Accession:UBERON:0006257 term browser browse the term
Definition:A groove in the floor of the pharynx formed from the ventral diverticulum of endoderm that arises from the floor of the foregut caudal to the pharynx. This structure is the precursor for the larynx and trachea[WP,edited].
Comment:[homology-note] "Lung development begins with the appearance of the laryngotracheal groove, which is a small diverticulum that arises from the floor of the primitive pharynx at E9 in mouse and 4 wk in human.[well established][VHOG]" xsd:string {date_retrieved="2012-09-17", external_class="VHOG:0001404", ontology="VHOG", source="PMID:15817505 Warburton D, Bellusci S, De Langhe S, Del Moral PM, Fleury V, Mailleux A, Tefft D, Unbekandt M, Wang K, Shi W, Molecular mechanisms of early lung specification and branching morphogenesis.
