| The dissected brain annotated. The optic lobes receive visual input from the two compound eyes. The center of the brain has a mushroom body on each side, where learning and memory occurs in insects. Olfactory inputs go to the antennal lobes. THe esophagus (food canal) goes through the hole formed by the fusion of the subesophageal ganglia with the antennal lobes. The CC-CA complex is located here surrounding the esophagus.

| The CA-CC (corpora allata-corpora cardiaca) complex. The CC is usually milky colored, while the CA is round and clear (the photo here shows more white color due to lighting conditions). CA is the source of juvenile hormone, which regulates division of labor in adult workers. CC stores PTTH (prothoracicotropic hormone) and release it when needed, therefore called a neurohemal organ.
