Acrosome -CORRECT ANSWER Cap on sperm.
Cleavage -CORRECT ANSWER Rapid mitotic division beginning after fertilization.
Morula -CORRECT ANSWER 16 cell unit that is formed on day three of cleavage.
Blastocyst -CORRECT ANSWER Developing unit after fluid moves rapidly through it,
dividing cells into inner and outer layer.
Trophoblasts -CORRECT ANSWER Outer layer of cells on the blastocyst that become
the placenta.
Embryoblasts -CORRECT ANSWER Inner layer of cells of the blastocyst that become
the baby.
Chorionic Villi -CORRECT ANSWER Finger-like projections of trophoblasts that attach
to the endometrium, burrowing in until fully covered.
Decidua basalis -CORRECT ANSWER Layer of endometrium that chorionic villi burrow
into; under blastocyst.
Decidua captularis -CORRECT ANSWER Layer that covers blastocyst.
Decidua vera -CORRECT ANSWER Remaining portion of the endometrium that gets
smaller as the baby grows.
Embryo -CORRECT ANSWER Developing baby from Day 15-Week Eight. Most critical
time for development; baby is most vulnerable to teratogens.
Chorion -CORRECT ANSWER Tissue covering of fetal side of placenta.

Human Chorionic Gonadotropin (HCG) -CORRECT ANSWER Maintains estrogen and
progesterone levels; levels decrease after four months. Hormone used to detect

endometrium, stimulates metabolism, and stimulates breast growth.
Estrogen -CORRECT ANSWER Stimulates proliferation of breast and uterus cells and
aids in placental blood flow.
