Q1. Which ligament connects the cricoid cartilage to the first tracheal ring?

  • Annular ligament
  • Cricotracheal ligament
  • Intertracheal ligament
  • Thyrohyoid ligament

Q2. How does sympathetic stimulation affect the trachea?

  • Stimulates ciliary movement
  • Inhibits mucus secretion
  • Contracts trachealis and constricts airway
  • Relaxes trachealis and dilates airway

Q3. Where are mucous glands predominantly located in the trachea?

  • Serosa
  • Mucosal epithelium
  • Submucosa
  • Adventitia

Q4. What type of muscle fibers make up the trachealis muscle?

  • Cardiac muscle
  • Smooth muscle
  • Skeletal muscle
  • Elastic fibers

Q5. Which structure is closest to the posterior wall of the trachea?

  • Brachiocephalic vein
  • Esophagus
  • Vertebral body
  • Thyroid gland

Q6. Why is the right main bronchus more prone to aspiration?

  • It has a steeper angle
  • It is narrower and longer
  • It is more vertical and wider
  • It lacks cartilage support

Q7. How does the mucociliary escalator function in the trachea?

  • Contracts tracheal muscles to expel mucus
  • Moves mucus upward via cilia
  • Uses alveolar pressure gradients
  • Passively drains mucus downward

Q8. Which artery is a major supplier of blood to the thoracic portion of the trachea?

  • Pulmonary arteries
  • Bronchial arteries
  • Subclavian artery
  • Superior thyroid artery

Q9. What histological feature distinguishes the trachea from the bronchi?

  • Complete cartilage plates
  • Presence of alveoli
  • C-shaped cartilage rings
  • More glandular tissue

Q10. Where does lymphatic drainage of the lower trachea primarily occur?

  • Inferior tracheobronchial nodes
  • Inguinal lymph nodes
  • Superior cervical nodes
  • Axillary lymph nodes
