Actinomere
Definition
An anatomical segment or structural zone within a body exhibiting radial symmetry, corresponding to one of the repetitive sections arranged around the central axis. In invertebrate zoology, the term describes each of the similar radial segments making up the body of certain echinoderms (such as the arms of starfish) or coelenterates, including the internal organs and skeletal structures associated with that section.
