VERTEBRATE TRAIT ONTOLOGY - ANNOTATIONS

The Vertebrate Trait Ontology (VT) is being developed as a collaborative effort between the Rat Genome Database at the Medical College of Wisconsin (RGD, http://rgd.mcw.edu), Mouse Genome Informatics at the Jackson Laboratory (http://www.informatics.jax.org/) and the Animal QTL database at Iowa State University (http://www.animalgenome.org/cgi-bin/QTLdb/index). For more information about this vocabulary, or to request additions or changes, please contact us (http://rgd.mcw.edu/contact/index.shtml).

Definition:Any measurable or observable characteristic related to the physical magnitude of the irregularly shaped cavity in the rhombencephalon, between the medulla oblongata, the pons, and the isthmus in front, and the cerebellum behind; it is continuous with the central canal of the cord below and with the cerebral aqueduct above, and through its lateral and median apertures it communicates with the subarachnoid space.
Synonyms:exact_synonym: ventricle of rhombencephalon size trait;   ventriculus quartus size trait
