1

Layers of pleura and what they touch

Visceral - on the lungs
Parietal - on the surface

2

What is the space between the two layers of pleura and what does it contain?

Pleural cavity
Serous fluid

3

How are two layers of pleura held together?

Surface tension

4

Regions of parietal pleura

Cervical
Costal
Diaphragmatic
Mediastinal
I

5

What are regions of parietal pleura in contact with?

Endothoracic fascia

6

Innervation of parietal pleura and what is it sensitive to?

Phrenic and intercostal
Localized pain

7

Is visceral pleura sensitive to localized pain and what is innervation?

No
Visceral affarent nerves

8

Suprapleural membrane covers which part of parietal pleura?

Cervical

9

Costodiaphragmatic recess

Lowest point of pleural cavity
Recevies drainage of pleural cavity if standing up

10

Costomediastinal recess function

Allows lungs to expand into area during inhalation

11

Hemothorax and where it will drain

Blood in pleural cavity
Costodiaphragmatic recess

12

Pneumothorax and what is can cause

Air in the lung
Collapsed lung

13

Tension pneumothorax causes

Shifting of the mediastinum which can compress a lung

14

Lobes of the right lung and fissures separating

Superior
Middle
Inferior
Horizontal separates sup and mid
Oblique separates mid and inf

15

Lobes of the left lung and fissure

Superior and inferior
Oblique separates

16

2 structures found in superor lobe of left lung

Cardiac notch and lingula

17

Bronchopulmonary segments

Anatomically separate respiratory units surround by connective tissue CONTINUOS with visceral pleura

18

What does each BP segment receive?

A segmental (tertiary) bronchus with accompnaying branch of a pulmonary artery (intrasegmental)

19

Branches of pulmonary veins located

In connective tissue between BP segments (intersegmental)

20

Pulmonary veins and pulmonary arteries carry

Arteries - deoxygenated blood
Veins - oxygenated

21

Sternal angle is at what levle and what is significance

T4...this is where trachea splits to left and right primary bronchus

22

Right vs. left primary bronchus

Right wider and more vertical than left...means objects more likely to go here

23

How many secondary bronchi from each primary branch?

3 on right
2 on left

24

Tertiary bronchi go to

individual BP segments

25

BP segments of right lung superior lobe

Apical
Posterior
Anterior

26

BP segments of right middle lobe

Lateral
Medial

27

BP segments of right inferior lobe

Superior
Medial basal
Anterior B
Lateral B
Posterior B

28

BP segments of left superior lobe

Apicoposterior (1-2)
Anterior
Lingular division has 2 (superior lingular and inferior lingular)

29

BP segments of left inferior lobe

Superior
Medial B
Nateior B
Lateral B
Posterior B

30

Innervation of the lungs

Pulmonary plexuses
Postganglionic symp
Preganglionic parasymp
Visceral afferent
