Flashcards in Clinical Anatomy Of Respiration Part 1 Deck (27):
1

What is the Skelton of the chest wall

Clavicle
Scapula
Acromion
Coracoid process
Spine of scapula
12 thoracic vertebrae

2

What dos the adult vertebral column consist of

7 cervical
12 thoracic
5 lumber
5 sacral
4 occygeal

3

Why does vertebrae vary in size in different areas

To do with weight distribution
Larger vertebrae designed to be able to bear more weight than thinner
Coccyx tapers as weight goes to pelvis

4

Why dos the spine have curvature

4. Curves
Primary - thorax and occygeal as when foetus
Secondary - cervical and lumbar

5

What are the features and functions of a typical vertebrae

Inferior and superior articulate processes
Vertebral arch - composed of pedicel and lamina
Vertebral body - weight bearing
Vertebral foramen - spinal chord passes
Spinous process - ligament and muscle attachments
Transverse process - ligament and rib articulations

6

Which ribs are typical

3-9

7

What are the features of a typical rib

On the head = facets to articulate with vertebrae
Tubercle which articulates with transverse process of vertebrae
Angle is the most vulnerable turning point
Costal groove inside the rib
Body

8

What ribs are atypical

1,2,10-12

9

What are the features of rib 1

Shortest broadest most sharply curved
Least likely to fracture
2 transverse grooves scalene tubercle for the subclavian artery and vein
Only one facet on head

10

How do u take a central venous cannulation.

Index in jugular notch
Thumb halfway across clavicle insert needle beneath thumb under clavicle

11

What are the joints of the chest wall

Costovertebral
Intercostal
Sternocostal
Sternockavicular

12

What is the costal margin

Palpable bottom of rib cage

13

What is a true rib

Rib that articulates directly to the sternum 1-6

14

What is a false rib

Rib that indirectly shares am articulation to the sternum with other ribs 7-10

15

What is a floating rib

Ribs that do not articulate to the sternum 11 + 12

16

What is the anatomy of the sternum

Jugular notch
Sternal angle at rib 2
Manubrium
Body
Xiohoid process

17

Where is the cephalic vein situated

Deltlo pectoral groove
Joins auxiliary vein and forms superior vena cava

18

What are some muscles of anterolateral chest wall

Pec major/min
Deltoid
Latussimus dorsi
Serratus anterior (anchors scapula to ribs)

19

What nerve powers the serratus anterior

Long thoracic nerve lies on top of muscle giving innervation

20

What is winged scapula

Paralysis of serratus anterior form injury to long thoracic nerve
Which can't hold scapula to ribs and wall of thorax

21

What are the intercostal muscles

Internal
Innermost
External
Pull ribs closer together

22

What are the two mechanism used to lift the thoracic cavity

Bucket handle mechanism
Pump handle

23

How many intercostal spaces are there

11

24

Where is a neurovascular bundle situated

Between internal and innermost muscle layers

25

What is thorcentesis

Sampling fluid from pleural cavity via intercostal space
Between neurovascular bundle and colaterol one

26

What is a collateral bundle

Smaller neurovascular bundle

27

What are the two parts of the thorax

Chest wall - protect heart and lungs, make movement of breathing, breast tissue

Chest cavity - in chest walls, contain vital organs and major vessels/nerves
