cytomere

The structure separating the portions of the contents of a large schizont in the course of schizogony, as in some of the sporozoans undergoing exoerythrocytic asexual division. Cytomeres are caused by complex invaginations of the surface of the schizont, which isolates them; ultimately, cytomeres complete the budding process in the formation of large numbers of merozoites.
