Gi Muscarinic Cardiac Muscle Contraction
smpdb.ca/view/SMP0126951PhysiologicalThe M2 muscarinic receptors are located in the heart, where they act to slow the heart rate down to normal sinus rhythm after negative stimulatory actions of the parasympathetic nervous system, by slowing the speed of depolarization. The...
