Examples: There is only one appendix[FMA:14542]. appendix vermiformis NCIT:C12380 EMAPA:35140 apex of caecum appendiceal GAID:308 A blind-ended tube connected to the cecum, from which it develops embryologically[WP]. apex of cecum EHDAA2:0000588 FMA:14542 caecal appendix EV:0100080 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] appendix vermiformis MAT:0000287 appendix EV:0100076 MA:0001540 Wikipedia:Vermiform_appendix MESH:D001065 UBERON:0001154 VHOG:0001306 CALOHA:TS-1267 EFO:0000849 SCTID:181255000 UMLS:C0003617 digestive system element
