Sensitization - nws ... Nyob rau hauv peb lub ntsiab ntawm lub tib lub sij hawm

Sensitization phenomena cai nyob rau hauv biology, tshuaj, psychology, Science News for KIDS thiab physics, raws li zoo li ob peb lwm qhov chaw ntawm science. Nyob rau hauv cov ntaub ntawv no, lub sij hawm yog hais txog kev sib txawv heev yam. Yuav ua li cas koj txhais li cas?

Biology thiab tshuaj

Feem ntau, qhov no lub sij hawm yog siv allergists. Nyob rau hauv cov cheeb tsam no, sensitization - yog nce rau hauv lub cev rhiab heev rau tej sab nraud los yog sab hauv stimuli. Nws yog tus thawj theem ntawm kev tsis haum tshuaj nyob rau hauv cov lus teb rau hu nrog tej yam tshuaj. Nyob rau hauv cov ntaub ntawv no, lub cev ua tej antibodies, nce cov qog ntshav hauv, tus xov tooj ntawm lymphocytes, raws li zoo raws li lub cai hloov nyob rau hauv lub paj hlwb. Yog li, sensitization - yog, nyob rau hauv qhov tseeb, tus tsim ntawm ib tug tsis haum cov tshuaj tiv thaiv. Lub sij hawm tom qab kev sib cuag nrog lub irritant yuav tig mus rau hauv tag nrho-fledged teeb meem twb.

Muaj xws li ib tug tshaj plaws li v sensitization. Qhov no yog tib yam tshwm sim, tab sis cov kev xwm. Txij li thaum tej zaum nws yuav pom me ntsis cev xeeb tub cov poj niam nrog v-tsis zoo. Nyob rau hauv cov ntaub ntawv no protrude irritant cov nqaijrog nyob rau hauv me nyuam hauv plab ntshav.

Nyob rau hauv tas li ntawd, qhov no lub sij hawm nrog rau lub tswvyim ntawm "adaptation" kuj yog siv nyob rau hauv qhov kev piav qhia ntawm qhov txhia. Receptors yuav tau kawm, txoj kev xyaum lawv rhiab heev. Piv txwv li, txoj kev loj hlob ntawm saj thiab tsis hnov tsw yog koom tasters perfumers. Koj yuav tau qhia lub zeem muag los yog lub rooj sib hais, raising nws zuag qhia tag nrho nyhav los yog lo lus teb rau tej stimuli. Yog hais tias rau ib co yog vim li cas ib hom ntawm receptors tsis ua hauj lwm muaj xws li nyiaj them mechanisms, nce rhiab heev rau lwm yam kabmob. Yog li, sensitization - ib tug mechanism uas tso cai rau lub cev kom hloov mus rau tus tshiab tej yam kev mob, raws li tau zoo raws li lub teeb liab lub xub ntiag ntawm ib tug muaj zog stimulus.

Nyob rau hauv psychology

Tsis tsuas yog rau biologists thiab cov kws kho mob siv cov sij hawm no. Psychologists kuj siv cov tswvyim no rau hauv lawv cov chaw ua hauj lwm, kev totaub txog lawv tshwm sim ntawm cov tib yam, tab sis nyob rau lwm theem. Feem ntau, nws yog tseem ib lo lus nug ntawm desensitization, piv txwv li mitigating ntxhov siab vim tshua nyob hauv cov lus teb rau stimuli. Feem ntau, lub sij hawm siv nyob rau hauv lub ntsiab lus teb ntawm tau txais tshem ntawm phobias.

Lwm cheeb tsam ntawm daim ntawv thov - addicted rau ntau yam tshuaj. Nyob rau hauv qhov ntsiab lus teb, sensitization - ib tug ntau tsausmuag cov tshuaj tiv thaiv ntawm tus kab mob nyob rau hauv cov lus teb rau tus ua koob ntawm cov thawj. Ntawm no psychology yog twb zoo bordered los ntawm neurobiology, vim hais tias, raws li kev tshawb fawb, qhov no tshwm sim tshwm sim vim cov kev hloov nyob rau hauv lub thiaj li hu ua Library chaw. Nws yog dav paub lub tswvyim ntawm tus yees raws li tau cov nyhuv tib yam yuav tsum tau tag nrho cov ntau dua koob tshuaj. Nyob rau hauv qhov ntsiab lus teb, rov qab ntawm nws yog cia li sensitization.

Piv txwv ntawm kev siv ntawm lub sij hawm nyob rau hauv lwm yam kev teb

Cov tswvyim no kuj yog siv nyob rau hauv physics thiab, piv txwv li, nyob rau hauv photochemistry. Nyob rau hauv thawj cov ntaub ntawv, ib tug sensitization hais txog cov kev hloov ntawm lub zog los ntawm ib tug qauv rau lwm tus. Nyob rau hauv lub thib ob tham txog ua lub rhiab heev ntawm lub photographic khoom, thiab kuj cia cov spectral sensitization los ntawm txoj kev uas cov tshuaj tiv thaiv yog tiav xwb nyob rau hauv lub teeb ntawm ib tug tej yam wavelength.
