Phenotype: VaP motor neuron axon protruding into 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: VaP motor neuron
Synonyms: variable primary motoneuron
Definition: A primary motor neuron of the spinal cord. This cell is present in slightly less than half of the trunk hemisegments. Additionally, this cell has at least 2 different fates: it may become a primary motoneuron and arborize in an exclusive muscle territory, or it may die during embryonic development.
Ontology: Anatomy Ontology [ZFA:0005181]
Name: axon
Synonyms:
Definition: The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter.
Ontology: GO: Cellular Component [GO:0030424]    QuickGO    AmiGO
Name: protruding into
Synonyms:
Definition: A quality inhering into a bearer by virtue of the bearer's extending out above or beyond its surface or boundary into the surface or boundary of another entity.
Ontology: Phenotypic Quality Ontology [PATO:0001645]
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.
