Acetylcholine binds to receptors on the postsynaptic cell membrane, the smooth muscle ends plates, and secretory glands, causing the muscarinic effects of acetylcholine. These effects include bronchospasm, low pulmonary compliance, nausea, vomiting, diarrhea, miosis, blurred vision, bradycardia, and hypersecretions of the oropharynx, conjunctivae, tracheobronchial tree, and gastrointestinal tract. Acetylcholine also binds to skeletal muscle end plates and synaptic ganglia, causing nicotinic effects. The nicotinic effects of acetylcholine include fasciculations, flaccid paralysis, tachycardia, and hypertension.
