uberon_slim, efo_slim, organ_slim
Organ with organ cavity which is continuous proximally with the cecum and distally terminates in the tip of the appendix. Examples: There is only one appendix[FMA:14542].
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]
