They are the outer syncytial layer of the trophoblasts and actively invade the uterine wall. They form the outermost fetal component of the placenta (also known as 'syntrophoblast') and massively increase the surface area available for nutrient exchange between the mother and the fetus. Cells from the syncytiotrophoblast secrete human chorionic gonadotropin. ## Additional images[edit | edit source] * Gray12.png Section through embryonic area of Vespertilio murinus to show the formation of the amniotic cavity. ## See also[edit | edit source] * Syncytium * Cytotrophoblast ## External links[edit | edit source] * Histology image: 19908loa – Histology Learning System at Boston University - "Female Reproductive System: placental villi" * Nature (Journal) Diagram * Musicki B, Pepe G, Albrecht E (1997).
