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.

Accession:UBERON:0000040 term browser browse the term
Definition:A hemopoietic organ found in elasmobranchs. Along with the spleen and special tissue around the gonads, this structure produces red blood cells and it is nestled along the top and bottom of the esophagus.
Comment:Phenotype notes: Leydig's organ can be quite large - a 1.6-kilogram (3.5-pound) one was reported from a 1.8-metre (6-foot) long Bluntnose Sixgill Shark (Hexanchus griseus). Structure notes: divided into dorsal and ventral patches, gradation varies between species. Lacks erythroblasts and fat cells[Honma 1983]
Synonyms:xref: Wikipedia:Leydig's_organ
