General Information
Term larval abdominal NB2-2 primary interneuron ID (Ontology) FBbt:00001471 (Fly Anatomy)
Definition Larval primary interneuron that develops from NB2-2 of the abdomen. There are about 10 of these cells and they form a bundle that projects through the anterior commissure (Bossing et al., 1996). Compared to the thoracic NB2-2 interneurons, this contralateral bundle is more prominent and it makes an anterior turn after reaching the contralateral connective (Bossing et al., 1996).[ FlyBase:FBrf0090460 ]
Also Known As "2-2I of abdomen"
Comment See Bossing et al. (1996) for a diagram.
