Term:cell-cell signaling involved in cardiac conduction
go back to main search page
Accession:GO:0086019 term browser browse the term
Definition:Any process that mediates the transfer of information from one cell to another and contributes to the heart process that regulates cardiac muscle contraction; beginning with the generation of an action potential in the sinoatrial node and ending with regulation of contraction of the myocardium.
Synonyms:exact_synonym: cell-cell signalling involved in cardiac conduction
