Events
- gall bladder - majority of gallbladder progenitors in 9-11-somite-stage embryos are located in the lateral-most domain of the foregut endoderm at the first intersomite junction level along the anteroposterior axis.[1]
- neural - Formation and closure of anterior neuropore. The rostral extremity of the neural tube closes in embryos with usually about 15-18 somite pairs and defines this stage. The otic pit becomes progressively more indented but not closed, the mandibular process of the 1st branchial arch is clearly visible. The 3rd branchial arch becomes visible late in the stage.
- limb - An increasingly prominent ridge on the lateral body wall, approximately at the level of the 8th-12th somite, indicates the site of the future forelimb bud. Absent: forelimb bud. Embryonic age = 9 dpc (range 8.5-9.75 dpc) 13-20 somite pairs
- heart - Heart tube undergoes looping at E8.5. The second heart field (pharyngeal mesoderm cells) contributes to parts of the right ventricle, the interventricular septum, the venous pole, and the base of the outflow tract.[2] Three heart regions can be identified by the bulging morphology: bulbus cordis (future right ventricle), primitive left ventricle, and common atrial chamber (behind the primitive left ventricle).[3]
