What is the visceral pleura?

A

covers the lungs and is adherent to all its surfaces

1
Q

The visceral and parietal layers of pleura are continuous, forming what?

A

pleural sac

2
Q

What is the parietal pleura?

A

lines the pulmonary cavities, adhering to the thoracic wall, the mediastinum, and the diaphragm

3
Q

The pleural sleeve encloses what structure?

A

root of the lung

4
Q

Where is the pulmonary ligament?

A

inferior to the root of the lung, extending between the lung and the mediastinum

5
Q

What is the pleural cavity?

A

the potential space between the viscera and parietal layers of pleura

6
Q

What are the four parts of the parietal pleura?

A

costal, mediastinal, diaphragmatic, and cervical

7
Q

What is the costal part of the parietal pleura?

A

covers the internal surfaces of the thoracic wall and is separated from the wall by endothoracic fascia

8
Q

What is the mediastinal part of the parietal pleura?

A

covers the lateral aspects of the mediastinum

9
Q

What is the diaphragmatic part of the parietal pleura?

A

covers the superior surface of the diaphragm on each side of the mediastinum

10
Q

What is the cervical pleura of the parietal pleura?

A

extends through the superior thoracic aperture into the root of the neck 2 to 3 cm superior to medial third of the clavicle to the level of the neck of the 1st rib

A

3; 2

12
Q

Where is the cardiac notch?

A

anterior margin of the left lung

13
Q

What is the lingula?

A

process of the superior lobe of the left lung that extends below the cardiac notch

14
Q

What is the apex of the lung?

A

blunt superior end of the lung ascending above the level of the 1st rib into the root of the neck

15
Q

Where is the costal surface of the lungs?

A

adjacent to the sternum, costal cartilages, and ribs

16
Q

Where is the mediastinal surface of the lungs?

A

the hilum of the lung and related medially to the mediastinum and posteriorly to the sides of the vertebrae

17
Q

Where is the diaphragmatic surface of the lungs?

A

on the convex dome of the diaphragm

18
Q

What structures are at the root of the lungs?

A

main bronchus, pulmonary vessels, bronchial vessels, lymphatic vessels, and nerves

19
Q

Where is the pulmonary artery locate in the root?

A

superiormost on the left

20
Q

Where are the superior and inferior pulmonary veins located in the root?

A

anteriormost and inferiormost, respectively

21
Q

Where are the bronchus located at the root?

A

against and approximately in the middle of the posterior boundary, with bronchial vessels immediately surrounding it

22
Q

Where does the left bronchial artery arise?

A

thoracic aorta

23
Q

From where can the right bronchial artery arise?

A

superior posterior intercostal artery, common trunk from the thoracic aorta with the right 3rd posterior intercostal artery, or left superior bronchial artery

24
Q

From where are the nerves of the lungs and visceral pleura derived?

A

pulmonary plexuses located anterior and (mainly) posterior to the root of the lungs
