The progression of the ventricular septum over time from its formation to the mature structure. [GOC:mtg_heart]
Ventricular septum development is a complex and crucial process that forms the partition between the left and right ventricles of the heart. This septum, a muscular wall, is vital for ensuring proper blood flow and preventing mixing of oxygenated and deoxygenated blood. The development of the ventricular septum starts early in embryonic development and progresses through a series of precisely coordinated events.
Firstly, the heart tube, which is the initial structure of the heart, undergoes rapid looping and folding, forming distinct chambers, including the ventricles. At this stage, the ventricles are initially undivided. The formation of the ventricular septum begins with the emergence of two bulges, one from the right ventricle and one from the left ventricle, known as the "muscular interventricular septum." These bulges grow toward each other, eventually fusing to create the initial partition between the ventricles.
Simultaneously, a second structure, the "membranous interventricular septum," forms at the junction of the atrioventricular canals and the ventricular chambers. This structure develops from specialized cells called endocardial cushions and contributes significantly to closing the opening between the ventricles.
The fusion of the muscular and membranous septa creates the complete ventricular septum. This process involves a complex interplay of cellular signaling, cell migration, and extracellular matrix remodeling. The growth and fusion of these septa are carefully regulated by genetic and environmental factors, with any disruptions leading to serious congenital heart defects.
As the septum develops, it is essential that the blood flow through the heart is maintained. This is achieved by the presence of temporary openings, such as the foramen ovale, in the atrial septum and the ductus arteriosus, connecting the pulmonary artery and aorta. These openings allow blood to bypass the non-functional lungs and flow directly to the systemic circulation. After birth, when the lungs become functional, these openings close, completing the separation of the circulatory systems.
The development of the ventricular septum is a dynamic and intricate process that involves numerous cellular and molecular events. Understanding this process is crucial for understanding congenital heart defects and for developing potential therapies for these conditions.'
