Acetylcholine is a potent neurotransmitter released from neurons. After release, it diffuses across the synaptic cleft and combines with nicotinic acetylcholine receptor molecules in the membrane of the postsynaptic cell. This interaction produces a large transient increase in the permeability of the membrane to specific ions, resulting in signal transduction. The nicotinic acetylcholine receptor is a:
