Streeter developmental horizon
- Streeter developmental horizon
A term borrowed from geology and archeology by Streeter to define 23 developmental stages in young human embryos,
from fertilization through the first 2 months;
each horizon spanned 2–
3 days and emphasized specific anatomic characteristics,
to avoid discrepancies in the determination of age and body dimensions. [
