go back to main search page
Accession:GO:0086046 term browser browse the term
Definition:The process in which SA node cardiac muscle cell membrane potential changes in the depolarizing direction from the negative resting potential towards the positive membrane potential that will be the peak of the action potential.
Synonyms:exact_synonym: membrane depolarization involved in regulation of SA node cardiac muscle cell action potential;   membrane depolarization involved in regulation of SAN cardiac muscle cell action potential;   membrane depolarization involved in regulation of sinoatrial node cardiac muscle cell action potential
 narrow_synonym: membrane depolarization involved in regulation of sinus node cardiac muscle cell action potential
