Intermediate Taste Buds Quiz

Q1. Where are taste buds located in fungiform papillae?

• Only in the ventral tongue
• Mainly in the superior epithelial surface
• Inside the lingual artery
• Only in deep skeletal muscle

Q2. Where are taste buds concentrated in circumvallate papillae?

• Floor of the mouth
• Keratinized apex only
• Lateral walls facing the trench
• Connective tissue core only

Q3. Where are taste buds associated with foliate papillae primarily found?

• Inside the sublingual gland
• Walls of grooves between foliate folds
• Midline lingual frenulum
• Tip of each filiform papilla

Q4. What is an important role of supporting cells within a taste bud?

• They carry motor axons to the papillae
• They contract the tongue
• They form the bony hyoid
• They support the structure and local environment of receptor cells

Q5. Why must tastants dissolve in oral fluid before they can stimulate taste receptor cells?

• Dissolution converts taste buds into neurons
• It causes papillae to become keratinized
• It opens the lingual artery
• Dissolution allows chemicals to reach receptors at the apical microvilli

Q6. Which glands help flush the trenches surrounding circumvallate papillae?

• Parotid glands
• Meibomian glands
• Ceruminous glands
• Von Ebner glands

Q7. Which cranial nerve carries taste from circumvallate papillae?

• Chorda tympani only
• Lingual nerve alone
• Glossopharyngeal nerve, CN IX
• Hypoglossal nerve

Q8. Which nerve carries taste from the epiglottic region?

• Hypoglossal nerve
• Greater auricular nerve
• External laryngeal nerve only
• Internal laryngeal branch of CN X

Q9. Where are the primary sensory neuron cell bodies for taste fibers carried by the facial nerve?

• Trigeminal ganglion
• Geniculate ganglion
• Otic ganglion
• Ciliary ganglion

Q10. Where do primary gustatory afferents from CN VII, IX, and X terminate centrally?

• Caudate nucleus
• Red nucleus
• Hypoglossal nucleus
• Nucleus of the solitary tract
