Telogenesis is primarily defined as the process of cell differentiation that leads to the formation of new organs and tissues in the body. There are numerous synonyms that can be used to describe this complex biological process, including morphogenesis, organogenesis, embryogenesis, and histogenesis. Morphogenesis is the development and formation of the body's shape and structure, while embryogenesis focuses on the development of the embryo from a single cell. Organogenesis refers to the formation and differentiation of organs from primitive cells, and histogenesis is the process of forming tissues from cells. These synonyms can all be used interchangeably to describe the complex process of telogenesis and the development of new structures within the body.
