	Remodelling of the venous pole, including the further induction of myocardial cells, contributes to the development of the atria. In the mouse, myocardial differentiation occurs in the dorsal mesocardium and cells are then recruited to the venous pole. The development of two left to right shunts in the venous system leads to an increase in the right horn of the sinus venosus and consequentially a decrease in left horn by the end of the fourth week (GA 6 week). The sinuatrial orifice correspondingly shifts to the right thus becomes located in the right atrium. Hence the right atrium receives the superior vena cava (SVC) and inferior vena cava (IVC) in the adult. In mice and chicks the left sinus horn develops as the left SVC, however this regresses to form the coronary sinus in humans. Thus the sinus venosus gradually becomes incorporated into the right atrium. It contributes to the smooth walled part of the adult right atrium, referred to as the sinus venarum. The trabeculated right atrium corresponds to the primordial atrium; the division between these structures is indicated by the inner crista terminalis and outer sulcus terminalis.

	The primordial pulmonary vein develops in the dorsal wall of the left atrium. As the atrium increases in size it incorporates more of the branches of the pulmonary vein, culminating in its receiving the four pulmonary veins. The smooth wall of the adult left atrium originated from the primordial pulmonary vein, while the trabeculated wall represents the primordial atrium.

	This presentation will introduce development of the heart from its earliest origins through to the end of the embryonic period. The main morphological changes in the human heart will be shown in the context of the normal human timeline of development.

			Weeks shown above are for clinical [[:File:Advanced_Heart_Development_Timeline_GA.jpg\|Gestational Age]] (GA). Ages shown below are [[:File:Advanced Heart Development Timeline.jpg\|Ovulation Age]] (OA), subtract 2 weeks from GA. If the linked [[Advanced_Cardiac_Embryology\|Advanced]] pages below are too difficult, try starting with the [[Basic_Cardiac_Embryology\|Basic]] or [[Intermediate_Cardiac_Embryology\|Intermediate]] level descriptions of the same events.
