Answer 6

Posterior Border: tall/columnar
Anterior Border: floppy
Inferior Border

Question 7

What are some unique features found on the left lung?

Answer 7

Cardiac Notch (superior lobe)
Lingula

Question 8

What is pleura?

Answer 8

Serous membrane that lungs stick to

Question 9

Should the pleural cavity be a real space?

Answer 9

NO!

Question 10

What are the different types of parietal pleura?

Answer 10

1) Cervical Pleura
2) Costal Pleura
3) Diaphragmatic Pleura
4) Mediastinal Pleura

*lines thoracic wall

Question 11

Where is visceral pleura found?

Answer 11

On the lungs (very shiny)

Question 12

What is pleuritis?

Answer 12

Inflamed pleura that can cause friction, leading to more serious issues

Question 13

What is a pneumothorax?

Answer 13

Rupture in thoracic wall and parietal pleura allows air to into pleural cavity, collapsing the lung

Question 14

What are lines of pleural reflection?

Answer 14

Where pleura changes its name (not too imp)

Question 15

How does air reach the lungs?

Answer 15

1) Larynx
2) Trachea
3) Bronchi
4) Bronchioles
5) Alveolar Duct

Question 16

What are the classifications of bronchi?

Answer 16

1) Main Bronchi
2) Lobar Bronchi (2 in left lung, 3 in right lung)
3) Segmental Bronchi

Question 17

What are the classifications of bronchioles?

Answer 17

1) Conducting Bronchiole
2) Terminal Bronchiole
3) Respiratory Bronchiole

Question 18

What is the physiology behind asthma?

Answer 18

• Smooth muscles tighten

- Smooth muscles walls are thickened and inflamed –> airway is swollen during asthma attack

Question 19

In the right lung, what are the bronchopulmonary segments of the superior lobe?

Answer 19

Apical
Posterior
Anterior

Question 20

In the right lung, what are the bronchopulmonary segments of the middle lobe?

Answer 20

Lateral

Medial

Question 21

In the right lung, what are the bronchopulmonary segments of the inferior lobe?

Answer 21

Superior

All basal segments

Question 22

In the left lung, what are the bronchopulmonary segments of the superior lobe?

Answer 22

Apical
Posterior
Anterior
Lateral
Medial

Question 23

In the left lung, what are the bronchopulmonary segments of the inferior lobe?

Answer 23

Superior

All basal segments

Question 24

Which lobe are foreign objects more likely to get stuck?

Answer 24

Right main bronchus

-shorter, wider, and more vertical

Question 25

What innervates parietal pleura?

Answer 25

Intercostal nerves

Question 26

What is endothoracic fascia?

Answer 26

Layer of loose connective tissue deep to the intercostal spaces and ribs

• separates these ribs/muscles from underlying pleura
• outermost membrane of the thoracic cavity
