cholinergic receptors(redirected from cholinoreceptors)
chemical sites in effector cells or at synapses through which acetylcholine exerts its action.
cho·lin·er·gic re·cep·tors(kō'lin-ĕr'jik rĕ-sep'tŏrz)
Chemical sites in effector cells or at synapses through which acetylcholine exerts its action.
1. parasympathomimetic; activated or transmitted by acetylcholine; said of nerve fibers that liberate acetylcholine at a synapse when a nerve impulse passes, i.e. the parasympathetic fibers.
2. an agent that resembles acetylcholine or simulates its action.
selective inhibition of cholinergic nerve impulses at autonomic ganglionic synapses, postganglionic parasympathetic effectors, or neuromuscular junctions.
that form of neurotransmission which depends on the production of acetylcholine at synapses.
receptor sites on effector organs or at nerve synapses that are stimulated by acetylcholine released by the nerve terminal. There are two types: muscarinic receptors, present primarily on autonomic effector cells, and nicotinic receptors, present primarily on autonomic ganglion cells and on the motor end plates of skeletal muscle.
