Intermediate Papillae Quiz

Q1. What type of epithelium covers lingual papillae?

• Pseudostratified ciliated columnar epithelium
• Simple cuboidal epithelium
• Transitional epithelium
• Stratified squamous epithelium

Q2. Why are filiform papillae well suited to a mechanical function?

• They contain intrinsic skeletal muscle within each papilla
• They contain large cartilage cores
• Their pointed, keratinized surfaces increase friction
• They secrete saliva through central ducts

Q3. Where are taste buds especially abundant in circumvallate papillae?

• Ventral tongue surface
• Deep within the skeletal muscle core
• Keratinized tips only
• Lateral walls facing the surrounding trench

Q4. Which glands empty into the trenches surrounding circumvallate papillae?

• Von Ebner glands
• Ceruminous glands
• Parotid glands
• Sublingual glands

Q5. What is an important function of von Ebner gland secretion?

• Contracting intrinsic tongue muscles
• Producing mucus for the nasal cavity
• Keratinizing filiform papillae
• Flushing tastants from the circumvallate trenches

Q6. Which cranial nerve carries taste from circumvallate papillae?

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

Q7. Which nerve carries taste from most fungiform papillae?

• Glossopharyngeal nerve only
• Chorda tympani of CN VII
• Hypoglossal nerve
• Accessory nerve

Q8. How are taste buds arranged in foliate papillae?

• Only at the keratinized apex of each fold
• In the walls of grooves between the folds
• Inside the lingual artery
• Within the intrinsic tongue muscles

Q9. How do foliate papillae typically change with age?

• They are absent at birth and appear only in old age
• They become the dominant papillae in adults
• They are more prominent in children and often less distinct in adults
• They transform into circumvallate papillae

Q10. Which feature best distinguishes a taste bud from the surrounding stratified squamous epithelium?

• An ovoid sensory cell cluster opening through a taste pore
• A skeletal muscle fascicle
• A keratinized connective tissue spine
• A mucous acinus with no surface opening
