| nocardiaceae | A family of gram-positive, aerobic actinomycetes found in soil and animal tissue. Some species are the cause of infection in man and animals. (12 Dec 1998) |
|---|---|
| nocardiasis | <disease> Infection by any species of the bacteria Nocardia. Often affects the lungs and may be confused with tuberculosis. (27 Sep 1997) |
| nocardioform | Denoting an organism that morphologically and culturally resembles members of the genus Nocardia. (05 Mar 2000) |
| nocardioform group | A group of actinomycetes that forms mycelia that break up into rod-shaped or coccoid elements. Certain genera in this group are pathogenic to man. (12 Dec 1998) |
| nocardiosis | <disease> Infection by any species of the bacteria Nocardia. Often affects the lungs and may be confused with tuberculosis. (27 Sep 1997) |
| noci- | Hurt, pain, injury. Origin: L. Noceo (05 Mar 2000) |
| noci-influence | Injurious or harmful influence. (05 Mar 2000) |
| nociceptive | <physiology> The process of pain transmission, usually relating to a receptive neuron for painful sensations. (16 Dec 1997) |
| nociceptive reflex | Flexion of ankle, knee, and hip when the foot is painfully stimulated; the crossed extension reflex occurs in association with it. Synonym: defense reflex, nociceptive reflex, withdrawal reflex. (05 Mar 2000) |
| nociceptor | A peripheral nerve organ or mechanism for the reception and transmission of painful or injurious stimuli. Origin: noci-+ L. Capio, to take (05 Mar 2000) |
| nociceptors | Peripheral receptors for pain. Nociceptors include receptors which are sensitive to painful mechanical stimuli, extreme heat or cold, and chemical stimuli. All nociceptors are free nerve endings. (12 Dec 1998) |
| nocifensor | Denoting processes or mechanisms that act to protect the body from injury; specifically, a system of nerves in the skin and mucous membranes that react to adjacent injury by causing vasodilation. Origin: noci-+ L. Fendo (only in compounds), to strike, ward off (05 Mar 2000) |
| nocifensor reflex | Vascular dilation in a part surrounding an injury or in its neighborhood. (05 Mar 2000) |
| nociperception | The appreciation of injurious influences, referring to nerve centres. Origin: noci-+ perception (05 Mar 2000) |
| nocodazole | <chemical> (5-(2-thienylcarbonyl) 1h-benzimidazol-2-yl)carbamic acid methyl ester. Nocodazole is an antineoplastic agent which exerts its effect by depolymerizing microtubules. Pharmacological action: antineoplastic agent. Chemical name: Carbamic acid, (5-(2-thienylcarbonyl)-1H-benzimidazol-2-yl)-, methyl ester (12 Dec 1998) |
