==Human Embryo Day 8 to 9==

Section through ovum imbedded in the uterine decidua. Semidiagrammatic. (After Peters.) original figure title

* '''am.''' - amniotic cavity
* '''b.c.''' - blood clot, at the site of initial implantation
* '''b.s.''' - body-stalk, or connective stalk later forming the placental cord region with placental blood vessels
* '''ect.''' - embryonic ectoderm that will contribute to embryonic and placental membrane development
* '''ent.''' - entoderm (endoderm), this was the historic term for what we today call endoderm that will contribute to embryo development
* '''mes.''' - mesoderm, consisting of both embryonic mesoderm (in the trilaminar embryonic disc) and extraembryonic mesoderm (outside the trilaminar embryonic disc)
* '''m.v.''' - maternal vessels, spiral arteries that have been opened at their ends
* '''tr.''' - trophoblast, relative to the embryonic disc the outer syncitiotrophoblast and inner cytotrophoblast layers that will contribute to placental development
* '''u.e.''' - uterine epithelium, the epithelial layer that lines the unerus
* '''u.g.''' - uterine glands, the glands that secrete nutrients to support the initial growth both before and after implantation
* '''y.s.''' - yolk-sac, the endoderm lined and extraembryonic mesoderm covered cavity that will contribute to the gastrointestinal tract, blood and blood vessels
