<prompt> Which of the following does not give sensory supply to the pinna:Auricotemporal NerveGreat Auricular NerveLesser Occipital NerveTympanic branch of Glossopharyngeal Nerve  <response>: D i.e. Tympanic branch of glossopharyngeal nerveTympanic branch of glossopharyngeal IX nerve or Jacobsons nerve supplies the medial inner surface of tympanic membrane. It does not supply pinnaQ.Main nerves supplying the skin of auricle pinna are great auricular nerve c2, CP and auriculo temporal nerve V32 with a small contribution from lesser occipital nerve, C2, auricular branch of vagus X nerve or Arnolds nerve and facial nerve.The great auricular supplies the whole of the cranial medial back surface of auricle C2, with a little overlap from the lesser occipital at the top and the posterior pa of lateral front surface helix, anthelix, and lobule.The auriculo temporal nerve br. of CNV3 supplies the upper pa of lateral surface , skin of auricle anterior to external acoustic meatus, tragus, crus adjacent pa of helix and most of meatal skin.Auricular branch of vagus Arnolds nerve supplies skin on the concavity of concha posterior pa of eminentia , posterior wall floor of meatus and adjoining tympanic membrane.
