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: retina
Synonyms: retinas
Definition: Multi-tissue structure that contains the retinal neural layer and the retinal pigmented epithelium, and develops from the optic cup.
Ontology: Anatomy Ontology [ZFA:0000152]
Name: central region
Synonyms:
Definition: Anatomical region centrally located on the body or body part.
Ontology: Spatial Ontology [BSPO:0000075]
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: retinal rod cell
Synonyms: retinal rod cells
Definition: One of the two photoreceptor cell types of the vertebrate retina. In rods the photopigment is in stacks of membranous disks separate from the outer cell membrane. Rods are more sensitive to light than cones, but rod mediated vision has less spatial and temporal resolution than cone vision.
