WebCholinergic receptors bind Ach: Ach binds to two classes of receptors— nicotinic and muscarinic named for the drugs that were used to identify and distinguish them. Nicotine binds only to the former while muscarine (a mushroom poison) binds only to the other. When Ach binds to a nicotinic receptor it produces an excitatory postsynaptic potential. WebLong-acting anticholinergics are used in the treatment of chronic obstructive pulmonary disease (COPD) to produce bronchodilation. As you know from Chapter 6, activation … WebThe nicotinic-receptor antagonists that act at the neuromuscular junction are used during surgical procedures to produce muscle relaxation. Acetylcholine is inactivated by the enzyme acetylcholinesterase, which is located at cholinergic synapses and breaks down the acetylcholine molecule into choline and acetate. kevin leach attorney
