Human Embryo Carnegie stage 11

Carnegie stage 11 25 days, 19 somite pairs

Facts: Week 4, 23 - 26 days, 2.5 - 4.5 mm, Somite Number 13 - 20

View: This is a scanning EM of the embryo ventral posterior view showing the caudal (posterior) neuropore.


The caudal neuropore will close at the level of somite 32-34, completing primary neurulation, below this point secondary neurulation occurs.
