adult posterior anterior ventral commissure 2021-01-08T11:00:37Z FBbt:00047136 Adult commissure found at the anterior of the neuromere that crosses the midline posterior to the hemilineage 2A primary neurites (Shepherd et al., 2016; Court et al., 2020). In the prothoracic and mesothoracic neuromeres the axons form a single commissure but in the metathoracic neuromere the axons are pulled apart to form two distinct commissures (Court et al., 2020). It is derived from the larval anterior ventral commissure, which becomes segregated into two (anterior and posterior) adult commissures (Court et al., 2020). pAV VFB:FBbt_00047136 fly_anatomy.ontology adult anterior ventral commissure
