3

What level of the vertebra does the larynx become the trachea?

C6

4

C6

5

From superficial to deep, name the parts of the chest wall?
(the soma)

Bone/joints
Parietal pleura

6

What fluid does the pleura secrete?

Pleural fluid

7

What is the function of the pleural fluid?

Lubrication
Provides surface tension

8

Name the lobes and fissures of the right lung?

Lobes: superior, middle, inferior
Fissures: horizontal and oblique

9

Name the lobes and fissures of the left lung?

Lobes: superior, inferior
Fissures: oblique

10

How many bronchopulmonary segments does each lung have?

10

11

The sternal angle is at the level of what rib?

Rib 2
T4/5

12

What are the spaces between each rib called?

intercostal spaces

13

Describe the 12 thoracic ribs.

1-7: True ribs
8-10: False ribs
11+12: Floating ribs

14

What is the name of the combined lower costal cartilages?

costal margin

15

The ribs articulate with the sternum via what?

the rib's costal cartiglage

16

What is the name of the joints that join the rib to the vertebra?

Costovertebral joints

17

What is the name of the joints that join the rib to costal cartilage?

Costochondral joints

18

What is hte name of the joints that join the sternum to the costal cartilage?

Sternocostal joints
(synovial)

19

What are the 3 layers of skeletal muscles located between the ribs?

external intercostal muscle
internal intercostal muscle
innermost intercostal muscl

20

what are the muscles of passive breathing?

diaphragm
intercostal muscles

21

What is the blood supply of the anterior parts of the intercostal spaces?

Internal thoracic artery and veins
(run parasternally)

22

What is the blood supply of the 11 pairs of intercostal spaces?
(ie chest wall?)

bilateral posterior intercostal arteries

23

What is the arterial blood supply for the lungs?

bronchial arteries

24

where do the bronchial arteries arise from?

thoracic aortas anterior surface

25

There are 2 domes of the diaphragm. Which dome is more superior?

the right dome due to the presence of the liver inferiorly

26

What type of muscle is the diaphragm?
(skeletal or smooth)

skeletal muscle

27

What is the muscular part of the diaphragm's nerve supply?

phrenic nerve
(combined C3,4,5 anterior rami)

28

What is the route of the phrenic nerve?

-Anterior surface of the scalenus anterior
-Lateral aspects of the fibrous pericardium

29

During inspiration, how does the diaphragm move?

Contracts and descends thus increasing the vertical chest cavity dimension

30

During inspiration how do the intercostal muscles move?

Contract, elevating the ribs and pulling the ribs laterally and anteriorly thus increasing AP and lateral chest caivty dimensions
