embryological
Concerning early development
Embryological means relating to embryology—the study of how embryos form and develop.
The term appears in scientific contexts discussing early developmental stages: embryological research, embryological evidence for evolution.
Embryological similarities between species reveal evolutionary relationships that adult forms might obscure.
First embryonic cell
- blastocystEarly developmental stage before implantation
- morulaSolid embryonic cell mass
- ectodermEmbryo's outer cell layer
