Flashcards in Clinical Anatomy Of Respiration Part 2 Deck (19):
1

What kind of muscle is the diaphragm

Skeletal under voluntary control

2

What is visceral pleura

Pleura touching lung (organs)

3

What is parietal pleara

Lines outside of the pleura cav

4

There is a thin layer of a small volume of pleural fluid which creates a ......

Vacuum
Surface tension

5

The visceral and parietal pleura are ___________ at the root of the lung by __________ on itself

Continuous
Reflecting

6

What are the recess of the pleural cavity

Costsodiaphragmatic recesses where excess fluid collects

7

What are the differences between the right and left lung

Right
- 3 lobes (superior, inferior and middle)
- 2 fissures (horizontal and oblique)

Left
- 2 lobes (superior and inferior )
- has a lingula
- 1 fissure (oblique )

8

What is the hilum

Root of the lung

9

What is the phrenic nerve

Combined anterior rami C3,4,5
Found on anterior surface of scalenus anterior descends over heart
Supplies motor and sensory innervation to the diaphragm

10

What is referred pain

Pain in diaphragm felt in neck as tat is where he phrenic nerve originates

11

What are the inspiration mechanics

Diaphragm contracts and descends increase vertical dimension
Intercostal muscles contract elevating ribs
Chest wall pull lungs outwards with them
Air flows in due to -ve pressure

12

What are the expiration mechanics

Diaphragm relaxes and rises decreases vertically
Intercostal muscles relax lowering ribs
Elastic tissues recoil

13

What are the accessory muscles of forced inspiration

Pec major and minor
Scm
Scalene anterior

14

What are some examples where forced inspiration is required

Exercise
Asthma
High altitude

15

What are the accessory muscled for forced expiration

Reacts abdominus
Dia relaxes

16

What is pneumothorax

When air collects in the pleural cavity
Can be traumatic - injury to chest wall allow air through tear in parietal pleura
Spontaneous - ruptured lung

Vacuum lost and cause lungs to collapse

17

If a foreign body is dropped down the trachea where is it most likely to get lodged

Right and left main bronchus
Right is wider shorter and more vertical will pull foreign body to the inferior lobe

18

In a bronchoscopy what is expected to be seen

Trachea
Carina

19

What does the mediastinum contain

Heart and great vessels
