Phenotype: somite has fewer parts of type muscle pioneer, abnormal
Note: This statement combines anatomy and/or ontology terms with phenotype quality terms to create a complete phenotype (EQ) statement. For detailed information on individual terms, click the hyperlinked term name.
Name: somite
Synonyms: somitic mesoderm
Definition: Undifferentiated mesodermal components of early trunk or tail segments or metameres, derived from paraxial mesoderm; forms myotomes, sclerotomes and perhaps dermatomes.
Ontology: Anatomy Ontology [ZFA:0000155]
Name: has fewer parts of type
Synonyms: decreased number of, has decreased number of, has fewer physical parts of type
Definition: The bearer of this quality has_part < n AND has_part > 0 of the indicated entity type, where n is the normal amount for a comparable organism. Note that the bearer of the quality is the whole, not the part. Formally: If a bearer entity e has fewer parts of type X at time t, then the number of instances x of X at t such that x part_of e is < n, where n is either the normal number for comparable entities, or n is stated explicitly.
Ontology: Phenotypic Quality Ontology [PATO:0002001]
Name: muscle pioneer
Synonyms: muscle pioneers, non migratory adaxial cells
Definition: Cells that develop from adaxial cells that express engrailed and do not migrate completely to the lateral surface of the myotome, and instead extend from the notochord to the lateral surface of the somite, at the level of the future horizontal myoseptum.
