1

What level is the transverse thoracic plane?

T4/5

2

What is the thymus?

A gland/lymphoid tissure producing T lymphocytes in childhood but becomes involuted to adipose tissue in adult hood

3

What level does the trachea bifurcate?

T4/5 ( at the level of the sternal angle)

4

Name the branches of the thoracic aorta's anterior surface?

Bronchial
Oesophageal
MEdiastinal
Pericardial
Phrenic

5

Where does the azygous vein branch from?

The superior vena cava

6

What drains into the left venous angle?

Thoracic duct

7

What drains into the right venous angle?

Right lymphatic duct

8

Name the two groups of lymoh nodes in the lung?

Tracheo-bronchial
Bronchopulmonary

9

What is the cisterna chyli?

The swollen start of the thoracic duct in the abdomen

10

Where does the phrenic nerve supply the diaphrgam?

Passes with the IVC into the abdomen and supplies the diaphragm fromt eh inferior aspect

11

Name the reminant of the ductus arteriosis?

Ligamentum arteriosum

12

Which nerve is most lateral in the chest?

Phrenic

13

Which is nerve is most medial in the chest?

Recurrent laryngeal nerve

14

What is a central vein?

Close to the heart such that the pressure in them is very similar to the right atrium

15

What is charateristic of the JVP

visable double pulsation
Not palpable
reflects the pressure in the RA
Should be no more than 3 cm above sternal angle

16

Where does the right recurrent laryngeal nerve hook under?

The right subclavian artery
DOES NOT ENTER THE CHEST

17

Where does the left recurrent laryngeal nerve hook under?

Arch of the aorta
DOES ENTER THE CHEST

18

Where do the supraclavicular nerves supply?

C3, C4 dermatome
'shoulder tip'

19

Why can irritation of the diaphragm give you shoulder tip pain?

The nerves of the phrenic and supraclavicular nerves enter the spinal cord at the same levels so the brain 'prefers' the more superficial structure and so feels it as shoulder tip pain

20

What muscles does the left recurrent laryngeal nerve supply?

Muscles of the larynx

21

Where would you insert a needle for pericardiocentesis?

VIa infrasternal angle and directed superioposteriolry, aspirating continuously

22

What is the name of the space which lies posterior to the ascending aorta and pulmonary trunk?

Transverse pericardial sinus

23

What is the name of the depression in the right atrium of the heart which covers the embryological foramen ovale?

Oval fossa

24

Name the other thing we need to know in the RA but have not been told what it is or anything?

Crista terminalis

25

Which valve is bicuspid?

Mitral

26

Where do the coronary arteries arise from?

The right and left aortic sinuses

27

Which valves have papillary muscles?

Mitral and tricuspid

28

What carries fibres of the RBB to the papillary muscle of the anterior cusp?

Moderator band (septomarginal trabecula)

29

Where are the chemoreceptor nerve endings in the heart?

Root of the aorta and IV septum

30

What does the postcentral grus of the parital lobe do?

Somatosensory
Body wall sensations are 'felt'
