CROSS-SPECIES ANATOMY - ANNOTATIONS

The Basic subset of the UBERON integrated, cross-species anatomy ontology is downloaded weekly from http://berkeleybop.org/ontologies/uberon/basic.obo. For more information about this ontology see the "About" page on the UBERON website at http://uberon.github.io/about.html.

Definition:In mammals, the pronephros is the first of the three embryonic kidneys to be established and exists only transiently. In lower vertebrates such as fish and amphibia, the pronephros is the fully functional embryonic kidney and is indispensible for larval life[GO].
Comment:Once the more complex mesonephros forms the pronephros undergoes apoptosis in amphibians. In fishes the nephron degenerates but the organ remains and becomes a component of the immune system[Wikipedia:Pronephros]. // TODO - check developmental relationships. Note that we previously include the ZFA/XAO terms under the more specific 'pronephric kidney', but these are now merged. TODO GCI: relationship: capable_of GO:0030104; [homology-note] "In all vertebrate embryos, the kidney begins with the differentiation of a few renal tubules from the anterior end of the nephric ridge overlying the pericardial cavity. (...) This early-developing embryonic kidney is called the pronephros.[well established][VHOG]" xsd:string {date_retrieved="2012-09-17", external_class="VHOG:0000037", ontology="VHOG", source="ISBN:978-0030223693 Liem KF, Bemis WE, Walker WF, Grande L, Functional Anatomy of the Vertebrates: An Evolutionary Perspective (2001) p.637", source="http://bgee.unil.ch/"}
