Intermediate Thyroid Cartilage Quiz

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

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

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

• Mylohyoid
• Sternohyoid
• Geniohyoid
• Sternothyroid

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

• Thyrohyoid
• Stylohyoid
• Digastric
• Omohyoid

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

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

Q5. Where do the vocal ligaments attach anteriorly?

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

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

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

Q7. What type of joint is the cricothyroid joint?

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

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

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

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

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

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

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