Flashcards in Pulmonary Anatomy Deck (44):
1

laryngopharynx

-opening of esophagus

2

nasopharynx

-above soft palate

3

visceral pleura

-covers outer surface of lungs
-no sensory innervation

4

Lung Segments
Upper Lobe of L/R Lungs

-Anterior
-Apical
-Posterior

5

Lobes of Lungs

-Right: upper, middle, lower
-Left: upper, lingula, lower

6

Fissures

-Right Lung: horizontal fissure, oblique fissure
-Left Lung: oblique fissure

7

Pectus Excavatum

-funnel chest
-depression of sternum
-(can measure by pouring water into it)

8

Pectus Carinatum

-pigeion breast
-prominent forward projection of sternum

9

Barrel chest

-side to side diameter almost equal to front to back diameter
-classic of emphysema

10

Oropharynx

-base of tongue

11

Most aspirations are into the ____ lung

-Right
-primary bronchus on right is shorter, straighter and wider than left

12

Respiratory bronchioles

-beginning of gas exchange

(17-19th generation)

13

Alveolar Sac

-major part of gas exchange
-has surfactant

(23rd generation)

14

Terminal Bronchioles

-end of conducting airways

(12-16th generation)

15

Alveolar ducts

-gas exchange

(19-22nd generation)

16

Inhalation associated with:

trunk extension

17

Exhalation associated with:

trunk flexion

18

Surfactant

-keeps alveoli open

19

Pleura

-membranous serous sac around lungs
-visceral and parietal layers
-separated by thin serous fluid

20

increased trunk flexion leads to

-decreased inhalation=closed alveoli-->decreased air movement-->increased pneumonia risk

21

Sternocleidomastoid

-CN XI
-elevate sternum during forced inspiration

22

Parietal Pleura

-covers inner surface of chest wall and part of diaphragm and mediastinum
-subdivided based on area covered

23

External Intercostals

-Ventral rami of T1-T12

24

Internal Intercostals

-Ventral rami of T1-T12

25

Serratus Anterior

-Long thoracic nerve
-C5-7, C8

26

7 Accessory Breathing Mm

-SCM
-Scalenes
-Serratus Ant
-Pec major
-Pec minor
-trapezius
-erector spinae

27

Scalenes

-elevate ribs
-C3-C5

28

Pectoralis Minor

-Med pectoral N
-Elevate ribs with deep inspiration

-C6-8

29

Lung Segments
Lower Lobe of Left Lung

-Anterior
-Superior
-Lateral
-Posterior

30

Lung Segments
Lower Lobe of Right Lung

-Basal

-Medial

31

Lung Sements
Middle Lobe of Right Lung

-Medial
-Lateral

32

Trapezius

-CN XI
-ventral rami of C2-4
-Stabilize scap to let serratus ant and pec minor elevate ribs

33

Pectoralis Major

-Med and Lat pectoral Nn
-Draws ribs toward arms to increase volume

-C5-C8

34

Erector Spinae

-Deep inspiration, extends spine to elevate ribs

Dorsal rami of T1-S3

35

37

Diaphragm

-Phrenic Nerve
-C3-5

38

Lung volume in supine

decreased due to shift of abdominal contents

39

Referred Pain:
Mediastinal and Central Diaphragmatic Pleura

-pn in lower neck and shoulder

40

4 Functions of Lungs

-Exchange O2 and CO2
-Help maintain acid-base balance
-Contribute to temperature homeostasis
-Filter & Metabolize Toxic Substances
