Human Embryo Carnegie Stage 12

A ventral view of the embryo head region (Carnegie stage 12, week 4, 26 days, 25 somite pairs, CRL 5 mm). Note by this stage, one day later, than the previous stage 11 embryo, the buccopharyngeal membrane has been entirely lost.

Carnegie Stage 12

Facts: Week 4, 26 days, 5 mm, Somite Number 25

View: Ventral view, day 26, 25 somites, amniotic membrane removed

Features: stomodeum (stomatodeum), pharyngeal arch 1, brain fold
