| 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 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) |
| alpha blocking | The attenuation of the occipital alpha rhythm (8-14 Hz brain waves as seen on an electroencephalogram), produced by opening the eyes or by intense mental concentration. (05 Mar 2000) |
| antibodies, blocking | Antibodies that inhibit the reaction between antigen and other antibodies or sensitised T-lymphocytes (e.g., antibodies of the IgG class that compete with IgE antibodies for antigen, thereby blocking an allergic response). Blocking antibodies that bind tumours and prevent destruction of tumour cells by cytotoxic T-lymphocytes have also been called enhancing antibodies. (12 Dec 1998) |
| blocking | 1. Obstructing; arresting of passage, conduction, or transmission. 2. In psychoanalysis, a sudden break in free association occurring when a painful subject or repressed complex is touched. 3. Sudden cessation of thoughts and speech, which may indicate the presence of a severe thought disorder or a psychosis. (05 Mar 2000) |
| blocking activity | The repression or elimination of electrical activity in the brain by the arrival of a sensory stimulus. (05 Mar 2000) |
| blocking antibody | An antibody used in a reaction to prevent some other reaction taking place, for example one antibody competing with another for a cell surface receptor. See: desensitisation. (18 Nov 1997) |
