Anatomy and development of the Emys orbicularis heart, Yntema Stage 10

This page gives access to a collection of additional pictures (under Pictures in the menu), animation sequences (under Animations in the menu) and interactive browsing using the 3D model browser (under Interactive in the menu) of heart development at stage 10 of Emys orbicularis. The Index in the menu links to the other developmental stages.

Legends: A, atrium; AA, aortic arch; ACV, anterior cardinal vein; AVC, atrioventricular canal; CA, cavum arteriosum; CAVV, cushion tissue forming the atrioventricular valve; CP, cavum pulmonale; CCV, common cardinal vein; CV, cavum ventrale; DC, distal cushions; F, foramen; HS, horizontal septum; HSt, heart stalk; IAS, interatrial septum; IHC, inner heart curve; IVC, intraventricular canal; LAA, left aortic arch; LA, left atrium; LAVC, left atrioventricular canal; MC, mesenchymal cap; OFT, outflow tract; PA, pulmonary artery; PC, proximal cushions; PCV, posterior cardinal vein; PM, pectinate muscle; PV, pulmonary vein; RAA, right aortic arch; RA, right atrium; SV, sinus venosus; TC, trabeculae carneae; V, ventricle; VS, vertical septum; VV, possible venous valve of the superior cardinal vein.

Yntema stage 10.

At this stage cardiac looping is still in progress and the distal bend of the heart tube is moving towards the apex of the ventricle. The heart can still be seen as one folded tube. In the ventricle trabeculae are still developing and the vertical septum is not yet evident. The cavum arteriosum and cavum venosum cannot be distinguished.

Interactive Visualization

For Interactive Visualization and Manipulation of the Yntema Stage 10 model please use our 3D visualizer.

The interactive vizualization application is a java applet and it reads the model as produced in TDR-3Dbase (Verbeek, 1999). from our server. At the server the model is stored in a database which contains the section images, the structure information and the graphical information. The java applet requires Java 3D to be installed on your system and available for the browser. In case you cannot see the the 3D representation tab please contact your system administrator.The applet is preferably used over a high badwdtih internet connection; the computer should have a good graphics card and sufficient memory.
