]> Td5 neuroblast Numbering also indicates relative position: we follow the nomenclature of Urbach et al. (2003), in which neuroblasts are numbered from anterior-to-posterior and ventral-to-dorsal (so that numbers reflect relative positions along the dorsoventral axis). Figure 1 of Urbach et al., 2003, provides a survey of the spatial organization of the embryonic head and brain neuroblasts of a stage 11 embryo.
