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 ntawm cov theem twg yog granulation cov ntaub so ntswg tsim?
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.
hom cell pib cov ntaub so ntswg granulation?
Fibroblasts, cov hlwb tseem ceeb uas tso cov ntaub so ntswg granulation, nyob ntawm cov pa kom proliferate thiab nteg cov tshiab extracellular matrix. Hauv vascularisation, tseem hu ua angiogenesis, cov hlwb endothelial sai sai loj hlob mus rau hauv cov ntaub so ntswg los ntawm cov hlab ntsha laus.
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.
Yuav tsum tshem cov ntaub so ntswg granulation?
Nws tau lees paub los ntawm cov xim liab liab mus rau tsaus liab, feem ntau ci ntsa iab thiab muag muag, uas tau nce mus rau qib ntawm cov tawv nqaij ib puag ncig lossis siab dua. Daim ntaub no mustraug tshem tawm kom thiaj li rov ua epithelialization tshwm sim.

Lub sijhawm embryonic txoj kev loj hlob cov ntaub so ntswg twg yog tsim ua ntej?
thaum lub sij hawm txheej txheem ntawm embryonic txoj kev loj hlob, endoderm yog thawj txheej kab mob yuav tsum tau tsim thaum lub sij hawm gastrula theem. Epithelial cov ntaub so ntswg yog muab los ntawm tag nrho peb txheej kab mob, ectoderm, mesoderm thiab endoderm.
Nyob rau hauv cov kev tsim tawm no suav nrog kev tsim cov gemmule?
C) Asexual reproduction tshwm sim nyob rau hauv spongilla los ntawm kev loj hlob ntawm gemmules. Spongilla belongs rau Porifera Porifera Ib daim txhuam cev yog ib qho cuab yeej lossis kev pab tu ua los ntawm soft, porous khoom. Feem ntau siv los ntxuav qhov chaw impervious, sponges yog tshwj xeeb tshaj yog zoo ntawm absorbing dej thiab dej raws li kev daws teeb meem.
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.
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.
