Intermediate Thyroid Cartilage Quiz

Q1. What surface ridge is present on the lateral surface of each thyroid lamina?

• Oblique line
• Pectineal line
• Superior temporal line
• Mylohyoid line

Q2. Which infrahyoid muscle attaches to the oblique line of the thyroid cartilage?

• Mylohyoid
• Sternothyroid
• Sternohyoid
• Geniohyoid

Q3. Which muscle arises from the oblique line of the thyroid cartilage and elevates the larynx?

• Thyrohyoid
• Omohyoid
• Digastric
• Stylohyoid

Q4. Which pharyngeal muscle has attachment to the oblique line of the thyroid cartilage?

• Inferior pharyngeal constrictor
• Salpingopharyngeus
• Stylopharyngeus
• Superior pharyngeal constrictor

Q5. Where do the vocal ligaments attach anteriorly?

• Outer surface of the cricoid lamina
• Inner surface of the thyroid cartilage near the midline
• Superior horn of the thyroid cartilage
• Apex of the epiglottis

Q6. Which ligament anchors the petiole of the epiglottis to the thyroid cartilage?

• Vocal ligament
• Cricotracheal ligament
• Hyoepiglottic ligament
• Thyroepiglottic ligament

Q7. What type of joint is the cricothyroid joint?

• Primary cartilaginous joint
• Syndesmosis
• Synovial joint
• Fibrous suture

Q8. What movement at the cricothyroid joints contributes to increased vocal fold tension?

• Elevation of the epiglottis alone
• Tilting of the thyroid cartilage relative to the cricoid
• Fusion of the arytenoid to the thyroid
• Separation of the hyoid from the tongue

Q9. Which nerve and vessels pierce the thyrohyoid membrane near the thyroid cartilage?

• Internal laryngeal nerve and superior laryngeal vessels
• Hypoglossal nerve and lingual vessels
• Recurrent laryngeal nerve and inferior thyroid vessels
• External laryngeal nerve and facial vessels

Q10. Why is the laryngeal prominence generally more pronounced in adult males?

• The cricoid cartilage becomes paired
• The superior horns fuse to the hyoid
• The thyroid laminae commonly meet at a more acute angle
• The epiglottis ossifies completely
