1

How many pairs of ribs are they? what do these articulate with posteriorly?

there are 12 pairs of ribs. these articulate posteriorly with the verterbral column.

2

what do the uppermost ten pairs of ribs articulate with?

articulate posteriorly with the verterbral column and anteriorly with the sternum

3

what are true ribs? which ribs are true ribs?

true ribs are directly attached to the sternum.

these are ribs 1-7

4

what are false ribs? which ribs are false ribs?

these ribs do not directly attach to the sternum.

these are ribs 8- 12

5

which ribs are floating ribs?

ribs 11 and 12

6

where is the sternal angle?

is with the first 4 vetebrae.

7

What are the three parts of the sternum?

the Manubrium

the Body 

the xiphoid process

8

what is the sternoclavicular joint?

it's between the sternum and clavicle

9

what is the clavicle?

the collarbone

10

what is the scapula?

the shoulder blade 

11

what is the pectoral girdle?

the scapula and the clavicle

12

what is the suprsternal notch?

also known as the jugular notch, it is the large visible dip between the nech and the collarbone

13

what is the clavicular notch?

it is a notch on either side of the upper manubrium, this is the site of articulation between the manubrium and clavicle

14

what parts of the rib are there?

The head 

The neck 

the tuberoscity

15

how can you identify the external intercostal muscles?

they face downwards and forwards

16

how can you identify the internal intercostal muscles?

they face upwards and backwards at 90 degrees.

17

what vein, artery and nerve supply the intercostals?

the intercostal vein , the intercostal artery and the intercostal nerve.

18

what does the phrenic nerve supply?

supplies the diaphragm

19

what does the vagus nerve supply?

the thoracic viscera.

20

describe the right lung

3 lobes, two fissures, larger than the left lung.

21

describe the left lung

2 lobes, one fissure, smaller than the right lung. cardiac notch can be seen

22

what is the pericardium of the heart attached to?

the heart and also to the diapragm

23

what comes off of the arch of the aorta?

the brachiocephalic trunk, the left common carotid and the left subclavian.

24

what is the brachicephalic trunk?

the artery of the mediastinum, it supplies the right arm, head and neck.

25

what comes of the brachicephalic trunk?

the right subclavian and right common corotid arteries

26

what do the common carotid arteries supply?

the head and neck

27

what do the subclavian arteries supply and what do these come off?

the right subclavian comes off the brachicephalic trunk and supplies the blood to the right arm with some branches going to the head and neck

the left subclavian comes of the aortta and supplies blood to the left arm

28

what's the role of the superior vena cava?

carries unoxygenated blood to the heart

29

what does the phrenic nerve come from and where does it go to?

goes from the neck, past the heart down to the diaphragm.

30

what does the vagus nerve do?

supplies many organs goes down by the diaphragm

31

what is the hilus of the lung?

it's where the bronchus, the pulmanory artery and the pulmanory vein enter the lungs

32

what is the role of the pulmanory artery?

it brings unoxygenated blood from the right ventricle into the lung

33

what is the role of the pulmanory vein?

it bring oxygenated blood from te lungs to the left atrium

34

on which lung(S) is a superior lobe seen?

on both the right and left lungs

35

 on what lungs is there a middle lobe?

only on the right lung.

36

on what lung(s) is there and inferior lobe?

on both the right and left lung

37

what is the lingula? where is it located?

it is the "little tongue" it is located on the left lung

38

what's the function of the main bronchi?

to bring air into the lungs

39

where does the trachae split into the right and left bronchi?

at T4

40

what is the role of the bronchial arteries?

to supply the lungs with oxygenated blood. usually one to the left and one to the right lung.

41

what does the superior mediastinum contain?(8)

acending aorta

arch of the aorta

brachicephalic trunk 

right and left common carotid arteries

right and left subclavian arteries

internal jugular vein

subclavian vein

brachicephalic vein.

42

what does the posterior mediastinum contain? (8)

the decending aorta

ribs and thoracic vertebra

central tendon of the diaphragm

pulmanory artery

pulmanory vein

bronchus

vagus nerve

phrenic nerve

Which lung is this?

at what throcacic level does this horizontal fissure usually lie?

Q image thumb

the right lung 

this is at the level of the 4th rib

44

which part of the vertabra is this?

Q image thumb

it's the transverse process

45

what is this?

name the three parts of this structure

what is this joint? 

what lies at the level of this joint?

Q image thumb

the sternum

the menubrium, the body and the xiphoid process.

the sternal angle

the level at which the trachea splits into the right and left bronchi.

46

In this picture of the heart and lungs viewed from behind (posterior view) what stucture causes the impression on the left lung indicated by the arrow?

Q image thumb

the descending aorta
