muscarinic

pertaining to the transmission of nerve impulses mediated by muscarinic receptors; these may be adrenergic or cholinergic.

---

muscarinic activity

includes slowing and reduced stroke volume of the heart, bronchiolar constriction, arteriolar dilatation, increased tone, motility and secretion in the alimentary tract, and increases in salivation and lacrimation.

muscarinic blocking agents

block muscarinic receptors, e.g. atropine and the synthetic agents homatropine, methantheline, propantheline and methylatropine.

muscarinic receptors

cholinergic receptors of autonomic effector cells (and also on some autonomic ganglion cells and some central neurons) that are stimulated by muscarine and parasympathomimetic drugs and antagonized by atropine.
