Sclerosis of the calvarium is hardening of the embryonic or fetal skull.
Before the fetal stage is the embryonic stage. The embryo develops into the fetus.
Most karotyping is done on embryonic or fetal cells.
Conception, embryonic development, fetal development, birth.
The developmental stages of an embryo include the pre-embryonic stage (fertilization to week 2), embryonic stage (weeks 3-8), and fetal stage (week 9 to birth). During the embryonic stage, major organs and structures begin to form, while during the fetal stage, these structures continue to grow and develop in preparation for birth.
Cells change (differentiate) substantially in morphology during embryonic and fetal development.
The development at an early stage for humans is called embryonic development, for pets is called embryonic or fetal development, and for petunias is called seed germination and seedling development.
The three stages of the human life cycle when stem cells can be found are embryonic stage (during early embryonic development), fetal stage (during fetal development), and adult stage (in various tissues and organs throughout adulthood).
The embryonic heart starts beating 22 days after conception
