part of develops from adult posterior anterior ventral commissure adult metathoracic posterior anterior ventral commissure 2021-01-08T12:13:11Z Commissure found at the anterior of the adult metathoracic neuromere that crosses the midline posterior to the hemilineage 2A primary neurites (Shepherd et al., 2016; Court et al., 2020). It is derived from the larval metathoracic anterior ventral commissure, which becomes segregated into two (anterior and posterior) adult commissures (Court et al., 2020). Unlike in other neuromeres, the axons are pulled apart to form two distinct metathoracic posterior anterior ventral commissures (Court et al., 2020). These are collectively formed of lineages 13B and 14A (Court et al., 2020).
