Intermediate Uvula Quiz

Q1. From which part of the palatal framework does musculus uvulae arise?

• Thyroid cartilage and cricoid cartilage
• Posterior nasal spine and palatine aponeurosis
• Styloid process and hyoid bone
• Mental protuberance and mandible

Q2. How does musculus uvulae assist velopharyngeal closure?

• It retracts the mandible
• It opens the laryngeal inlet
• It thickens the central soft palate during closure
• It depresses the hard palate

Q3. Which plexus carries motor fibers to musculus uvulae?

• Cervical sympathetic plexus only
• Brachial plexus
• Lumbar plexus
• Pharyngeal plexus

Q4. Which trigeminal division contributes general sensory innervation to the soft palate and uvular region?

• Motor root of the facial nerve
• Ophthalmic division, V1
• Mandibular division, V3 only
• Maxillary division, V2

Q5. Which nerves carry sensory fibers from the soft palate near the uvula?

• Mental nerves
• Greater occipital nerves
• Long thoracic nerves
• Lesser palatine nerves

Q6. Which arterial branch of the facial artery contributes to the vascular supply of the soft palate and uvular region?

• Central retinal artery
• Ascending palatine artery
• Anterior cerebral artery
• Inferior alveolar artery

Q7. Which branch of the maxillary artery contributes to the blood supply of the soft palate near the uvula?

• Lesser palatine arteries
• Inferior alveolar artery only
• Deep temporal arteries only
• Middle meningeal artery only

Q8. What is the relationship of the uvula to the palatoglossal and palatopharyngeal arches?

• It lies inside the palatine tonsil
• It lies in the midline between the paired palatal arches
• It forms the muscular core of both arches
• It passes through the mandibular foramen

Q9. What happens to the uvula during normal elevation of the soft palate?

• It descends into the esophagus
• It rotates the mandible
• It enters the auditory tube
• It elevates with the soft palate

Q10. Which function is most closely associated with the uvula as part of the soft palate?

• Contribution to velopharyngeal closure
• Drainage of the parotid gland
• Abduction of the vocal folds
• Generation of mandibular bite force
