Human Embryo Week 4 - Neural Plate to Tube

Week 4 (22 - 23 days), Carnegie stage 10, 2 - 3.5 mm, Somite Number 4 - 12

View: This is a similar dorsal view of two separate embryos, amniotic membrane removed. Left embryo is an early stage 10 with broad neural plate. Right embryo is late stage 10 with plate folding to a neural groove.

Features: Somite Number 4 - 12, rostral neuropore, neural folds in region of developing brain, neural tube, somites, caudal neuropore, neural fold fuses, remnant of amniotic sac

Identify: rostral neuropore, neural folds in region of developing brain, neural tube, somites (note the different number formed), caudal neuropore, neural fold fuses, cut edge of amniotic sac

Events
Ectoderm: Neural fold deeepens, edges approach midline, neural fold fuses, neural plate folds ventrally in brain region

Mesoderm: Somitogenesis, continued segmentation of paraxial mesoderm (4 - 12 somite pairs)
