  • Effector : Palatal muscle
