Scanning EM showing detail of the Neurenteric Canal
Human embryo (Stage 8, day 18) showing the neurenteric canal and nodal cilia.
The neurenteric canal (archenteric canal, blastoporic canal, Braun's canal) is a transient communication that occurs briefly between the neural tube, notochordal canal, and gut endoderm.
The nodal cilia are thought to act to "stir" the overlying fluid layer at the time of gastrulation. This fluid contains secreted morphogens that are moved in one direction and therefore may have a role in establishing the initial embryo left/right axis.
