Implantation
Chorionic villi
During implantation, extensions of the trophoblast, the syncytiotrophoblasts, embed within the endometrium and form chorionic villi.
This is a drawing of chorionic villi. The syncytiotrophoblasts are identified within the endometrium and are seen attaching to the uterine wall to form chorionic villi.
