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, Right embryo is late stage 10.

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)
