Definition
The light-sensitive, rod-like central structures within the photoreceptor cells of an insect's compound eye that capture incoming light.
Etymology
Derived from the Greek words 'rhabdos' (meaning 'rod') and 'ommas' (meaning 'eye'), the term was coined in the late 19th century to describe these specific microscopic visual structures.
