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:A cranial placode which, once specified, invaginates to form an otic cup, which eventually separates from the surface ectoderm to form the otic vesicle or otocyst, a rounded structure without appar- ent polarity. As the otic placode invaginates into a cup neuroblasts delaminate from the anterior ventral aspect of the otic epithelium to give rise to neurons of the vestibulocochlear (statoacoustic) ganglion of cranial nerve VIII[NBK].
Comment:[development-note] "With the exception of the pigment cells of the stria vascularis and the secretory epithelium of the cochlea, which are of neural crest origin, all compo- nents of the inner ear derive from the otic placode. In most species the thickening of the ectoderm into a placode occurs in a region adjacent to rhombomere 5 (reviewed in Ohyama et al., 2007), while in amphibians the otic placode is centered onto rhombomere 4 (Ruiz i Altaba and Jessell, 1991)." xsd:string {source="NCBIBook:NBK53175"}; [homology-note] "We conclude this section by listing some of the many synapomorphies of craniates, including (...) (2) neurogenic placodes (...).[well established][VHOG]" xsd:string {date_retrieved="2012-09-17", external_class="VHOG:0000235", ontology="VHOG", source="ISBN:978-0030223693 Liem KF, Bemis WE, Walker WF, Grande L, Functional Anatomy of the Vertebrates: An Evolutionary Perspective (2001) p.43", source="http://bgee.unil.ch/"}
