Q

How do the ribs articulate with the vertebrae?

A

The head of the rib articulates with the costal facet on the body of the vertebrae (superior and inferior demifacets)

The TUBERCLE of the rib articulates with the transverse costal facet on the transverse process of the vertebrae

Q

Where does the inferior oesophagus pierce the diaphragm?

A

T10

23
Q

Where does the inferior descending aorta pierce the diaphragm?

A

It doesn’t, it passes behind the diaphragm at T12, in the posterior mediastinum

24
Q

Which pleaura of the lungs hangs down?

A

The parietal pleaura

25
Q

What does the vagus nerve supply?

A

Smooth muscle of the abdominal organs

26
Q

What does the phrenic nerve supply?

A

The diaphragm

27
Q

What is the difference between the pathway of the phrenic nerve and the vagus nerve?

A

Vagus nerve follows the oesophagus

Pherenic nerve follows the pericardium of the heart

28
Q

What is the difference between the right and left lungs?

A

Right has 3 lobes and is slighlty larger

Left has 2 lobes and is smaller

29
Q

What are the relations of the right lung?

A

SVC
IVC
Heart
Oesophagus

30
Q

What are the relations of the left lung?

A

Aortic arch
Thoratic aorta
Heart
Oesophagus

31
Q

In the right lung, what is the level of the horizontal fissure?

A

4th rib

Starts halfway along the oblique fissure

32
Q

What is another name for the sternal angle?

A

Angle of Louis

33
Q

What is another name for the horizontal fissure of the right lung?

A

Transverse fissure

34
Q

What are the borders of the heart?

A

Right to left, top to bottom

UPPER border of 3rd CC
LOWER border of 2nd CC
UPPER border of 6th CC
5th intercostal space

35
Q

Where does the right atrium receive its blood from?

A

Coronary sinus
Superior anf inferior VC
Anterior CARDIAC vein

36
Q

What does the left atrium receive its blood from?

A

2 x superior pulmonary veins

2 x inferior pulmonary veins

37
Q

What are the atria separated by and what does this contain?

A

The inter-atrial septum

Contains the fossa ovalis

38
Q

What is the fossa ovalis?

A

A remnant of the foramen ovale (shunts oxygenated blood from the right atrium to the left atrium in the feotus)

39
Q

Where does the azygos vein run?

A

Alongside the right of the oesophagus (behind the heart)

From its origin at the superior vena cave

40
Q

In the foetus, what provides oxygen to the blood?

A

The PLACENTA (NOT the lungs!!!!)

41
Q

What is the difference between the right atria in the fetus and after birth?

A

In the fetus, it recieves OXYGENATED BLOOD from the placenta

After birth, it recives DEOXYGENATED blood from the rest of the body

42
Q

What are pectinate muscles?

A

Irregular muscles on the inside of the atria (line the auricles)

43
Q

What is the cristae terminalis?

A

A smooth muscle band at the opening of the auricle in the RIGHT atrium

44
Q

Which atria has a tricuspid and which has a bicuspid valve?

A

Tricuspid - right

Bicuspid - left

45
Q

What are trebecular carnae?

A

Mark the inflow of blood - irregular muscle elevations in the ventricles

46
Q

What is the moderator band and where is it found?

A

A projection of the interventricular septum to a papillary muscle at the other side

In the RIGHT ventricle

47
Q

What is the ligamentum arteriosum?

A

Remnant of the ductus arteriosus which shuts blood from the pulmonary artery to the descending aorta - to avoid the lungs

48
Q

Where does the blood from the right ventricle go?

A

To the lungs via the pulmonary trunk

49
Q

Where does the blood from the left ventricle go?

A

To the rest of the body via to aorta

50
Q

Where does the left atrium recieve its blood from?

A

4 x pulmonary veins

51
Q

What gives rise to the coronary sinus?

A

The aortic sinus (directly above the aortic valve)

52
Q

What tells you if you have a left dominant or right dominant heart?

A

Which of the coronary arteries give rise to the posterior interventricular branch

53
Q

Which coronary artery supplies the front apex of the heart?

A

Left

54
Q

Which coronary atery runs in the atrioventricular groove?

A

Right
