Like smooth muscle, cardiac muscle has muscarinic receptors. The effect of acetylcholine on cardiac muscle, however, is very different from its effects on skeletal or smooth muscle.In the heart, acetylcholine activation of muscarinic receptors causes channels in the muscle membrane to let potassium pass.This has the effect of slowing contraction of the heart muscle and making it beat with less force.cetylcholineâs Effect On Smooth Muscle.

When this receptor binds acetylcholine, one result is the release of calcium ions from internal stores.
