  3. 3. The left main bronchus: 1 has the aortic arch as an immediate superior relation T 2 contains yellow elastic cartilage in its wall F 3 is usually shorter than the right main bronchus F 4 usually pursues a more vertical course than the right main bronchus F 5 is located posterior to the descending thoracic aorta F
  4. 4. The Trachea: 1 commences at level of the 3rd cervical vertebra, normally 2 normally, has an inner lining of stratified squamous epithelium 3 has a wall that consists of horse-shoe shaped bars of yellow elastic cartilage 4 is derived, embryologically from the foregut 5 derives its sensory innervation from the recurrent laryngeal nerve
  5. 5. The Trachea: 1 commences at level of the 3rd cervical vertebra, normally F 2 normally, has an inner lining of stratified squamous epithelium F 3 has a wall that consists of horse-shoe shaped bars of yellow elastic cartilage F 4 is derived, embryologically from the foregut T 5 derives its sensory innervation from the recurrent laryngeal nerve T
  6. 6. On comparing the left and right main bronchi which of the following observations are true? 1 the left main bronchus is more vertical than the right one 2 he right main bronchus is larger (wider) than the left one 3 the right main bronchus is longer than the left one 4 when performing a rigid bronchoscopy it is easier to enter the right main bronchus than the left one 5 inadvertently aspirated small solid objects are more apt to lodge in the left main bronchus than the right one
  7. 7. On comparing the left and right main bronchi which of the following observations are true? 1 the left main bronchus is more vertical than the right one F 2 he right main bronchus is larger (wider) than the left one T 3 the right main bronchus is longer than the left one F 4 when performing a rigid bronchoscopy it is easier to enter the right main bronchus than the left one T 5 inadvertently aspirated small solid objects are more apt to lodge in the left main bronchus than the right one F
  8. 8. Concerning the Trachea: 1 the tracheal bifurcation lies at the level of the 5th thoracic vertebra 2 typically, the thyroid isthmus over lies the 6th, 7th and 8th tracheal rings 3 the trachea derives its blood supply from the inferior thyroid artery 4 the tracheal wall possesses strips of hyaline cartilage 5 the trachea has an inner lining of columnar epithelium
  9. 9. Concerning the Trachea: 1 the tracheal bifurcation lies at the level of the 5th thoracic vertebra T 2 typically, the thyroid isthmus over lies the 6th, 7th and 8th tracheal rings F 3 the trachea derives its blood supply from the inferior thyroid artery T 4 the tracheal wall possesses strips of hyaline cartilage T 5 the trachea has an inner lining of columnar epithelium T
  10. 10. The right main bronchus: 1 divides into three lobar (secondary) bronchi 2 has a lining of ciliated epithelium 3 gives off the middle lobe bronchus as its earliest branch 4 is wider than the left main bronchus 5 s crossed superiorly by the arch of the accessory hemiazygos vein
  11. 11. The right main bronchus: 1 divides into three lobar (secondary) bronchi T 2 has a lining of ciliated epithelium T 3 gives off the middle lobe bronchus as its earliest branch F 4 is wider than the left main bronchus T 5 s crossed superiorly by the arch of the accessory hemiazygos vein F
  12. 12. Concerning the Trachea and its relations: 1 the oesophagus is an immediate anterior relation 2 the aortic arch is an immediate anterolateral relation 3 the inferior thyroid veins are immediate anterior relations 4 the thyroid isthmus overlies the 7th and 8th tracheal rings 5 the thoracic duct adheres to the posterior aspect of the trachea
  13. 13. Concerning the Trachea and its relations: 1 the oesophagus is an immediate anterior relation F 2 the aortic arch is an immediate anterolateral relation T 3 the inferior thyroid veins are immediate anterior relations F 4 the thyroid isthmus overlies the 7th and 8th tracheal rings T 5 the thoracic duct adheres to the posterior aspect of the trachea F
  14. 14. The Trachea: 1 commences at the level of the lower border of the thyroid cartilage 2 commences at the level of the 4th cervical vertebra 3 commences at the level of the sternal (jugular) notch 4 is in contact with the apical pleura of the left lung 5 is overlapped by the thyrohyoid muscle
  15. 15. The Trachea: 1 commences at the level of the lower border of the thyroid cartilage F 2 commences at the level of the 4th cervical vertebra F 3 commences at the level of the sternal (jugular) notch F 4 is in contact with the apical pleura of the left lung F 5 is overlapped by the thyrohyoid muscle F
  16. 16. The right main bronchus: 1 commences at the level of the 3rd thoracic vertebra 2 has a lining of stratified squamous epithelium 3 is posterior to the ascending aorta 4 is longer than the left main bronchus 5 is crossed anteriorly by the phrenic nerve
  17. 17. The right main bronchus: 1 commences at the level of the 3rd thoracic vertebra F 2 has a lining of stratified squamous epithelium F 3 is posterior to the ascending aorta T 4 is longer than the left main bronchus F 5 is crossed anteriorly by the phrenic nerve T
  18. 18. Concerning the Tracheobronchial tree 1 a bronchopulmonary segment refers to a portion of lung supplied by a segmental bronchus and accompanying segmental branch of the pulmonary artery 2 the upper lobe bronchus of the right lung gives rise to four segmental bronchi 3 the lower lobe bronchus of the left lung gives rise to three segmental bronchi 4 the lower lobe bronchus of the right lung gives rise to five segmental bronchi 5 in the recumbent individual the most dependent bronchopulmonary segment is the apical segment of the upper lobe
  19. 19. Concerning the Tracheobronchial tree 1 a bronchopulmonary segment refers to a portion of lung supplied by a segmental bronchus and accompanying segmental branch of the pulmonary artery T 2 the upper lobe bronchus of the right lung gives rise to four segmental bronchi F 3 the lower lobe bronchus of the left lung gives rise to three segmental bronchi F 4 the lower lobe bronchus of the right lung gives rise to five segmental bronchi T 5 in the recumbent individual the most dependent bronchopulmonary segment is the apical segment of the upper lobe F
