ommatidium
ID: FBbt_00004510
Adult Nervous system Sense organ Visual system
One of the facets of the compound eye. It is composed of eight light-sensing photoreceptor cells (photoreceptor cell R1-R8) and accessory cells. There are around 800 ommatidia in each compound eye. (Zombori and Steinmann, 1999, Wernet and Desplan, 2004)
