Study Notes
Stages of Development
- Fetus: 56 days after fertilization to birth
- Neonate: birth to 1 month
- Infant: 1 month to 1 or 2 years
- Child: 1 or 2 years to puberty
- Adolescent: puberty to 20 years
- Adult: 20 years to death
Placenta Development
- The embryonic portion of the placenta is derived from the trophoblast of the blastocyst
Neural Development
- The nervous system develops from a neural tube that forms in the ectodermal surface of the embryo
- Neural crest cells are derived from the developing neural tube
- Neural crest cells play a role in the formation of the nervous system
