Heart Myocytes
1 Stimulation from parasympathetic nervous system
1.1 Acetylcholine acts on metabotropic, muscarinic receptors in the heart
1.1.1 G-Protein is activated
1.1.1.1 Effector protein is a K+ ion channel (stimulated to open)
1.1.1.1.1 K+ ions flow out of the cell (down their concentration gradient)
1.1.1.1.1.1 Increases negativity inside the cell (hyperpolarisation)
1.1.1.1.1.1.1 Leads to decreased contraction
