archenteron

The roof of the archenteron consists of cells invaginated over the dorsal lip. 3. During neurulation the cells of the dorsal wall of the archenteron form the temporarily existed structures-the back fold and the subnotochord, which soon disappear.

原肠背壁细胞来源于背唇转入层，3.原肠背壁细胞在神经胚形成过程中，形成了短暂存在的原肠背褶和底索。
