Questions and Answers

1.

The lymph nodes found in the hilum of the lung are the:
- A.
  
  Pulmonary lymph nodes
- B.
  
  Bronchopulmonary lymph nodes
- C.
  
  Tracheobronchial lymph nodes
- D.
  
  Bronchomediastinal lymph nodes
- E.
  
  Anterior mediastinal lymph nodes
Correct Answer
B. Bronchopulmonary lymph nodes

Explanation
The bronchopulmonary lymph nodes are located in the hilum of the lung. These lymph nodes are responsible for draining lymphatic fluid from the lungs and surrounding structures. They play a crucial role in filtering and removing waste products, pathogens, and foreign particles from the respiratory system. The bronchopulmonary lymph nodes are closely associated with the bronchi and pulmonary blood vessels, making them an important component of the lung's immune defense system.

When foreign objects are aspirated into the trachea, they will usually pass into the right primary bronchus because:
- A.
  
  It is larger, straighter and shorter than the left
- B.
  
  It is more curved, longer and smaller than the left
- C.
  
  It is straighter, longer and larger than the left
- D.
  
  It is at a 90 degree angle to the trachea
- E.
  
  There really is no good reason
Correct Answer
A. It is larger, straighter and shorter than the left

Explanation
The right primary bronchus is larger, straighter, and shorter than the left, which makes it more likely for foreign objects to pass into it when aspirated into the trachea. This is because the larger size and straighter path offer less resistance and obstruction for the object to pass through. The shorter length also means that the object has a shorter distance to travel before reaching the bronchus.

3.

The left lung is made up of how many lobes?
- A.
  
  1
- B.
  
  2
- C.
  
  3
- D.
  
  4
- E.
  
  5
Correct Answer
B. 2

Explanation
The left lung is made up of two lobes. The lungs are divided into lobes, and the left lung has two lobes while the right lung has three lobes. The lobes are further divided into smaller sections called bronchopulmonary segments. The division of the lungs into lobes allows for efficient oxygen exchange and helps in the functioning of the respiratory system.

The bifurcation of the trachea lies at about the level of the:
- A.
  
  Plane of the sternal angle
- B.
  
  Xiphisternal junction
- C.
  
  Second thoracic vertebra
- D.
  
  Attachment of the 4th costal cartilage to the sternum
- E.
  
  Plane of the jugular notch
Correct Answer
A. Plane of the sternal angle

Explanation
The correct answer is the plane of the sternal angle. The trachea bifurcates at a point known as the carina, which is located at the level of the sternal angle. The sternal angle is the angle formed by the junction of the manubrium and body of the sternum, and it corresponds to the level of the second thoracic vertebra. Therefore, the bifurcation of the trachea occurs at the level of the plane of the sternal angle.

Which structure below leaves the most pronounced impression on the right lung of the cadaver?
- A.
  
  Right vagus nerve
- B.
  
  Azygos vein
- C.
  
  Right phrenic nerve
- D.
  
  Thoracic aorta
- E.
  
  Right common carotid artery
Correct Answer
B. Azygos vein

Explanation
The azygos vein leaves the most pronounced impression on the right lung of the cadaver. This is because the azygos vein is a large vessel that runs along the right side of the vertebral column and drains blood from the posterior thoracic wall. Its close proximity to the right lung causes it to leave a noticeable mark or impression on the lung.

Which of the following describes a Characteristic of the left lung?
- A.
  
  Horizontal fissure
- B.
  
  A groove for the superior vena cava
- C.
  
  Three lobar bronchi
- D.
  
  Lingula of the lung
- E.
  
  A larger capacity than the right lung
Correct Answer
D. Lingula of the lung

Explanation
The lingula of the lung is a characteristic of the left lung. The lingula is a small, tongue-like projection that extends from the upper lobe of the left lung. It is considered an anatomical landmark and is located anterior to the cardiac notch. The lingula helps to separate the superior and inferior lobes of the left lung and is analogous to the middle lobe of the right lung. It is important for understanding the anatomy and function of the left lung.

Which of the following structures/features are likely to be located at the level of the sternal angle?
- A.
  
  Right lobar bronchus
- B.
  
  Left recurrent laryngeal nerve
- C.
  
  Left brachiocephalic vein
- D.
  
  Carinal ridge
- E.
  
  Base of the ascending aorta
Correct Answer
D. Carinal ridge

Explanation
The sternal angle, also known as the angle of Louis, is an important anatomical landmark located at the level of the second rib and the intervertebral disc between the fourth and fifth thoracic vertebrae. The carinal ridge refers to the ridge or prominence found at the bifurcation of the trachea into the right and left main bronchi. Therefore, it is likely to be located at the level of the sternal angle. The other structures/features listed in the question are not typically found at the sternal angle.

A patient was diagnosed with a severe right middle lobe infection of the lung. Where, on the anterior chest wall, would you auscultate the right middle lobe?
- A.
  
  Superior to the middle third of the clavicle
- B.
  
  Sixth intercostal space
- C.
  
  Second intercostal space
- D.
  
  Seventh intercostal space
- E.
  
  Fourth intercostal space
Correct Answer
E. Fourth intercostal space

Explanation
The correct answer is the fourth intercostal space. Auscultation of the right middle lobe of the lung is done at the fourth intercostal space, which is located between the fourth and fifth ribs. This area is on the anterior chest wall and is an appropriate location to listen for abnormal lung sounds associated with a severe right middle lobe infection.

Which of the following best describes the location of the left main bronchus?
- A.
  
  Posterior to the esophagus
- B.
  
  Superior to the arch of the aorta
- C.
  
  Inferior to the arch of the aorta
- D.
  
  Posterior to the thoracic aorta
Correct Answer
C. Inferior to the arch of the aorta

Explanation
The left main bronchus is located inferior to the arch of the aorta. This means that it is positioned below the arch of the aorta in the thoracic cavity.

Regarding the lung, select the correct answer:
- A.
  
  The bronchopulmonary segments are related to secondary bronchi
- B.
  
  The primary bronchus is generally posterior in the hilum
- C.
  
  The pulmonary artery, at the hilum, usually is found anterior and inferior to the bronchus
- D.
  
  The term diaphragmatic pleura usually refers to a visceral layer of pleura
- E.
  
  The horizontal fissure is usually at the level of the 10th rib
Correct Answer
B. The primary bronchus is generally posterior in the hilum

Explanation
The correct answer states that the primary bronchus is generally posterior in the hilum. This means that the primary bronchus, which is the first branch of the trachea leading into the lungs, is usually located towards the back of the hilum. The hilum is the area on the lung where the bronchi, blood vessels, and nerves enter and exit. This information is important for understanding the anatomical positioning of the primary bronchus in relation to the hilum.

The superior, middle and inferior lobes of the right lung have the following number of bronchopulmonary segments, respectively:
- A.
  
  3,2,5
- B.
  
  3,3,4
- C.
  
  2,4,4
- D.
  
  2,3,5
- E.
  
  5,3,2
Correct Answer
A. 3,2,5

Explanation
The correct answer is 3,2,5. This means that the superior lobe of the right lung has 3 bronchopulmonary segments, the middle lobe has 2 segments, and the inferior lobe has 5 segments.
