Lecture 3: Thoracic Pulmonolgy Flashcards
What are the lobes that make up the right lung?
Superior Lobe
Middle Lobe
Inferior Lobe
What fissure(s) are found found in the right lung?
Horizontal Fissure
Oblique Fissure
What are the lobes that make up the left lung?
Superior Lobe
Inferior Lobe
What fissure(s) are found found in the left lung?
Oblique Fissure
In the hilum, the opening with the thickest wall structure is what?
Main bronchus
What borders are found on the lungs?
Posterior Border: tall/columnar
Anterior Border: floppy
Inferior Border
What are some unique features found on the left lung?
Cardiac Notch (superior lobe) Lingula
What is pleura?
Serous membrane that lungs stick to
Should the pleural cavity be a real space?
NO!
What are the different types of parietal pleura?
1) Cervical Pleura
2) Costal Pleura
3) Diaphragmatic Pleura
4) Mediastinal Pleura
*lines thoracic wall
Where is visceral pleura found?
On the lungs (very shiny)
What is pleuritis?
Inflamed pleura that can cause friction, leading to more serious issues
What is a pneumothorax?
Rupture in thoracic wall and parietal pleura allows air to into pleural cavity, collapsing the lung
What are lines of pleural reflection?
Where pleura changes its name (not too imp)
How does air reach the lungs?
1) Larynx
2) Trachea
3) Bronchi
4) Bronchioles
5) Alveolar Duct
What are the classifications of bronchi?
1) Main Bronchi
2) Lobar Bronchi (2 in left lung, 3 in right lung)
3) Segmental Bronchi
What are the classifications of bronchioles?
1) Conducting Bronchiole
2) Terminal Bronchiole
3) Respiratory Bronchiole
What is the physiology behind asthma?
- Smooth muscles tighten
- Smooth muscles walls are thickened and inflamed –> airway is swollen during asthma attack
In the right lung, what are the bronchopulmonary segments of the superior lobe?
Apical
Posterior
Anterior
In the right lung, what are the bronchopulmonary segments of the middle lobe?
Lateral
Medial
In the right lung, what are the bronchopulmonary segments of the inferior lobe?
Superior
All basal segments
In the left lung, what are the bronchopulmonary segments of the superior lobe?
Apical Posterior Anterior Lateral Medial
In the left lung, what are the bronchopulmonary segments of the inferior lobe?
Superior
All basal segments
Which lobe are foreign objects more likely to get stuck?
Right main bronchus
-shorter, wider, and more vertical
What innervates parietal pleura?
Intercostal nerves
What is endothoracic fascia?
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
