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 layer of cells produced during the process of gastrulation during the early development of the animal embryo, which is distinct from other such layers of cells, as an early step of cell differentiation. The three types of germ layers are the endoderm, ectoderm, and mesoderm.
Comment:Classically the germ layers are ectoderm, mesoderm and endoderm. Alternatively: primary = ectoderm, endoderm; secondary=mesoderm; tertiary=dorsal mesoderm, NC[https://github.com/obophenotype/uberon/wiki/The-neural-crest]
Synonyms:exact_synonym: germinal layer
 narrow_synonym: primary germ layer
 broad_synonym: embryonic tissue
 related_synonym: embryonic germ layer;   embryonic germ layers
