Definition of rhabdom in English: rhabdom(also rhabdome) noun ˈrabdəʊm-dəm Zoology A translucent cylinder forming part of the light-sensitive receptor in the eye of an arthropod. 〔动〕感杆束；视轴 Example sentencesExamples - The receptors have long fused rhabdoms and are surrounded by a tracheal tapetum.
- Postlarvae settling at the vents have reasonably normal ommatidia, with layered rhabdoms, standard crystalline cones, and faceted external corneas reflective of the zoeal apposition eye.
- Thus, in some parts of the retina the larval rhabdoms are incorporated into the receptor array.
- As mentioned above, the screening pigment is essential; otherwise, the rhabdoms would receive light from all directions, destroying any spatial information.
- In most species that have only a single visual pigment in main rhabdoms as adults, the larval pigment appears to be identical to that of the adult.
OriginLate 19th century: from late Greek rhabdōma, from rhabdos 'rod'.
