Does the heart have acetylcholine receptors?
Does the heart have acetylcholine receptors? All regions of the mammalian heart are innervated by parasympathetic (vagal) nerves, although the supraventricular tissues are more densely innervated than the ventricles. Vagal activation causes stimulation of cardiac muscarinic acetylcholine receptors (M-ChR) that modulate pacemaker activity via I(f) and I(K. Where does acetylcholine bind to receptors? Acetylcholine binds […]
