The lingual nerve provides sensation to which structure?

The lingual nerve provides sensation to which structure?

• A. Tongue
• B. Gingiva of maxillary teeth
• C. Palate
• D. Cheek

Answer: (A)

The main concept is that the lingual nerve, a branch of the mandibular division of the trigeminal nerve, provides general sensation to the anterior two-thirds of the tongue. It also supplies the floor of the mouth and the lingual gingiva of the mandible. Among the options, the structure most accurately within this nerve’s sensory domain is the tongue, making it the correct choice. The maxillary gingiva is innervated by branches of the maxillary nerve, the palate by palatine branches, and the cheek by the buccal (long buccal) nerve, not the lingual nerve.
