Introduction

Stage10 bf1c.jpg

Facts

Week 4, 22 - 23 days, 2 - 3.5 mm, Somite number 4 - 12

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

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)

Identify

The 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.
