Answer

Answer

Somatosensory innervation is provided by the maxillary (V2) and mandibular (V3) branches of the trigeminal nerve and the glossopharyngeal nerve (IX).

The V2 branch supplies the following:

  • Hard and soft palate

  • Mucosa of the maxillary vestibule

  • Upper lip

  • Maxillary teeth

  • Maxillary periodontal ligaments

  • Maxillary gingiva

The V3 branch supplies the following:

  • Buccal mucosa

  • Anterior two thirds of the tongue (lingual branch)

  • Mandibular teeth

  • Mandibular periodontal ligaments

  • Mandibular gingiva

  • Anterior mandibular vestibule

  • Lower lip

The glossopharyngeal nerve innervates the following:

  • Posterior third of the tongue

  • Posterior wall of the pharynx
