Definition:A blind-ended tube connected to the cecum, from which it develops embryologically[WP].
Comment:[homology-note] "A comparative anatomical approach reveals three apparent morphotypes of the cecal appendix, as well as appendix-like structures in some species that lack a true cecal appendix. Cladistic analyses indicate that the appendix has evolved independently at least twice (at least once in diprotodont marsupials and at least once in Euarchontoglires), shows a highly significant (P < 0.0001) phylogenetic signal in its distribution, and has been maintained in mammalian evolution for 80 million years or longer.[well established][VHOG]" xsd:string {date_retrieved="2012-09-17", external_class="VHOG:0001306", ontology="VHOG", source="DOI:10.1111/j.1420-9101.2009.01809.x Smith HF, Fisher RE, Everett ML, Thomas AD, Randal Bollinger R, Parker W, Comparative anatomy and phylogenetic distribution of the mammalian cecal appendix.
