WebThis reduces overall choline uptake)-Triethycholine (mimics choline, and causes failure of cholinergic transmission by interfering with synthesis of acetylcholine in nerve ending. It does this because it binds to choline uptake carriers and this time can be taken up by the carrier unlike, hemicholinium, and it follows the same pathway as ... WebCholinergic blockers usually inhibit cholinergic nerve transmission at the neuroeffector junction, or the point where the nerve ending reaches the effector organs such as smooth muscle, cardiac muscle, and glands. Cholinergic blockers have little effect at the nicotinic receptors, although at high doses they can have partial blocking effects.
