1

Lung apex

3cm above clavicle

2

inferior border of lungs

ML: 4th CC
MC: 6th rib
MA: 8th rib
MS: 10th rib

3

lung pleura

Ribs
2nd Sharp angle inferiorly
4 L shifts laterally for heart
6 both diverge laterally
8 MC
10 MA
12 back

lung is 2 ribs higher

4

Oblique lung fissure

begins at T3 at the back, and moves round to follow line of 6th rib anteriorly

5

Horizontal fissure

Right only

travels anteriorly from MA line, follows 4th intercostal space

6

Trachea bifrucation

T4/5 sternal angle/carnia

7

Upper oesophageal sphincter

C6

8

Gastro-oesophageal junction

T10

9

Right border of the heart

line from right 3rd CC's superior border (2cm from sternal margin) to the 6th CC's junction with the sternum

10

Left border of the heart

marked by a line from the apex beat to the lower border of the left 2nd CC 2cm from the sternal margin

11

Mitral valve

at the apex

12

Tricuspic valve

left sternal edge, 4th intercostal space

13

Aortic valve

2nd right intercostal space

14

Pulmonary valve

2nd left intercostal space

15

Aorta

originates behind sternal angle
leaves mediastinum through D at T12 and gives off celiac axis
gives off superior mesenteric at L1/2
L3 - inferior mesenteric
bifrucates at L4

16

SVC

enters right atrium at 3rd CC

17

Liver

extends within right upper abd from (expiratory) upper limit in the plane beneath the nipples, to an (inspiratory) lower limit in a plane between the right costal margin extended towards left nipple

18

23

Why does thyroid gland need rich blood supply?

deliver sufficient iodine, rapid delivery of TSH and rapid 'washout' of thyroxine

24

fibrous connective tissue

contents:
- internal jugular vein (lateral)
- common carotid and IC (medial)
- vagus nerve (posterior)
- deep cervical lymph nodes
