  2. Tongue - Wikipedia

    en.wikipedia.org/wiki/Tongue

    The tongue's upper surface (dorsum) is covered by taste buds housed in numerous lingual papillae. It is sensitive and kept moist by saliva and is richly supplied with nerves and blood vessels. The tongue also serves as a natural means of cleaning the teeth. [2] A major function of the tongue is to enable speech in humans and vocalization in ...

  3. Frenulum of the tongue - Wikipedia

    en.wikipedia.org/wiki/Frenulum_of_the_tongue

    Ankyloglossia, also known as tongue-tie, is a congenital anomaly characterised by an abnormally short lingual frenulum; when severe, the tip of the tongue cannot be protruded beyond the lower incisor teeth. [6] There are two generalized classifications of ankyloglossia, anterior and posterior tongue-ties.

  4. Lingual papillae - Wikipedia

    en.wikipedia.org/wiki/Lingual_papillae

    The circumvallate papillae get special afferent taste innervation from cranial nerve IX, the glossopharyngeal nerve, even though they are anterior to the sulcus terminalis. The rest of the anterior two-thirds of the tongue gets taste innervation from the chorda tympani of cranial nerve VII, distributed with the lingual nerve of cranial nerve V.

  5. Lingual nerve - Wikipedia

    en.wikipedia.org/wiki/Lingual_nerve

    The lingual nerve supplies general somatic afferent (i.e. general sensory) innervation to the mucous membrane of the anterior two-thirds of the tongue (i.e. body of tongue) (whereas the posterior one-third (i.e. root of tongue) is innervated via the glossopharyngeal nerve (CN IX) [citation needed]), the floor of the oral cavity, and the mandibular/inferior lingual gingiva.

  6. Chorda tympani - Wikipedia

    en.wikipedia.org/wiki/Chorda_tympani

    Injury to the chorda tympani nerve leads to loss or distortion of taste from anterior 2/3 of tongue. [13] However, taste from the posterior 1/3 of tongue (supplied by the glossopharyngeal nerve) remains intact. The chorda tympani appears to exert a particularly strong inhibitory influence on other taste nerves, as well as on pain fibers in the ...

  7. Anterior lingual glands - Wikipedia

    en.wikipedia.org/wiki/Anterior_lingual_glands

    Anterior lingual glands (also called apical glands) are deeply placed seromucous glands that are located near the tip of the tongue on each side of the frenulum linguae.They are found on the under surface of the apex of the tongue, and are covered by a bundle of muscular fibers derived from the styloglossus and longitudinalis inferior.

  8. Hyoid bone - Wikipedia

    en.wikipedia.org/wiki/Hyoid_bone

    The hyoid bone (lingual bone or tongue-bone) (/ ˈ h aɪ ɔɪ d / [2] [3]) is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. At rest, it lies between the base of the mandible and the third cervical vertebra .

  9. Human mouth - Wikipedia

    en.wikipedia.org/wiki/Human_mouth

    The floor is formed by the mylohyoid muscles and is occupied mainly by the anterior two-thirds of the tongue. A mucous membrane – the oral mucosa, lines the sides and under surface of the tongue to the gums, and lines the inner aspect of the jaw . It receives secretions from the submandibular and sublingual salivary glands.
