Name: fourth ventricle
Synonyms: 4th ventricle, hindbrain ventricle, rhombencephalic ventricle, rhombencephalic vesicle, ventricle IV, ventriculus rhombencephali
Definition: Fluid-filled brain cavity. Most posterior brain ventricle.
Ontology: Anatomy Ontology [ZFA:0000110]
Name: apical side
Synonyms: apical
Definition: Anatomical side that is located on the apical end of an organism or structure.
Ontology: Spatial Ontology [BSPO:0000057]
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: cilium
Synonyms: eukaryotic flagellum, flagellum, microtubule-based flagellum
Definition: A specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface and of some cytoplasmic parts. Each cilium is largely bounded by an extrusion of the cytoplasmic (plasma) membrane, and contains a regular longitudinal array of microtubules, anchored to a basal body.
