acute phase response  a group of physiological processes occurring soon after the onset of infection, trauma, inflammatory processes, and some malignant conditions; it includes increase in acute phase proteins in serum, fever, increased vascular permeability, and metabolic and pathologic changes.

anamnestic response  secondary immune r.

autoimmune response  the immune response against an autoantigen.

conditioned response  a response evoked by a conditioned stimulus; a response to a stimulus that was incapable of evoking it before conditioning.

galvanic skin response  the alteration in the electrical resistance of the skin associated with sympathetic nerve discharge.

immune response  any response of the immune system to an antigenic stimulus, including antibody production, cell-mediated immunity, and immunological tolerance.

primary immune response  the immune response occurring on the first exposure to an antigen, with specific antibodies appearing in the blood after a multiple day latent period.

relaxation response  a group of physiologic changes that cause decreased activity of the sympathetic nervous system and consequent relaxation after stimulation of certain regions of the hypothalamus. They may be self-induced through techniques such as meditation and biofeedback.

secondary immune response  the immune response occurring on second and subsequent exposures to an antigen, with a stronger response to a lesser amount of antigen, and a shorter lag time compared to the primary immune response.

triple response (of Lewis)  a triphasic skin reaction to being stroked with a blunt instrument: first a red line develops at the site due to histamine release, then a flare develops around the red line, and lastly a wheal is formed as a result of local edema.

unconditioned response  an unlearned response, i.e., one that occurs naturally to an unconditioned stimulus.

response [re-spons´]

any action or change of condition evoked by a stimulus.

acute phase response a group of physiologic processes occurring soon after the onset of infection, trauma, inflammatory processes, and some malignant conditions. The most prominent change is a dramatic increase of acute phase proteins in the serum, especially C-reactive protein. Also seen are fever, increased vascular permeability, and a variety of metabolic and pathologic changes.

anamnestic response the rapid reappearance of antibody in the blood following introduction of an antigen to which the subject had previously developed a primary immune response.

auditory brainstem response ABR; a special hearing test that tracks the nerve signals arising in the inner ear as they travel along the auditory nerve to the brain region responsible for hearing. A small speaker placed near the ear makes a clicking sound, and special electrodes record the nerve signal as it travels. The test can determine where along the nerve there is a lesion responsible for sensorineural hearing loss. It is often used for individuals with such loss in just one ear; this is often caused by a benign tumor along the auditory nerve, but if the ABR reading is normal in a given region, the chances of there being a tumor there are small. This test can also be used on infants since it requires no conscious response from the person being tested.

autoimmune response the immune response in which antibodies or immune lymphoid cells are produced against the body's own tissues. See also autoimmune disease.

conditioned response see conditioned response.

dysfunctional ventilatory weaning response a nursing diagnosis adopted by the North American Nursing Diagnosis Association, defined as inability of a patient to adjust to lowered levels of mechanical ventilator support, which interrupts and prolongs the process of weaning. See also mechanical ventilatory weaning.

galvanic skin response the alteration in the electrical resistance of the skin associated with sympathetic nerve discharge.

immune response see immune response.

inflammatory response the various changes that tissue undergoes when it becomes inflamed; see inflammation.

post-trauma response former name for the nursing diagnosis post-trauma syndrome.

reticulocyte response increase in the formation of reticulocytes in response to a bone marrow stimulus.

triple response (of Lewis) a physiologic reaction of the skin to stroking with a blunt instrument: first a red line develops at the site of stroking, owing to the release of histamine or a histamine-like substance, then a flare develops around the red line, and lastly a wheal is formed as a result of local edema.

unconditioned response an unlearned response, i.e., one that occurs naturally, in contrast to a conditioned response.

autoimmune response

the immune response in which antibodies or immune lymphoid cells are produced against the body's own tissues.

conditioned response

see also conditioned response, conditioning.

dazzle response

shining a bright light in the eye causes a blink. Called also dazzle reflex.

galvanic skin response

the alteration in the electrical resistance of the skin associated with sympathetic nerve discharge.

immune response

specifically altered reactivity of the animal body after exposure to antigen, manifested as antibody-production, cell-mediated immunity, development of hypersensitivity, or as immunological tolerance. Called also immune reaction. See also immune response.

maze response

a test of vision for animals.

placing response

see placing reflex.

response rate

in surveys, the number of completed survey instruments (questionnaires, interview records) divided by the total number of persons approached.

response trial

a field trial conducted to test a hypothesis, often about the cause of a disease but can encompass therapeutics or control of a disease. The hypothesis is tested by observing the response to an alteration in the system, e.g. in feeding or in management.

triple response (of Lewis)

a physiological reaction of the skin to stroking with a blunt instrument: first a red line develops at the site of stroking, owing to the release of histamine or a histamine-like substance, then a flare develops around the red line, and lastly a wheal is formed as a result of local edema.

unconditioned response

an unlearned response, i.e. one that occurs naturally. See also conditioning.
