obsolete ellipsoid body shell true Anterior-posterior subdivision of the ellipsoid body. This term has been obsoleted because the ellipsoid body is now described as having 4 concentric layers, with the anterior/posterior shells being incorporated into this definition (FBrf0224194 == Ito et al., 2014, Neuron 81(4): 755--765). This term has been replaced by ellipsoid body layer. mc150430 FBbt:00007545 fly_anatomy.ontology ellipsoid body layer
