Heart development
Heart Development
Heart development (pronunciation: /hɑːrt dɪˈvɛləpmənt/) refers to the process by which the heart forms in the embryo during prenatal development. This process begins shortly after fertilization and continues throughout gestation.
Etymology
The term "heart development" is derived from the Old English "heorte" for heart and the Latin "developmentum" for development.
Process
Heart development begins with the formation of the cardiac mesoderm, a layer of cells that will eventually form the heart. This is followed by the formation of the cardiac crescent, a horseshoe-shaped structure that will eventually form the heart tube. The heart tube then undergoes a process of cardiac looping, which gives the heart its final shape.
Stages
There are several key stages in heart development:
- Formation of the cardiac mesoderm
- Formation of the cardiac crescent
- Formation of the heart tube
- Cardiac looping
Each of these stages is regulated by a complex network of genes and proteins.
