Definitions |
The subcommissural organ is a circumventricular organ consisting of ependymal and hypendymal cells which secrete SCO-spondin[WP,partially vetted]. Occurs throughout the vertebartes [PMID:9579598, DOI:10.1002/ar.1091260210]. First appears in hagfish(Olsson). In many species, including the human, it reaches its full development during embryonic life[PMID:9579598]. During the course of phyletic evolution, one notes various changes. Indeed, in lower vertebrates, the SCO presents a greater degree of enzyme activity than the ependyma while in birds the ependyma demonstrates a more intense activity than the SCO[PMID:479574] Sometimes preceded by flexural organ[DOI:10.1007/BF00303086]. Hypendymal cells are rare in non-mammals [PMID:9579598]. |
