MAMMALIAN PHENOTYPE - ANNOTATIONS

The Mouse Adult Gross Anatomy Ontology and Mammalian Phenotype Ontology are downloaded weekly from the Mouse Genome Informatics databases at Jackson Laboratories (ftp://ftp.informatics.jax.org/pub/reports/index.html). For more information about these ontologies, see the MGI Publications Page at http://www.informatics.jax.org/mgihome/other/publications.shtml.

Term:abnormal primitive node morphology

Accession:MP:0004066 term browser browse the term
Definition:any structural anomaly of the regional thickening of cells at the rostral tip of the vertebrate primitive streak through which gastrulating cells migrate anteriorly to form tissues in the future head and neck; this region organizes the formation of the three embryonic layers and establishes the longitudinal axis and the polarity of the embryo
Synonyms:exact_synonym: abnormal embryonic node morphology;   abnormal primitive knot morphology;   abnormal prochordal knot morphology
 related_synonym: abnormal Hensen's node morphology;   abnormal Henson's node morphology;   abnormal Spemann's organizer morphology
