1

What makes up the lung root?

Main bronchus
Pulmonary artery
Pulmonary veins
Pulmonary lymphatic vessels and bronchopulmonary lymph nodes
Pulmonary visceral afferents and autonomic motor nerves

2

Divisions of pericardium

Fibrous pericardium
Serous pericardium (divided into visceral serious pericardium and parietal serous pericardium)

3

What is epicardium another name for

Visceral serous pericardium (secretes pericardial fluid)

4

What happens if pericardial cavity fills with blood?
Names
Treatment for this
Where is the needle inserted

Have haemopericardium and leads to a cardiac tamponade
Pericardiocentesis
Infrasternal angle

5

Transverse pericardial sinus?

Space within the pericardial cavity posterior to ascending aorta and pulmonary trunk

6

Surfaces of the heart

Anterior (sternocostal) surface
Base (posterior) surface
Inferior (diaphragmatic) surface

7

What often shifts the apex beat to the left

Cardiomegaly

8

What vessel sits in the coronary groove (coronary sulcus/ right atrioventricular groove)?
What does this groove mark?

Right coronary artery
The division between the right atrium and right ventricle (tricuspid valve)

9

Is the vagus nerve or phrenic nerve closer to the heart

Vagus nerve

10

What vessel lies in the anterior interventricular groove?
What does this groove indicate?

Left anterior descending artery
Boundary between the 2 ventricles

11

What sits in the posterior atrioventricular groove?
Purpose of this?

Coronary sinus
Receives deoxygenated blood from most of the cardiac veins and drains into the right atrium

12

What normally sits in the posterior interventricular groove?

Posterior interventricular artery
Posterior interventircular vein

13

Where does the azygous vein drain?

SVC

14

What does the interatrial groove indicate

Boundary between the 2 atria

15

What does the coronary arteries do?

Provide an arterial blood supply to the myocardium and epicardium (located just deep to the epicardium usually embedded in adipose tissue)

16

Where do the coronary arteries arise?

From the ascending aorta

17

What normally forms between the right coronary artery and the circumflex artery

A small anastomose

18

Grooves of the heart (5)

coronary groove
left atrioventricular grove
anterior interventricular groove
posterior interventiruclar groove
interatrial groove

19

2 parts of the septum?

Interatrial septum (interatrial groove)
Interventricular septum (interventricular groove)

20

Where is the hole in an atrial septal defect and a ventricular septal defect?

interatrial septum
Interventircular spetum

21

What blood vessels open into the right atrium?

SVC
IVC
coronary sinus

22

Crista termanalis?

Smooth ridge of muscle in the lateral aspect of the RA which represents the junction between the sinus venosus and the heart

23

Ovale fossa?

an oval depression on the lower part of the septum of the right atrium; it is a vestige of the foramen ovale, and its floor corresponds to the septum primum of the fetal heart;

24

Tricuspid valve cusps?

Anterior, posterior and septal

25

Pulmonary valve cusps

Anterior right and left

26

Aortic valve cusps

Right left and posterior

27

Mitral cusps

Anterior and posterior

28

Which valve has sinuses (spaces within he cusps)

Aortic

29

Which sinuses does the coronary arteries arise from

Right and left aortic sinuses

30

Parts of tricuspid and mitral valves

valve Leaflets, tendinous cords, papillary muscles
