Granulation ntaub so ntswg yog tsim thaum lub sijhawm kho. Qhov no yog ib tug complex ntawm fibroblasts, vascular endothelial hlwb, thiab macrophages nyob rau hauv ib tug matrix ntawm collagen thiab fibrin. Fibroblasts thiab capillaries tshwm nyob rau hauv lub qhov txhab los ntawm hnub 3. Fibroblasts siv cov fibrin clot ua ib tug matrix thiab hloov nws nrog tshiab matrix.
Lub sijhawm twg yog cov ntaub so ntswg granulation?
theem proliferative yog yam ntxwv los ntawm kev tsim cov ntaub so ntswg granulation, reepithelialization, thiab neovascularization. Cov theem no tuaj yeem kav ntev li ob peb lub lis piam.
Lub luag haujlwm dab tsi rau kev tsim cov ntaub so ntswg granulation?
Granulation cov ntaub so ntswg pib tshwm thiab yog tsim los ntawm cov ntaub so ntswg tshiab thiab cov hlab ntsha me me thiab yog vim cov kev ua haujlwm fibroblast thiab macrophage, uas muab lub hauv paus ntawm kev loj hlob yam tseem ceeb uas tswj. angiogenesis thiab fibroplasia [43, 44].
Granulation theem yog dab tsi?
Theem granulation. Lub sijhawm thib peb ntawm kev kho qhov txhab, suav nrog kev hloov pauv ntawm cov fibrin matrix ib ntus nrog cov ntaub so ntswg granulation thaum lub qhov txhab tau raug tshem tawm, suav nrog ob peb theem: rov ua epithelialization. fibroplasia, collagen deposition.
Cov ntaub so ntswg puas yuav tsum tau muab tshem tawm?
Yog nws tsis tawm los yooj yim, cia nws tawm. Hauv qab cov exudates, koj tuaj yeem pom kev noj qab haus huv, cov ntaub so ntswg liab loj hlob ntawm qhov txhab. Qhov no yog granulation ntaub so ntswgthiab yog qhov tsim nyog rau kev kho mob. Cov tawv liab liab tshiab yuav loj hlob ntawm ntug mus rau qhov chaw ntawm qhov txhab, hla cov ntaub so ntswg granulation.
Pom zoo:
Lub sijhawm ua cov ntaub so ntswg yog dab tsi yog qhov tseeb ntawm cov kauj ruam?
Nws muaj peb kauj ruam tseem ceeb hauv kev ua cov ntaub so ntswg, uas yog: 'dehydration', 'clearing', thiab 'infiltration'. Txhua kauj ruam ntawm kev ua txheej txheem suav nrog kev sib kis ntawm cov tshuaj rau hauv cov ntaub so ntswg thiab dispersion ntawm cov tshuaj yav dhau los hauv koob.
Dab tsi yog peb cov ntaub qhwv cov ntaub so ntswg hauv cov leeg?
Cov ntaub so ntswg interstitial ntawm cov leeg yog subdivided rau hauv epimysium epimysium Lub epimysium yog cov ntaub so ntswg ntom ntom uas nyob ib puag ncig tag nrho cov leeg nqaij. Lub epimysium feem ntau muaj ntau pob (fascicles) ntawm cov leeg nqaij.
Cov ntaub so ntswg mesodermal yog tsim los ntawm cov txheej txheem qub?
Cov hlwb ntawm lub hauv paus ntawm lub xub ntiag zais ntau lub xov tooj ntawm tes uas tseem ceeb rau kev sib txawv ntawm neural. Tom qab gastrulation lub embryo tsim tau muab faib ua ectoderm, mesoderm, thiab endoderm. Lub ectoderm ua rau cov ntaub so ntswg epithelial thiab neural, nrog rau cov ntaub so ntswg neural yog lub neej ua haujlwm ntawm tes.
Dab tsi yog cov kab mob photosynthetic pom nyob rau hauv cov ntaub so ntswg ntawm coral?
Feem ntau cov pob zeb tsim cov pob zeb muaj cov photosynthetic algae, hu ua zooxanthellae, uas nyob hauv lawv cov ntaub so ntswg. Corals thiab algae muaj kev sib raug zoo. Lub coral muab cov algae nrog kev tiv thaiv ib puag ncig thiab cov tebchaw uas lawv xav tau rau photosynthesis.
Puas cov ntaub so ntswg epithelial puas muaj cov ntaub so ntswg hauv qab daus?
Ntseeg ntawm Epithelia Epithelial hlwb txuas rau ib hom tshwj xeeb ntawm extracellular matrix hu ua basal lamina basal lamina Lub basal lamina yog txheej ntawm extracellular matrix secreted los ntawm cov epithelial hlwb, ntawm uas lub epithelium zaum.
