Name: heart primordium
Synonyms: cardiac field, heart primordia
Definition: Bilateral groups of cells consisting of three rows: one row of endocardial precursors medially and two rows of myocardial precursors laterally. The two populations fuse at the midline between 21 and 26 somites to form the heart rudiment or cone.
Ontology: Anatomy Ontology [ZFA:0000028]
Name: regulation of nodal signaling pathway
Synonyms: regulation of nodal signaling, regulation of nodal signalling pathway
Definition: Any process that modulates the frequency, rate or extent of nodal signaling pathway.
Ontology: GO: Biological Process [GO:1900107]    QuickGO    AmiGO
Name: decreased process quality
Synonyms:
Definition: A quality of a process that has a value that is decreased compared to normal or average.
Ontology: Phenotypic Quality Ontology [PATO:0002302]
