16
Q

Where is the aortic orifice?

A

left ventricle

17
Q

What are floating ribs?

A

have no direct articulation to the sternum
articulate to the sternum via another costal ribs cartilage

18
Q

External intercostal muscles

A

attach at the spine and run in between the ribs
help with forced inspiration and have a tonal role by crating a pressure barrel

19
Q

Superior mediastinum

A

between the lungs and extends all the way to the thoracic vertebrae
contains the aortic arch, sternal angle, trachea, rib II

20
Q

Inferior mediastinum

A

split into anterior, middle and posterior which are the areas in front of the heart, the heart itself and the area behind the heart

21
Q

Where is the transthoracic plane?

A

border between inferior and superior mediastinum
where the trachea splits into two bronchi

22
Q

Where are the semilunar valves?

A

between the ventricles

23
Q

Where does the superior and inferior vena cava enter the heart?

A

right atrium

24
Q

Where do the pulmonary veins enter the heart?

A

left atria

25
Q

Chordi tendinae

A

lie within the ventricles and are cartilaginous, fibrous structures that are linked to papillary muscles
important role in regulating the pressure within the heart by preventing the flipping of the valves

26
Q

Papillary muscles

A

subset of trabeculae carnae
three in right ventricle, two in left

27
Q

Trabeculae carnae

A

ridges in the ventricles which help with conduction of the heart and stroke volume

28
Q

What determines whether a heart is right or left dominant?

A

supply of the intraventricular artery

29
Q

Left coronary artery branching

A

branches off into left anterior interventricular artery which goes down the front, when then curves around to become the circumflex artery

30
Q

Right coronary artery branching

A

marginal branch which loops around the posterior

31
Q

What is the fossa ovalis?

A

embryological remnant of the foramen ovale which is a hole in the septum of the heart from not using our lungs
closes when we take our first breath

31
Q

What mediastinal structures lie in close proximity to to the left lung?

A

heart
arch of aorta
thoracic aorta
oesophagus

32
Q

What mediastinal structures lie in close proximity with the right lung?

A

oesophagus
heart
inferior and superior vena cava
azygous vein

33
Q

What lung is slightly smaller? Why is this?

A

left lung, due to the presence of the heart

34
Q

What two fissures divide the lobes of the right lung?

A

Oblique fissure- runs from inferior border of the lung in a superposterior direction
Horizontal fissure- runs horizontally from the sternum at the level of the 4th rib

35
Q

What is the lung hilum?

A

Where structures enter and leave the lung- the lung root
wedge shaped area on the mediastinal surface

36
Q

What structures does each lung root contain?

A

bronchus
pulmonary artery
two pulmonary veins
bronchial vessels
pulmonary plexus of nerves
lymphatic vessels
