Human Heart

 

I.  Heart wall and associated membranes:

 

1. Parietal pericardium
2. Pericardial cavity
3. Visceral pericardium (epicardium)
4. Myocardium
5. Endocardium

 

II.  Chambers of the heart and associated structures:

 

1. Right atrium
2. Left atrium
3. Interatrial septum
4. Fossa ovalis
5. Pectinate muscle
6. Right auricle
7. Left auricle
8. Right ventricle
9. Left ventricle
10. Interventricular septum
11. Atrioventricular (coronary) groove (sulcus)
12. Anterior interventricular groove (sulcus)
13. Trabeculae carnae - interlacing bundles of muscle within the ventricles near the apex
14. Moderator band - muscle bundle between the right ventricle wall and the interventricular septum; serves as an internal brace
15. Apex
16. Base
17. Adipose tissue
18. Trachea

 

III.  Great vessels and valves of the heart:

 

1. Superior vena cava
2. Inferior vena cava     
3. Coronary sinus
4. Tricuspid valve (right atrioventricular [AV] valve)
5. Pulmonary semilunar valve
6. Pulmonary trunk
7. Right pulmonary aa.
8. Left pulmonary aa.
9. Right pulmonary vv.
10. Left pulmonary vv.
11. Bicuspid valve (left atrioventricular [AV] valve; mitral valve)
12. Chordae tendineae
13. Papillary muscles
14. Aortic semilunar valve
15. Openings to the coronary arteries (2)
16. Ascending aorta
17. Aortic arch
18. Descending aorta

 

IV.  Other structures to know:

 

1. Brachiocephalic artery
2. Left common carotid artery
3. Left subclavian artery
4. Ligamentum arteriosum
5. Coronary arteries (in general)
6. Cardiac veins (in general)
7. Opening to the coronary sinus (look inside the right atrium)

 

V.  Conduction system of the heart:

 

1. Sinoatrial (SA) node
2. Atrioventricular (AV) node
3. Atrioventricular (AV) bundle (Bundle of His)
4. Right and left AV bundle branches
5. Purkinje fibers
