---|---|---|
7 | 15 to 17 | notochordal process directly rostral to the area of gastrulation. |
8 to 10 | 17 to 23 | group of undifferentiated cells that briefly persists. Within the notochordal process, a connection between the amniotic cavity and yolk-sac (neurenteric canal). |
8 to 11 | 17 to 26 | notochordal process incorporates entirely into the endoderm, forming the epithelial notochordal plate. |
10 to 11 | 21 to 26 | notochordal plate then acquires an “inverted U-shape”, relatively lengthens during these stages and remains intimately associated with the neural tube until stage 12 (26–30 days). |
12 | 26 to 30 | notochordal plate detaches completely from the endoderm to form the definitive notochord. |
12 to 14 | 26 to 35 | definitive notochord formation then allows the paired dorsal aortae to fuse in-between the notochord and the roof of the gut. |
