| == About Carnegie Stages ==
| |
| | |
| Carnegie stages are named after the famous US Institute which began collecting and classifying embryos in the early 1900's. Stages are based on the external and/or internal morphological development of the embryo, and are not directly dependent on either age or size. The human embryonic period proper is divided into 23 Carnegie stages. Carnegie stages are based on the external and/or internal morphological development of the embryo, and are not directly dependent on either age or size. Criteria beyond morphological features include age in days, number of somites present, and embryonic length.

Revision as of 14:48, 19 August 2009
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
Stage 10 Labelled | Stage 10 SEM
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)
