CHORION LAEVE Meaning and
Definition
-
Chorion laeve is a term primarily used in the field of obstetrics and gynecology to refer to a specific part of the developmental structure known as the chorion.
The chorion is one of the extraembryonic membranes that form during the early stages of pregnancy. It is derived from trophoblastic cells and functions as the outermost protective covering of the fetus. The chorion plays a crucial role in facilitating nutrient exchange between the mother and the developing embryo.
The chorion itself has two distinct layers or regions: the chorion frondosum and the chorion laeve. The chorion frondosum, also called the villous chorion, is the region that forms finger-like projections called chorionic villi, which aid in nutrient absorption and waste removal. On the other hand, the chorion laeve, or the smooth chorion, is the outer part of the chorion that lacks chorionic villi. It is characterized by a smoother appearance compared to the frondosum due to the absence of these finger-like projections.
The presence of chorionic villi in the frondosum is crucial for the process of placentation, the formation and development of the placenta, which is responsible for the exchange of gases, nutrients, and waste materials between the mother and the developing fetus.
Overall, chorion laeve refers to the smooth outer layer of the chorion, while chorion frondosum refers to the region of the chorion that contains chorionic villi.

Etymology of CHORION LAEVE
The term "chorion laeve" is derived from two separate components: "chorion" and "laeve".
1. Chorion: The word "chorion" comes from the Ancient Greek word "khorion", meaning "skin" or "membrane". In medical terminology, the chorion refers to the outermost fetal membrane surrounding the embryo in the uterus during pregnancy. It is a vital part of the placenta, facilitating the exchange of nutrients and waste products between the mother and the fetus.
2. Laeve: "Laeve" is a Latin term meaning "smooth" or "flat". It is an adjective form of the Latin word "laevus", which translates to "left" or "left-handed". In the context of "chorion laeve", "laeve" is used to describe the smooth, non-fatty appearance of the chorion membrane.
