Detailed dissection of heart
Ventricular myocardium; cardiac valves and ostia, basal view
The atria have been cut off close to their attachments to the atrioventricular valve rings.
1 . Pulmonary trunk
2 . Right semilunar cusp
3 . Anterior semilunar cusp
4 . Left semilunar cusp (together 2-4 make up the pulmonary valve
5 . Nodule of valve
6 . Left coronary artery (at origin from aortic sinus)
7 . Ascending aorta
8 . Left fibrous trigone
9 . Left ventricle
10 . Left atrioventricular opening
11 . Anterior cusp of mitral valve
12 . Posterior cusp of mitral valve
13 . Myocardium left atrium (cut across)
14 . Right fibrous trigone
15 . Atrioventricular bundle (bundle of His)
16 . Posterior interventricular sulcus
17 . Right atrioventricular opening
18 . Conus arteriosus
19 . Left semilunar cusp (aortic)
20 . Upper pointer: Right semilunar cusp Lower pointer: posterior semilunar cusp (of aortic valve)
21 . Right coronary artery (at origin from aortic sinus)
22 . Atrioventricular septum
23 . Anterior semilunar cusp (pulmonary)
24 . Septal (medial) cusp of tricuspid valve
25 . Posterior cusp tricuspid valve
26 . Right ventricle
27 . Myocardium right atrium (cut across)
