The metamerization of the coelom leads to the axial complex genesis. Mesodermic cells appear besides the stone canal (larva 12 days old): they constitute the axial organ (AO) which develop, in the ventral side, the oral part (PO). This last part corresponds (sensu stricto) to the ancestral lymphoïd organ.
