  3. What are the intrinsic muscles of the tongue? The intrinsic muscles of the tongue include the superior longitudinal, inferior longitudinal, transverse, and vertical muscles.
  4. What are the extrinsic muscles of the tongue? The extrinsic muscles of the tongue include the genioglossus, hyoglossus, styloglossus, and palatoglossus muscles.
  5. What is the nerve supply to the tongue? The tongue is innervated by the hypoglossal nerve (CN XII) for motor functions and the lingual nerve (a branch of the mandibular nerve, CN V3) for sensory functions.
  6. What is the blood supply to the tongue? The blood supply to the tongue includes branches from the lingual artery (a branch of the external carotid artery) and the dorsal lingual veins.
  7. What is the role of the lingual papillae? Lingual papillae house taste buds and are involved in the perception of taste.
  8. Name the types of lingual papillae. The types of lingual papillae are filiform, fungiform, circumvallate, and foliate papillae.
  9. What is the function of filiform papillae? Filiform papillae provide mechanical friction for food manipulation and contribute to the tongue’s rough texture. Viva Question and Answers Related to Thyroid Glands
  10. Where are fungiform papillae located, and what is their function? Fungiform papillae are located on the anterior two-thirds of the tongue and contain taste buds for the perception of taste.
  11. Describe circumvallate papillae. Circumvallate papillae are large, dome-shaped papillae located in a row at the back of the tongue, containing numerous taste buds.
  12. What is the role of foliate papillae? Foliate papillae house taste buds on the lateral aspects of the posterior tongue.
  13. How does the tongue contribute to speech? The tongue’s movements and positions are crucial for articulating various speech sounds.
  14. What is the gag reflex, and how is the tongue involved? The gag reflex is a protective reflex triggered by touching the soft palate, uvula, or back of the tongue, involving the contraction of the tongue and pharyngeal muscles to prevent choking.
  15. How does the tongue assist in swallowing? The tongue helps in pushing food to the back of the mouth during the oral phase of swallowing, initiating the swallowing reflex.
  16. What is the role of the lingual frenulum? The lingual frenulum anchors the tongue to the floor of the mouth and limits its movement.
  17. What are some common tongue abnormalities? Common tongue abnormalities include geographic tongue, hairy tongue, fissured tongue, and oral thrush. Viva Questions and Answers related to Mouth, Pharynx, and Larynx
  18. How does aging affect the tongue? Aging can lead to changes in taste perception, reduced saliva production, and alterations in tongue mobility.
  19. What are some clinical examinations of the tongue? Clinical examinations of the tongue include assessing its size, shape, color, texture, movements, and presence of any lesions or abnormalities.
  20. How can tongue abnormalities be diagnosed? Tongue abnormalities can be diagnosed through physical examination, imaging studies (such as MRI or CT scan), and biopsy if necessary.
  21. What are the functions of taste buds? Taste buds are specialized sensory organs that detect sweet, sour, salty, bitter, and umami tastes, contributing to the perception of flavors.
  22. How are taste signals transmitted from taste buds to the brain? Taste signals are transmitted via cranial nerves (such as the facial nerve, glossopharyngeal nerve, and vagus nerve) to the brainstem and then relayed to higher brain regions for taste perception.
  23. What is dysgeusia, and how does it relate to the tongue? Dysgeusia is a disorder characterized by altered taste perception, which can be related to tongue abnormalities or dysfunction.
  24. How does tongue posture affect oral health? Proper tongue posture against the palate is important for maintaining dental occlusion, swallowing efficiency, and oral hygiene.
  25. What are some tongue-related conditions that dentists commonly encounter? Dentists commonly encounter conditions such as tongue thrusting, tongue tie (ankyloglossia), oral cancer affecting the tongue, and oral lesions requiring diagnosis and management.
