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: optic tectum
Synonyms: dorsal midbrain, mesencephalic tectum, tectal lobe, tectum, tectum opticum
Definition: Multi-tissue structure that is the dorsal part of the midbrain and develops from the alar plate and is the most complex layered structure in the zebrafish brain.
Ontology: Anatomy Ontology [ZFA:0000445]
Name: lacks parts or has fewer parts of type
Synonyms: loss of
Definition: The bearer of this quality has_part < n 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. This case includes the limit case, where the bearer lacks all parts of the specified type.
Ontology: Phenotypic Quality Ontology [PATO:0001999]
Name: microglial cell
Synonyms: microglia
Definition: A central nervous system macrophage found in the parenchyma of the central nervous system.
Ontology: Anatomy Ontology [ZFA:0009077]
