| cholinergic agonists | Drugs that bind to and activate cholinergic receptors. (12 Dec 1998) |
|---|---|
| cholinergic antagonists | Drugs that bind to but do not activate cholinergic receptors, thereby blocking the actions of acetylcholine or cholinergic agonists. (12 Dec 1998) |
| cholinergic blockade | Inhibition by a drug of nerve impulse transmission at autonomic ganglionic synapses (ganglionic blockade), at postganglionic parasympathetic effector cells (e.g., by atropine), and at myoneural junctions (myoneural blockade), the inhibition of a cholinergic agent. (05 Mar 2000) |
| cholinergic fibres | Nerve fibres liberating acetylcholine at the synapse after an impulse. (12 Dec 1998) |
| cholinergic medication | <pharmacology> Medications which stimulate cholinergic receptors (for example bethanechol). (15 Jan 1998) |
| cholinergic neuron | <physiology> Neurons in which actylcholine is the neurotransmitter. (15 Jan 1998) |
| cholinergic parasympathomimetic agent | <pharmacology> A chemical substance that causes the release of choline (acetylcholine) from parasympathetic nerve endings. (15 Jan 1998) |
| cholinergic receptors | Chemical sites in effector cells or at synapses through which acetylcholine exerts its action. (05 Mar 2000) |
| cholinergic system | <physiology> The system of nerve cells that uses acetylcholine as its neurotransmitter, nerve cells in the cholinergic system are damaged in the brains of Alzheimer patients. (15 Jan 1998) |
| cholinergic urticaria | A form of physical or non-allergic urticaria initiated by heat (e.g., hot baths, physical exercise, pyrexia, exposure to sun or to a warm room) or by excitement; the rather distinctive lesions consist of pruritic areas 1 to 2 mm in diameter surrounded by bright red macules. Synonym: heat urticaria. (05 Mar 2000) |
| nicotinic cholinergic receptor | A class of receptors responsive to acetylcholine that also are activated by nicotine; ganglionic (including the adrenal medulla) and neuromuscular receptors. Two classes exist: nicotinic-neuronal and nicotinic-muscular. (05 Mar 2000) |
