The Chorioallantoic Membrane, also known as CAM, is a membrane that plays a crucial role in avian development. This membrane is responsible for supporting the growth and development of the chick embryo inside the egg. Synonyms for chorioallantoic membrane include allantochorion, allantois-chorion, allantois-vitelline membrane, chorioallantois membrane, and yolk sac membrane. These terms are used interchangeably to describe the same structure within the egg. The chorioallantoic membrane is an important area of research in biology, and its study has led to many advancements in understanding embryonic development and the early stages of life in birds.
