Q

Valves structure

A

Endothelium
Spongiosa
Fibrosa
Elastin fibres

Then, there is a fibrous ring at the periphery
Rings surrounded by fibrous skeleton

Fibrous skeleton- 1) insulates and 2) anchors muscles and valves

18
Q

Chordae tendinae

A

Thin thread like structures that extend from the papillary muscles and attach to the cusps of the valves

19
Q

Supraventricular crest

A

Between the tricuspid and pulmonary valve, there is a bulging of the right ventricle

20
Q

Aortic sinus

A

A dilatation above the cusp
Two cusps have opening for the coronary arteries
These cusps are called coronary cusps

21
Q

RCA course

A

Between the right atrium and right ventricle
Goes down to the diaphragmatic surface
Goes to the posterior side and branches as posterior interventricular artery between the ventricles
Before that, there is a right marginal branch that goes along the diaphragmatic surface

22
Q

Crux

A

LCA and RCA anastamose at the beginning of the Piv

23
Q

Coronary sinus

A

Major large vein of the heart

24
Q

Innominate veins

A

Two brachiocephalic veins that go into SVC

25
Q

Brachiocephalic veins

A

Right is short and vertical and in line with SVC
Left is longer and oblique
Each is formed by union of subclavian and internal jugular veins

26
Q

Aortic arch

A

Superior mediastinum

27
Q

Descending aorta

A

Posterior mediastinum

28
Q

Brachiocephalic trunk

A

On the right side

Gives rise to subclavian artery and right common carotid

29
Q

Left side of aortic arch

A

Left common carotid

Left subclavian

30
Q

Thoracic outlet

A

The space bounded by the first rib, the first thoracic vertebra and the sternum

31
Q

Above sternal angle at T4

A

Lugwig’s plane

Superior mediastinum

32
Q

Main arterial supply to the thoracic wall

A

Descending thoracic aorta

Through posterior intercostal arteries

33
Q

Posterior intercostal arteries

A

9 pairs- supply blood to bottom 9 intercostal spaces

First 2 are supplied by a branch of the subclavian

34
Q

Internal thoracic artery

A

Branch of the subclavian

Anterior intercostal spaces

35
Q

What continues as the femoral artery

A

External iliac

36
Q

What gives the obturator artery

A

Internal iliac

37
Q

Veins of the thoracic wall

A

Upper intercostal- drain into subclavian system

Lower seven- drain into other veins- Azygos and hemiazygos veins

38
Q

When does oesophagus leave the diaphragm?

A

T8

39
Q

When does the aorta exit?

A

T12

40
Q

Where does internal thoracic artery come from?

A

Subclavian artery

41
Q

When does azygos vein join the SVC?

A

T4

42
Q

Posterior attachment of the diaphragm

A

Crura of the diaphragm- attached to the first two on the left and three on the right

43
Q

Both crura of the diaphragm is joined by which arch and at what level?

A

Median arcuate ligament at T12

Aorta passes through this gap

44
Q

Bifurcation of aorta level

A

L4
