Flashcards in lungs and pluere Deck (25):
1

What is the general lung morphology?

Apex that reaches thoracic outlet
base that sits on diaphragm
seperated by deep fissures
right is larger than left (cardiac depression)
hilus allows passage of vessels
lungs surrounded by pleural cavity

2

What is the lung morphology of the right lung?

apex ascends above clavicle
Horizontal fissure follows rib 4
oblique fissure found latterally at rib 4 descends to meet rib 6
base is at rib 6 -anteriorly
pleural cavity continues to rib 8 anteriorly

3

What is the morphology of the left lung?

Apex ascends above clavicle
cardiac notch starting at costal cartolage 4
lower limit at rib 6
pleurall cavity continues to rib 8

4

waht connects the parietal layer to chest wall?

endothoracic fascia

5

What forms the hilla?

the reflection of the visceral and parietal layers

6

What are the structural relationships in the right hilum?

main bronchus, posterior
pulmonary artery, anterior
pulmonary vein, anterior and inferior

7

What is the structural relationship in the left hilum?

main bronchus, posterior
pulmonary artery, superior
pulmonary vein, anterior and inferior

8

What is the pulmonary ligament?

extension of the hilum that holds the lower lobes in place

9

What are the three locations where the continuos pleural reflect?

vicseral to parietal - root of lung
costal parietal to mediastinal parietal- anteriorly
costal parietal to diaphrgmatic parietal- inferiorly

10

What is the lingula?

tongue like projection of upper lobe of the left lung

11

What is the cardiac notch?

a notch in the left lung for the heart?

12

Where does the trachea split?

it starts from C7-T4 and splits at T4

13

What is the trachea made up of?

rigid c shaped cartilaginous rings

14

What is the last ring of trachea called?

carina

15

Which bronchial is longer?

left

16

which bronchial has a larger diameter?

right

17

What is the right bronchial divided into?

Main bronchial divides into superior lobar(2) and intermediate lobar
the intermediate lobar divides into middle lobar(2) and inferior lobar(2)

18

What does the left bronchus divide into?

Main bronchus divides into superior lobar(2) and inferior lobar(2)
superior lobar divides into superior division(3) and lingular(3)

19

Segemental branches usually?

tertiary- each branch serves as a bronchopulmonary segment
smallest function of unit
superior lobar and lingular are (3) but not segmental

20

Where does the bronchial artery on the left arise?

thoracic aorta

21

Where does the bronchial artery arise on the right?

third posterior intercostal artery

22

What is the innervation of the visceral pleura?

innervated by visceral afferents that follow from autonomic fibers that follow bronchial vessels

23

What is the course of the lymph?

pulmonary nodes- bronchopulmonary nodes-tracheobronchial nodes - paratracheal nodes.

24

what are the impressions in the right lung?

Subclavian artery
trachea
esophagus
IVC
SVC
cardiac impression
brachioceohalic vein

25

What are the impressions in the left lung?

Trachea
esophagus
arch of the aorta
subclavian artery
brachiocephalic vein
1st rib
cardiac notch
cardiac impression
descending aorta
