Summary of the video for your notes:
1. The heart is developed from the splanchnic (lateral plate) mesoderm.
2. Atrioventricular endocardial cushions at anterior and posterior walls appear and proliferate until they fuse, turning a single lumen into two. The two canals are the right and left atrioventricular orifices.
3. Once fused, the AV orifices are surrounded by proliferations of mesenchymal tissue.
4. The bloodstream hollows out and thins tissue on the ventricular surface of these proliferations forming the valves and the muscular cords.
5. Muscular tissue in the cords degenerate and is replaced by dense connective tissue.
6. The valves are now connected to thick trabeculae (papillary muscles) by the chordae tendinae.
7. Development of the conotruncal ridges and closure of the interventricular foramen occur by proliferations of the right and left conus cushions, as well as the proliferation of the anterior endocardial cushion - this closes the interventricular foramen and form the membranous portion of the interventricular septum.
Clinical note: Abnormalities in endocardial cushion formation may cause cardiac malformations, including atrial and ventricular septal defects (VSDs) and defects involving the great vessels (for example, transposition of the great vessels, common truncus arteriosus, and tetralogy of Fallot).
Tetralogy of Fallot is one of the more common congenital disorders, classified as a cyanotic heart disorder. It is characterised by four heart defects: (1) pulmonary stenosis, (2) right ventricle hypertrophy, (3) ventricular septal defect, and (4) over-riding aorta (aorta overrides the septal defect).

I am having a hard time understanding the Langman's embrology book. this is a great introduction thanks

[@holden2966]

Don't read it men! That book is so fucking difficult and looooong! Just watch videos

[@tirsoacuna1356]

Langman is just a terrible book for studying embryology. It doesn't even explain the new concepts it introduces you to.

[@pranaydebnath5020]

@@tirsoacuna1356 It's upto people what they like ..just knowledge is important .I like reading langman's .Just I skip that long regulation parts those are not necessary at all and makes chapters long.

[@praveenfernando5394]

Yeah Langman is a pain in the ass. I just watch a video and then try to relate it to the text in the langman. PS senjougahara is best girl.

They eventually become the connective tissue of the septa of the heart, as well as the AV valves.
