Flashcards in Anatomy Deck (25):
1

Which nerve runs anterior to hilum and is the most lateral vein (anteriorly)?

Phrenic nerve

2

Which nerve runs posterior to hilum and is the most medial vein (anteriorly)?

Vagus nerve

3

Order of pericardium layers

fibrous pericardium - serous pericardium - pericardial cavity filled with pericardial fluid - visceral serous pericardium

4

What is it called when the heart doesn't beat normally due to increased pressure in the pericardial sac from fluid

cardiac tamponade

5

Bleeding into the pericardial sac

Hemopericardium

6

Pericardia centesis process

needle into the costal angle posterosuperiorly aspirating continuously

7

What is the transverse pericardial sinus?

a 'space' within pericardial cavity, posterosuperiorly.

8

Relation of transverse pericardial sinus to other vessels

posterior to ascending aorta & pulmonary trunk,
finishes anterior to SVC

9

Use in clinical situations

Identify the great vessels before open heart surgery

10

Where is the apex beat?

5th intercostal space at the midclavicular line.

11

What veins joins to make the brachiocephalic veins?

right and left internal jugular veins and subclavian

12

What joins to the SVC?

The brachiocephalic vein

13

The aorta sections

Ascending, Arch, Descending/Thoracic, Abdominal

14

Branches of aorta

Brachiocephalic trunk (right subclavian & right common carotid), left common carotid artery, left subclavian

15

Appendages of heart

auricle (extensions of atrium to allow for blood to be taken on

16

Grooves in the heart

coronary groove on right hand side (holds the RCA)
anterior interventricular groove (boundary between ventricles & holds LAD)

17

What is the coronary sinus and where is it?

the vein that drains all coronary vessels and is located on the base.
It drains into the RA

18

RCA branches

Right marginal artery
Posterior interventricular artery

19

LCA branches

LAD/ anterior interventricular artery
Laterally (diagonally) branch
Left marginal artery (circumflex artery)

20

The walls in the heart names?

Septum
interatrial septum
interventricular septum

21

What is the name of a hole in the wall and how does it cause hypoxia?

Septal defect.
deoxygenated blood mixes and circulates the body and reduces oxygen.

22

The interior of RA

opening of SVC
opening of IVC
opening of coronary sinus
crista terminalis - line of rough to smooth muscle
oval fossa - depression on smooth muscle left from fetal development

23

The of interior ventricles

fibrous skeleton
moderator bands to create a shortcut of electrical currents.

24

Valves & features

Tricuspid (3 cusps & tendonous chords and papillary muscles)
Pulmonary (2 cups)
Mitral (2 cusps & tendonous chords and papillary muscles)
Aortic (2 cup)

25

Why do we auscultate where we do?

No bone and direction of blood flow
