Tsib hom kev hloov pauv loj xws li atrophy , hypertrophy , hyperplasia , dysplasia . 5. Atrophy yog qhov txo qis hauv cell loj.
Yog li ntawd, dab tsi yog hom loj ntawm kev hloov pauv ntawm tes?
Txheej txheem cej luam: The plaub yam yooj yim ntawm kev hloov pauv ntawm tes yuav tsum tau tham hauv ntu no yog hyperplasia, hypertrophy, atrophy, thiab metaplasia.
Ib yam li ntawd, cellular adaptation hypertrophy yog dab tsi? Thaum cell hypertrophy , cov khoom ntawm ntawm tes nce tus lej nrog kev muaj peev xwm ua haujlwm tau zoo rau kev sib tham tau nce ntawm tes xav tau. Hypertrophy feem ntau tshwm sim hauv cov xwm txheej uas lub cev lossis cov nqaij tsis tuaj yeem ua tau hloov kom muaj kev xav tau ntau ntxiv los ntawm kev tsim cov cell ntau.
Hauv qhov no, kev hloov pauv ntawm tes muab piv txwv yog dab tsi?
Cov kev hloov pauv no suav nrog hypertrophy (loj ntawm ib tus neeg lub hlwb), hyperplasia (nce ntawm cov xov tooj ntawm tes), atrophy (txo qhov loj thiab xov tooj ntawm tes), metaplasia (kev hloov ntawm ib hom epithelium mus rau lwm tus), thiab dysplasia (kev loj hlob ntawm cov hlwb).
Dab tsi yog qhov txawv ntawm physiological thiab pathological atrophy?
Atrophy yog tus general lub cev Cov txheej txheem ntawm reabsorption thiab tawg ntawm cov ntaub so ntswg, cuam tshuam nrog apoptosis. Thaum nws tshwm sim los ntawm cov kab mob los yog poob ntawm kev txhawb nqa trophic vim muaj lwm yam kab mob, nws yog hu ua pathological atrophy , txawm hais tias nws tuaj yeem yog ib feem ntawm lub cev kev loj hlob thiab homeostasis ib yam nkaus.

Kev sib raug zoo ntawm kev loj hlob ntawm tes thiab kev tsim tawm ntawm tes yog dab tsi?
Thaum lub sij hawm Binary fission thiab mitosis theej tawm cov DNA cov ntsiab lus ntawm kev tsim cov niam txiv ntawm tes tau muab cais ua ob qhov sib npaug sib luag uas yog lub hom phiaj kom xaus rau hauv ob tus ntxhais ntxhais. Ib feem kawg ntawm cov txheej txheem ntawm kev tsim cov cell yog faib cell, thaum tus ntxhais lub cev lub cev sib cais los ntawm niam txiv ntawm tes
Yam twg ntawm cov hauv qab no yog qhov hloov pauv hloov pauv tau rau kev mob pob txha?
Yam yuav hloov pauv tau yam muaj xws li: Dej cawv. Kev haus luam yeeb. Low Body Mass Index. Kev noj zaub mov tsis zoo. Vitamin D tsis txaus. Kev noj zaub mov tsis zoo. Estrogen tsis muaj peev xwm. Kev tawm dag zog tsis txaus
Kev sib raug zoo ntawm kev hloov pauv thiab kev nug txog mob qog noj ntshav yog dab tsi?
Mob qog noj ntshav yog kab mob uas cov cell faib tsis tau tswj hwm. Qee cov noob tsim cov qauv, qee cov txheej txheem tswj. Cancer tshwm sim los ntawm kev hloov pauv uas cuam tshuam kev sib txuas ntawm mitosis. Cells txuas ntxiv tsim cov qog nqaij hlav
Dab tsi yog ntu ntu ntawm theem ntawm kev hloov tus cwj pwm raws li theem ntawm kev hloov pauv qauv?
TTM tso siab tias tib neeg txav mus rau rau theem ntawm kev hloov pauv: kev npaj ua ntej, kev xav, kev npaj, kev nqis tes ua, kev saib xyuas, thiab txiav tawm. Kev txiav tawm tsis yog ib feem ntawm tus qauv qub thiab tsis tshua muaj siv nyob rau hauv daim ntawv thov ntawm theem ntawm kev hloov pauv rau kev coj cwj pwm kev noj qab haus huv
Kev hloov pauv hloov pauv yog dab tsi?
Kev hloov pauv hloov pauv hloov pauv ntawm cov khoom nruab nrog nruab nrab ntawm ob tsev neeg, uas tsis tuaj yeem pub khoom nruab nrog cev rau lawv tsev neeg vim yog pawg ntshav tsis sib haum. Qhov no yog nyob rau hauv kev nkag siab 'khub pauv'
