        Parasympathetic/cholinergic - muscarinic and nicotinic receptors
        
        Cholinergic drugs promote action of neurotransmitter acetylcholine/ called parasympathomimetic - imitate parasympathetic nerve stimulation
        
        cholinergic blocking drugs - / anticholinergic drugs - interrupt parasympathetic nerve impulses - prevent acetylcholine from stimulating cholinergic receptors

        sympathetic/adrenergic receptors - alpha - beta1, beta2
        
        Sympathomimetic drugs are agents which in general mimic responses due to stimulation of sympathetic nerves. These agents are able to directly activate adrenergic receptors or to indirectly activate them by increasing norepinephrine and epinephrine (mediators of the sympathoadrenal system) levels
