Phenotype: optic tectum has fewer parts of type retinal ganglion cell axon, 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: 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: 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: retinal ganglion cell
Synonyms: gangliocyte, RGC
Definition: The set of neurons that receives neural inputs via bipolar, horizontal and amacrine cells. The axons of these cells make up the optic nerve.
Ontology: Anatomy Ontology [ZFA:0009310]
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.
