Introduction

Stage10 bf1c.jpg

Facts: Week 4, 22 - 23 days, 2 - 3.5 mm, Somite Number 4 - 12

View: This is a dorsal view of the embryo. Top embryo is an early stage 10, bottom is late stage 10. Amniotic membrane removed.

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

(note there are 2 separate images of this stage)

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)
