Q

What is in a neurovascular bundle?

A

Artery, vein and nerve

26
Q

Where does the intercostal NVB sit?

A

In the costal groove

27
Q

What does the head of the rib articulate with?

A

The body of the vertebrae of the same number and the vertebrae superiorly

28
Q

Why does the rib tubercle articulate with?

A

The transverse process of the vertebrae of the same number

29
Q

What is a Sternocostal Joint?

A

Synovial with limited movement

Between sternum and costal cartilage

30
Q

What is a costochondral joint?

A

Not synovial.

Junction between bone and cartilage

31
Q

What is a costovertebral joint?

A

Synovial- limited movement

Between ribs and vertebrae

32
Q

What are the muscles of normal breathing?

A

External, internal and innermost intercostal muscles

The diaphragm

33
Q

How many pairs of intercostal spaces?

A

11

34
Q

Where is the nerve supply of the intercostal muscles?

A

Anterior Ramus of spinal nerve (intercostal nerve)

35
Q

What is the anterior blood supply of the intercostal muscles?

A

Arterial- internal thoracic artery

Venous- internal thoracic vein

36
Q

What is the posterior blood supply of the intercostal muscles?

A

Arterial- Thoracic aorta

Venous- Azygous vein

37
Q

What do the bronchial arteries supply?

A

Lung tissue

38
Q

What does the diaphragm form?

A

Floor of chest cavity and roof of abdominal cavity

39
Q

What is unusual about the diaphragm?

A

Central tendon

40
Q

Why is the diaphragms right done higher?

A

Presence of the liver

41
Q

What are the muscular attachments of the diaphragm?

A

Sternum
Lower 6 ribs and costal cartilages
L1-L6 vertebral bodies

42
Q

What nerve supplies the diaphragm?

A

The phrenic nerve

43
Q

Where is the phrenic nerve found?

A

In the neck on the anterior surface of the scalenus anterior
In the chest descending over the lateral surfaces of the heart

44
Q

What does the phrenic nerve do?

A

Primarily supplies motor innervation but also supplies sensory and sympathetic nerves

45
Q

Excellent lain the process of inspiration

A

Diaphragm contracts and descends and the intercostal muscles contract to elevate the ribs. These increases the chest dimensions.
Chest wall pulls out and air flows in due to the negative pressure.

46
Q

Explain the process of Expiration

A

Diaphragm rises and relaxes and the intercostal muscles relax and the lower ribs fall. Decreases the chest dimensions.
The elastic of the lungs recoil and the air flows out.

47
Q

What are the four quadrants of the breast?

A

Superolateral Quadrant
Infereolateral Quadrant
Superomedial Quadrant
Infereedial Quadrant

48
Q

Describe the unilateral drainage of the breast lymph nodes

A

Drains from the lateral quadrants to axillary nodes.

49
Q

Describe the bilateral drainage of the breast lymph

A

Drainage from medial quadrants to par aster all nodes.

50
Q

What is the supply and drainage of the breast?

A

Internal thoracic artery (branch of subclavian artery)

Internal thoracic artery (drains into subclavian vein)

51
Q

Describe the superficial fascia

A

Adipose tissue- provides insulation

52
Q

Describe the deep fascia

A

Tough fibrous layer- provides protection

53
Q

Where is the cephalic vein situated?

A

In the delta pectoral groove

54
Q

What is the role of the Serratus Anterior?

A

Anchors the scapula to ribs

55
Q

What nerve supplies the serratus anterior?

A

The long thoracic nerve

56
Q

How to winged scapula occur?

A

Paralysis of the serratus anterior- usually through damage to the long thoracic nerve

57
Q

What are the 4 sections of the parietal pleura?

A

Cervical
Costal
Visceral
Mediastinal

58
Q

What is the costodiaphramatic recesses?

A

Most inferior part of the lung upright. Abnormal fluid can drain into recesses causing blunting of the angles on the CXR

59
Q

What surface markings are found in the right lung?

A

Heart, ribs, diaphragm, SVC and azygous vein

60
Q

What surface markings are found on the left lung?

A

Ribs, diaphragm , big heart marking, Aorta
