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

Informações
- Descrição
- An example of a Direct- Effector Linked Pathway in Heart Myocytes. Note: The same neurotransmitter (acetylcholine) causes the opposite effect in skeletal muscle.
