CHORIONS Meaning and
Definition
-
Chorions refer to the outermost membrane surrounding the embryo in the placental mammals, including humans. It is one of the extraembryonic membranes that develop during pregnancy. The word "chorion" is derived from the Greek word "chorion," meaning "skin" or "membrane."
The chorions are formed from the trophoblast, a layer of cells that originate from the outer part of the blastocyst. These cells begin to differentiate and give rise to the chorion, which plays a crucial role in the development of the placenta. The chorion is responsible for the exchange of nutrients, waste products, and gases between the mother and the developing fetus. It also produces hormones, such as human chorionic gonadotropin (hCG), which is essential for maintaining a healthy pregnancy.
In humans, the chorion develops at the early stages of pregnancy and forms finger-like projections known as chorionic villi. These villi contain a network of blood vessels that facilitate the exchange of materials between the mother and the embryo. As the pregnancy progresses, the chorion fuses with the uterine lining to form the placenta, which provides nourishment and support to the developing fetus.
Overall, the chorions are vital structures in mammalian pregnancies, ensuring proper fetal development and serving as an interface between the mother and the embryo.

Etymology of CHORIONS
The word "chorions" is derived from the Old French word "chorion", which ultimately traces back to the Greek word "khorion" (χορίον). In Greek, "khorion" originally referred to the outer membrane of the fetus during pregnancy. This word, in turn, comes from the Greek word "khoros" (χορός), which means "dancing place" or "open space for dancing". The association between the fetal membrane and dancing likely stems from the swaying, rhythmical movements of the fetus within the womb.
