Bulbus cordis
Bulbus Cordis
Bulbus cordis (pronounced: BUL-bus KOR-dis) is a structure found in the developing heart of an embryo. The term is derived from the Latin words 'bulbus' meaning 'swelling' or 'bulb', and 'cordis' meaning 'heart'.
Anatomy
The bulbus cordis is one of the five primitive sections of the heart that develops into the right ventricle and outflow tracts of the adult heart. It is located between the primitive ventricle and the truncus arteriosus.
Development
During embryonic development, the bulbus cordis undergoes a process of cardiac looping and remodeling to form the right ventricle and outflow tracts. This process is regulated by a complex network of genetic factors and signaling pathways.

- Primitive ventricle: The portion of the embryonic heart that develops into the left ventricle.
- Truncus arteriosus: The embryonic structure that gives rise to the aorta and pulmonary artery.
- Genetic factors: Genes that influence the development and function of the heart.
- Signaling pathways: Networks of molecules in a cell that work together to control one or more cell functions.
