Introduction

Size comparison embryo-fetus.jpg

This page is a link to images from a 10 week female fetus approximately 40 mm in size.

Category:Week 10

This stage of development is after the embryonic period (up to week 8), but only 2 weeks into early fetal development.

The fetal period is a time of extensive growth in size and mass as well as differentiation of organ systems established in the embryonic period. In particular, the brain continues to grow and develop, the respiratory system differentiates, the urogenital system further differentiates between male/female, endocrine and gastrointestinal tract begins to function.

Compare this 10 week fetus with the earlier Carnegie stage embryos: size, head/body proportions, brain, head, skeletal development.

Note that in the early fetus the midgut remains herniated and will only be taken into the peritoneal cavity on further body wall growth.
