Stages of development
|
oocyte, zygote, blastomeres, morula, blastocyst
|
|
|
Cleavage produces what developmental structure?
|
Morula
After the zygote has undergone a series of divisions known as cleavage, a morula, composed of 12-16 cells is formed. |
|
|
What process results in repeated divisions of the zygote, producing a large number of small cells called blastomeres that remain a cluster?
|
Cleavage
|
|
|
What developmental structure eventually gives rise to the placenta?
|
Trophoblast
|
|
|
The embryonic disc is comprised of what structures?
|
epiblast and hypoblast
|
|
|
During what process do epiblast cells invaginate at the primitive streak?
|
Gastrulation
|
|
|
Collectively, the endoderm, ectoderm, and mesoderm form what structure?
|
Trilaminar disc
|
|
|
What embryonic structure forms the body's first segments?
|
Somites
|
|
|
This structure lies between the somatic mesoderm and the splanchnic mesoderm and will eventually develop into the serous cavities of the ventral body cavity.
|
Coelom
|
