Brochopulmonary Anatomy

Question 1

At what vertebral level is found the cricoid cartilage?

Answer 1

C6

[just superior to the cricoid are the vocal chords]

Question 2

The brachiocephalic artery bifurcates into which two arteries? And at what vertebral level does this occur?

Answer 2

Subclavian and jugular.

It occurs at TI.

Question 3

What are the three classifications of bronchi?

Answer 3

1. R/L main bronchi
2. Lobar bronchi (3 R, 2L)
3. Segmental bronchi (~10 L/R)

Question 4

Name the point of divergence of the main bronchi.

Answer 4

Carina.

Question 5

Into which part of the lung is a foreign object most likely to fall?

Answer 5

Right Inferior local bronchus

Question 6

At what vertebral level is the bifurcation of the trachea?

Answer 6

T4

Question 7

Name and describe the 3 branches of the aortic arch.

Answer 7

Brachiocephalic (branches to right common carotid/subclavian)

Left common carotid
Left subclavicular

Question 8

Locate the pulmonary ligament.

Answer 8

On the mediastinal surface of both lungs, inferior to the root, as far as the diaphragmatic surface caudally.

Question 9

Of the pulmonary vein and artery which is the uppermost at the root of the lung?

Answer 9

On R/L the artery is uppermost.

Question 10

Describe the position of the heart, aortic arch, and thoracic aorta in relation to the left lung.

Answer 10

On the mediastinal surface, a round hollow inferior and anterior to the root of the lung. Delineated posteriorly by the pulmonary ligament. The hollow is traversed by the oblique fissure.

From the heart the aortic arch loops superiorly around the root superior to the pulmonary artery then down posterior to the root where it travels parallel and lateral to the oesophagus.

Question 11

Name all the lobes of all the lungs.

Answer 11

Right Sup Med Inf

Left Sup Inf

Question 12

Name the 3 segments of the superior lobe of the right lung.

Answer 12

1. Apical
2. Posterior
3. Anterior

Question 13

Name the two segments of middle lobe of the right lung.

Answer 13

1. Lateral

2. Medial

Question 14

Name the five segments of the inferior lobe of the right lung.

Answer 14

1. Superior
2. Posterior basal
3. Lateral basal
4. Anterior basal
5. Medial basal (visible mediastinally)

Question 15

Name the 4/5 segments of the superior lobe of the left lung.

Answer 15

1. /2. Apico/posterior (can be one or two segments)
2. Anterior
3. Superior lingular.
4. Inferior lingular.

Question 16

Name the 5 segments of the inferior lobe of the left lung.

Answer 16

1. Superior
2. Posterior basal
3. Lateral basal
4. Anterior basal
5. Medial basal (absent in 70% pop.)
