Definition of muscarinic in English:



  • Relating to a type of acetylcholine receptor in the nervous system which is capable of responding to muscarine.

    • ‘The central nervous system also contains muscarinic receptors.’
    • ‘Viral infection can cause dysfunction of M2 muscarinic receptors (of parasympathetic nerves) leading to increased release of acetylcholine and airway hyperreactivity.’
    • ‘The release of acetylcholine stimulates three types of muscarinic receptors, M1 - M3, to produce bronchoconstriction and mucous secretion.’
    • ‘Anticholinergics block muscarinic receptors on airway smooth muscle and possibly on submucosal gland cells.’
    • ‘As a result the drugs often cause side effects by affecting muscarinic receptors elsewhere, resulting in dry mouth or eyes, constipation, and, more rarely, headache or nausea.’
