Phenotype: dorsal aorta intersegmental vessel separated from dorsal longitudinal anastomotic vessel, 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: dorsal aorta
Synonyms: DA, dorsal aortic root
Definition: Principal unpaired, median artery of the trunk, leading from the paired roots (radices) of the dorsal aorta to the caudal artery.
Ontology: Anatomy Ontology [ZFA:0000014]
Name: intersegmental vessel
Synonyms: intersegmental vessels, intersomitic vessels, segmental vessel
Definition: Blood vessels that connect the dorsal aorta or the posterior cardinal vein and the dorsal longitudinal anastomotic vessel. They run along the vertical myotomal boundaries. At early stages these vessels don't have venous or arterial markers.
Ontology: Anatomy Ontology [ZFA:0001285]
Name: separated from
Synonyms: discontiguous, divided_from, splitted from
Definition: A structural quality inhering in a bearer by virtue of the bearer's not being in contact with another entity, or of no longer being connected or joined with another entity.
Ontology: Phenotypic Quality Ontology [PATO:0001505]
Name: dorsal longitudinal anastomotic vessel
Synonyms: DLAV
Definition: Paired trunk vessels that run medially along the dorsal-most portion of the trunk and post-vent region. The DLAVs are formed by the longitudinal anastomoses of the intersegmental vessels to form a right and left pair of dorsal longitudinal anastomotic vessels. These paired vessels remodel to form a single plexiform vessel beginning at 3dpf continuing until after 7dpf. The basilar artery connects to the DLAVs at the caudal end of the medulla oblongata. In the early embryo (2.5-3.5 dpf) the primitive hindbrain channels also connect to the DLAV.
