Structures of muscarinic ligands. … WebThe parasympathetic nervous system of the respiratory tract is involved in the control of airway calibre in three ways: through afferent nerve pathways (pulmonary reflexes); through efferent nerve pathways (reflexes, interaction between efferent vagus and mediators or modulating transmitter substances) and through cholinergic muscarinic receptors and …
WebCholinergic activators are agonists that stimulate cholinergic receptors resulting in stimulation of the parasympathetic nervous system (rest and digest). Similar to adrenergic receptors, cholinergic rectors are located on a variety of organs that also have predictable responses based on the receptor type that is stimulated. WebThere are two broad classes of cholinergic receptors: nicotinic and muscarinic. This classification is based on two chemical agents that mimic the effects of ACh at the receptor site nicotine and muscarine. Table I summarizes some of the properties of nicotinic and muscarinic receptors. 11.10 The Nicotinic Receptor is an Ion Channel Figure 11.8
