| neuromuscular depolarising agents | Drugs that interrupt transmission at the skeletal neuromuscular junction by causing sustained depolarisation of the motor end plate. These agents are primarily used as adjuvants in surgical anaesthesia to cause skeletal muscle relaxation. (12 Dec 1998) |
|---|---|
| neuromuscular junction | A chemical synapse between a motoneuron and a muscle fibre. Synonym: motor end plate. (18 Nov 1997) |
| neuromuscular nondepolarising agents | Drugs that interrupt transmission at the skeletal neuromuscular junction without causing depolarisation of the motor end plate. They prevent acetylcholine from triggering muscle contraction and are used as muscle relaxants during electroshock treatments, in convulsive states, and as anaesthesia adjuvants. (12 Dec 1998) |
| neuromuscular relaxant | An agent, e.g., curare or succinylcholine, that produces relaxation of striated muscle by interruption of transmission of nervous impulses at the myoneural junction. (05 Mar 2000) |
| neuromuscular spindle | A fusiform end organ in skeletal muscle in which afferent and a few efferent nerve fibres terminate; it contains from 3 to 10 striated muscle fibres (intrafusal fibres) that are much smaller than the ordinary muscle fibres, are separated from them by a capsule that encloses the organ, and are innervated by the thin axon of a gamma motoneuron (gamma motor fibre); the sensory endings that occur on the intrafusal fibres are either annulospiral or flower spray endings; this sensory end organ is particularly sensitive to passive stretch of the muscle in which it is enclosed. Synonym: Kuhne's spindle, muscle spindle. (05 Mar 2000) |
| neuromuscular system | The muscles of the body collectively and the nerves supplying them. (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) |
| Rh blocking test | A test for nonagglutinating Rh antibodies: an Rh agglutination test is first carried out; if the test for Rh agglutinins is negative, then 1 drop of anti-Rho agglutinating serum of moderate titre is mixed with the patient's serum containing Rh-positive test cells; if after incubating for from 1 to 2 hr at 37캜 no agglutination occurs, Rho-blocking antibodies are assumed to be present in the patient's serum. (05 Mar 2000) |
| spermatogenesis-blocking agents | Chemical substances which inhibit the process of spermatozoa formation at either the first stage, in which spermatogonia develop into spermatocytes and then into spermatids, or the second stage, in which spermatids transform into spermatozoa. (12 Dec 1998) |
| agent | <pharmacology> Any power, principle or substance capable of producing an effect, whether physical, chemical or biological. Origin: L. Agens = acting (18 Nov 1997) |
| agent, antihypertensive | As the name suggests, a drug aimed at reducing high blood pressure (hypertension). (12 Dec 1998) |
