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.

Accession:MP:0030535 term browser browse the term
Definition:any structural anomaly of the condensed mesenchymal band formed as migratory myoblasts arising from the myotomes of the occipital somites coalesce beside somite four and extend ventrally as an elongated column; the hypoglossal cord eventually becomes located ventral to the caudal region of the pharynx; most of the myoblasts of the hypoglossal cord remain ventral and shift cranially to form the intrinsic and extrinsic tongue muscles; some of these myoblasts shift dorsally to form the intrinsic laryngeal muscles
