Sensory receptors tshwm sim hauv lub cev tshwj xeeb xws li cov qhov muag , pob ntseg , qhov ntswg, thiab qhov ncauj, nrog rau cov kabmob sab hauv. Txhua tus neeg txais tus qauv nthuav tawm qhov kev xav sib txawv los ua ke rau hauv ib qho kev nkag siab ib leeg zuj zus.
Ib yam li ntawd, nws tau nug, dab tsi yog 5 qhov kev hnov mob receptors?
Tsib qhov yooj yim ntawm qhov hnov qab tus neeg txais qhov kawg muaj nyob hauv tib neeg lub cev: thermoreceptors kuaj pom qhov hloov pauv ntawm qhov kub thiab txias; cov kws kho tsheb teb rau lub cev deformation; nociceptors teb rau qhov mob, photoreceptors / electromagnetic receptors yog qhov muag receptors ntawm retina; chemoreceptors pom ntxhiab, saj, sab hauv stimuli
Ib yam nkaus, qhov twg yog qhov kev hnov qab ntau tshaj plaws nyob? Sensors Receptors thiab Mechanotransduction Muaj ntau qhov kev hnov qab receptors yog nyob ntawm tus tsiaj txhawm rau txhawm rau txheeb xyuas qhov kev tawm tsam sab nraud, tab sis lwm tus dag hauv cov ntaub so ntswg hauv lub cev los saib xyuas cov haujlwm hauv nruab nrog cev thiab muab cov lus qhia tseem ceeb hauv homeostatic.
Hais txog qhov no, dab tsi yog qhov kev hnov qab receptors?
Sensors receptors yog cov hlwb tshwj xeeb, feem ntau yog neurons, uas kuaj thiab teb rau lub cev thiab tshuaj lom neeg. Feem ntau yog exquisitely rhiab heev rau cov tswv yim tshwj xeeb, los yog kev xav modalities, xws li txav mus los, tshuaj tsw qab los yog pom lub teeb photons.
Puas muaj cov neeg txais kev nkag siab hauv lub hlwb?
Cov kev xav lub paj hlwb yog ib feem ntawm lub paj hlwb lub luag haujlwm rau kev ua kev xav ntaub ntawv A kev xav system muaj kev xav neurons (nrog rau sensory receptor cell), txoj kev neural, thiab ib feem ntawm lub hlwb koom nrog kev xav kev xaav.

Cov kab mob tseem ceeb ntawm kev txhawj xeeb thaum tham txog cov txheej txheem cov kab mob hauv cov ntshav yog dab tsi?
Cov kab mob tseem ceeb ntawm kev txhawj xeeb yog tib neeg kev tiv thaiv kab mob tsis zoo (HIV), kab mob siab B (HBV), thiab kab mob siab C (HCV). Cov neeg ua haujlwm thiab cov tswv ntiav haujlwm yuav tsum ua kom muaj txiaj ntsig ntawm kev tswj hwm kev tsim vaj tsev thiab kev ua haujlwm txhawm rau tiv thaiv kom tsis txhob muaj ntshav thiab lwm yam kua hauv lub cev
Dab tsi ua kom muaj peev xwm ntawm cov kab mob pathogenic ua rau muaj kab mob?
Cov kab mob virulence pab cov kab mob kom (1) nkag mus rau tus tswv tsev, (2) ua rau muaj kab mob, thiab (3) zam tus tswv tsev tiv thaiv. Exotoxins: Exotoxins suav nrog ntau hom kab mob protein thiab cov enzymes tsim thiab/lossis zais los ntawm cov kab mob pathogenic. Cov pawg loj suav nrog cytotoxins, neurotoxins, thiab enterotoxins
Dab tsi yog 2 txoj hauv kev uas cov kab mob ua rau muaj kab mob?
Ob txoj hauv kev uas cov kab mob ua rau muaj kab mob yog los ntawm kev kis kab mob thiab tsim cov co toxins. Tus txheej txheem ntawm kis tus tswv tsev yog hu ua kev kis tus kabmob
Dab tsi yog cov kab mob thiab cov kab mob uas cuam tshuam rau cov kab mob integumentary?
Cov pob txuv cuam tshuam nrog qhov txhaws ntawm qhov pores, uas tuaj yeem ua rau muaj kab mob thiab mob, thiab feem ntau pom hauv cov tub ntxhais hluas. Lwm yam kab mob, tsis tau tham txog ntawm no, suav nrog seborrheic dermatitis (ntawm tawv taub hau), psoriasis, mob khaub thuas, impetigo, kab mob khaus, khaus khaus, thiab pob tw
Vim li cas thiaj sim tshuaj tiv thaiv kab mob rhiab rhiab?
Kev kuaj tshuaj tua kab mob rhiab heev (lossis susceptibility) yog ua los pab xaiv cov tshuaj tua kab mob uas yuav ua tau zoo tshaj plaws tiv thaiv cov kab mob tshwj xeeb lossis cov kab mob fungus kis rau ib tus neeg. Cov kab mob tshwm sim los ntawm cov kab mob tiv taus kab mob los yog cov kab mob tsis kho los ntawm kev kho nrog cov tshuaj tua kab mob no
