Intermediate Taste Buds Quiz

Q1. Where are taste buds located in fungiform papillae?

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

Q2. Where are taste buds concentrated in circumvallate papillae?

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

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

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

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

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

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

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

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

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

Q7. Which cranial nerve carries taste from circumvallate papillae?

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

Q8. Which nerve carries taste from the epiglottic region?

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

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

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

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

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