Detailed dissection of heart

Tricuspid valve viewed from below

The ventricular aspect of the tricuspid valve is displayed by viewing the heart from a position near its apex. The interior of the right atrium is visible through the ostium of the valve.

1 .	Myocardium of anterior wall of right ventricle (cut and elevated)
2 .	Posterior cusp tricuspid valve
3 .	Septal (medial) cusp of tricuspid valve
4 .	Chordae tendineae
5 .	Epicardium of right ventricle
6 .	Posterior papillary muscle
7 .	Trabeculae carnae
8 .	Anterior papillary muscle (attached to reflected flap of ventricular wall)
9 .	Left pointer: Fossa ovalis Right pointer: Border of fossa ovalis
10 .	Right auricle
11 .	Right atrioventricular opening (arrow on drawing indicates interior of right atrium beyond opening)
12 .	Anterior cusp tricuspid valve
13 .	Supraventricular crest
14 .	Area in which right branch of A-V bundle descends into right ventricle (covered by endocardium)
15 .	Septomarginal trabecula (moderator band)
16 .	Septal papillary muscles
