Hypertrophy yog ib txoj hauv kev loj hlob ntawm cov hlwb kom hloov mus rau kev hloov pauv hauv lawv ib puag ncig. Qhov no tuaj yeem yog qhov zoo thiab qhov tsis zoo. Hypertrophied txhais li cas? Qhov no yog, ntawm qhov tseeb ntawm lo lus, raug rau hypertrophy.
Definition of hypertrophy
Lo lus yog siv los piav txog ib txoj hauv kev uas cov hlwb (cov me me uas ua haujlwm tseem ceeb hauv peb lub cev) hloov mus rau ib puag ncig kev hloov pauv. Nws tuaj yeem yog hormonal stimulation, o, lossis ua haujlwm ntau ntxiv.
Yuav kom lawv noj qab nyob zoo, ib puag ncig uas muaj cov khoom siv hauv tsev zoo li no yuav tsum muaj kev noj qab haus huv, thiab cov haujlwm uas lawv yuav tsum ua yuav tsum nyob hauv ib txwm txwv. Yog tias muaj kev hloov pauv tseem ceeb hauv ib puag ncig, cov hlwb yuav sim hloov mus rau qhov xwm txheej kom muaj peev xwm ua haujlwm txuas ntxiv. Ib txoj hauv kev uas lawv siv yog cov txheej txheem ntawm hypertrophy.
Hypertrophied cells
Raws li cell loj hlob, qee qhovme me intracellular organelles, xws li mitochondria, yuav nce nyob rau hauv tus naj npawb kom txhua chav loj.
Zoo los phem?
nce qhov loj tuaj yeem yog ob qho tib si thiab kab mob. Zoo hypertrophy (tseem hu ua physiological) tuaj yeem tshwm sim rau ntau hom hlwb thoob plaws hauv lub cev. Qee qhov xwm txheej tuaj yeem ua rau cov khoom me tshaj plaws, thiab yog li cov kabmob thiab cov ntaub so ntswg uas ua rau lawv, kom loj tuaj. Yuav ua li cas txiav txim siab yog tias hypertrophy yog physiological lossis pathological? Qhov no tuaj yeem pom zoo nrog cov piv txwv.
Physiological hypertrophy
Cia hais tias koj xav tsim biceps hauv koj txhais caj npab thiab ua kom cov leeg muaj zog. Txhawm rau ua tiav qhov no, koj pib koom nrog qhov kev pabcuam tshwj xeeb uas suav nrog kev nqa qhov hnyav. Tom qab ob peb lub lis piam, koj biceps loj dua thiab koj muaj zog ntau dua li ua ntej. Dab tsi tshwm sim? Kev nqa hnyav ua rau muaj kev nce ntxiv ntawm cov leeg nqaij, uas txhawb kev pib ntawm cov txheej txheem ntawm cellular adaptation. Hom hypertrophy no yog qhov qub thiab xav tau, nrog rau kev hloov pauv ntawm cov leeg nqaij thiab nce lawv lub zog thiab kev ua haujlwm.
Lub cev muaj zog tuaj yeem tshwm sim hauv lub siab nrog kev ua haujlwm ntau ntxiv. Qhov no tuaj yeem pom hauv cov neeg ncaws pob uas niaj hnub koom nrog kev mob siabkev tawm dag zog. Nyob rau hauv cov ntaub ntawv no, hypertrophy ntawm ib tug neeg lub hlwb ua rau ib tug nce nyob rau hauv cov nqaij ntshiv, raws li zoo raws li nce lub plawv muaj nuj nqi thiab muaj zog endurance. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias physiological hypertrophy yog thim rov qab, yog li thaum kev tawm dag zog qis dua lossis nres, qhov hypertrophied (hauv peb qhov xwm txheej, qhov loj dua) lub cev rov qab los rau nws qhov qub (thawj) loj.
YPathological hypertrophy
Lub cev twg yog qhov hnyav? Qhov no yog ib feem ntawm lub cev uas tau raug rau cov txheej txheem hypertrophy. Nws hom txawv txav kuj hu ua pathological. Nws tuaj yeem tshwm sim rau ntau qhov laj thawj. Ib qho piv txwv yog pathological hypertrophy, uas tshwm sim thaum tus neeg mob ntshav siab (hypertension). Kev nce hauv qhov loj ntawm ib qho ntawm lub ventricles ntawm lub plawv, qhov no, yog qhov tsim nyog txhawm rau txhawm rau tiv thaiv cov ntshav kom zoo dua.
Qhov tseeb thiab tsis tseeb hypertrophy
Hypertrophic - txhais los ntawm Greek (hyper - "ntau dhau, dhau los" thiab trophy - "kev noj haus, zaub mov, khoom noj") txhais tau tias nce ntim. Cov no tuaj yeem yog cov hlwb, cov ntaub so ntswg, cov kabmob uas pib loj hlob los ntawm ntau yam.
Dab tsi ntawm qhov tseeb thiab tsis tseeb hypertrophy. Qhov thib ib yog tus cwj pwm los ntawm kev loj hlob ntawm cov ntaub so ntswg adipose, qhov thib ob yog raws li kev nce hauv cov leeg ua haujlwm hauv cov neeg koom nrog kev ua kis las lossis lwm yam kev ua haujlwm lub cev.
Lub ntsiab lus ntawm lo lus: hypertrophied
Qhov no, ntawm qhov tseeb ntawm lo lus,nce nyob rau hauv ntim (vim mob, lub cev exertion). Hauv kev txiav txim siab, lo lus no txhais tau tias ntau dhau ntawm ib yam dab tsi. Yog li, qhov kev xav ntawm hypertrophied yog qhov exaggerated (embellished) kev xav. Tib yam tuaj yeem hais txog qhov zoo, cov khoom thiab lwm yam. Piv txwv li, ib tug hypertrophied self-preservation instinct yog txuam nrog nce, unjustified ntshai rau ib tug lub neej, thiab lwm yam.
