From Embryology

This Embryology category shows pages and media related to embryonic development in week 6, 42 - 44 days, GA week 8. The embryos have a crown rump length (CRL) of 11 - 14 mm. Stage 16 and 17 are the only two stages occurring in week 6 of the historic 23 Carnegie stages of embryonic development.


There is also a specific Carnegie stage 17 resource page. See also Carnegie Stage 17 - Events.
