Qhov sib txawv tseem ceeb ntawm collagen elastin thiab reticular fibers yog collagen fibers yog hom fiber ntau tshaj plaws nyob rau hauv extracellular matrix ntawm connective cov ntaub so ntswg thaum elastin fibers yog me me fibers uas yuav stretch thiab recoil thiab lawv muaj nyob rau hauv cov ntaub so ntswg elastic.. Lub caij no, cov fibers reticular yog cov ceg tawv heev uas tsim kom muaj kev sib txuas hauv lub cev uas muaj ntau lub mesh zoo li sab hauv.
Cov ntaub so ntswg sib txuas yog cov ntaub so ntswg ntau tshaj plaws thiab nthuav dav pom hauv peb lub cev. Cov ntaub so ntswg tuav peb cov ntaub so ntswg thiab lub cev ua ke. Yog li ntawd, nws txuas, sib cais thiab txhawb nqa tag nrho cov ntaub so ntswg hauv peb lub cev. Cov ntaub so ntswg sib txuas kuj tiv thaiv peb cov ntaub so ntswg los ntawm kev raug mob. Cells, fibers thiab hauv av khoom yog peb lub ntsiab tseem ceeb ntawm cov ntaub so ntswg. Fibers pom nyob rau hauv cov ntaub so ntswg sib txuas tuaj yeem muab faib ua peb hom xws li collagen, elastin thiab reticular protein fibers. Collagen fibers yog cov muaj zog tshaj thiab tuab fibers. Elastin fibers yog thinner fibers uas yuav stretch thiab recoil. Reticular fibers, ntawm qhov tod tes, yog cov ceg me me uas muaj fiber ntau pom hauv cov kabmob uas muaj ntau cov qauv mesh zoo li.
YCollagen Fibers yog dab tsi?
Collagen fibers yog cov protein ntau tshaj plaws uas pom muaj nyob rau hauv extracellular matrix ntawm cov ntaub so ntswg sib txuas. Lawv yog xim dawb fibers. Ntawm peb hom fibers pom nyob rau hauv cov ntaub so ntswg sib txuas, collagen fibers yog cov thickest thiab muaj zog tshaj. Lawv yog cov me me tab sis muaj zog fibers. Collagen fibers yog tsim los ntawm collagen fibrils uas yog xov zoo li cov sub-units. Lawv yog ua los ntawm cov pab pawg ntawm triplets ntawm ib tug neeg collagen molecules uas yog teem ib sab. Collagen fibrils muaj tus yam ntxwv 64 nm banded tsos.
Daim duab 01: Collagen Fibers
Collagen yog cov protein uas muaj txog 30 subtypes. Ntawm lawv, 4 hom feem ntau sawv cev. Lawv yog collagen hom I, hom II, hom III thiab hom VI. Collagen type I yog hom collagen ntau tshaj plaws thiab suav txog 90% ntawm lub cev collagen. Hom I muaj nyob rau hauv daim tawv nqaij ntawm daim tawv nqaij, pob txha, leeg, fasciae, organ capsules thiab ntau qhov chaw. Collagen fibers ua rau lub moj khaum extracellular ntawm tag nrho cov ntaub so ntswg. Lawv tseem ceeb heev rau lub zog tensile.
YElastin Fibers yog dab tsi?
Elastin fibers yog ib hom protein fibers pom nyob rau hauv cov ntaub so ntswg sib txuas. Lawv kuj hu ua daj fibers. Elastin fibers tuaj yeem ncab thiab rov qab. Nws tuaj yeem rov qab mus rau nws qhov qub qub thaum nws ncab lossis compressed. Lawv yog tsim los ntawm cov roj hmab zoo li cov protein hu ua elastin.
Daim duab 02: Elastin Fibers
Ntxiv mus, lawv muaj tsawg dua ntawm lwm cov proteins (elaunin thiab oxytalan) thiab glycoproteins. Elastin fibers muaj ntau nyob rau hauv cov ntaub so ntswg elastic pom nyob rau hauv daim tawv nqaij thiab elastic ligaments ntawm vertebral kem.
Reticular Fibers yog dab tsi?
Reticular fibers yog ib hom protein fibers pom nyob rau hauv cov ntaub so ntswg reticular. Reticular fibers yog tsim los ntawm zoo heev collagen fibrils uas tshwm li 64 nm bandings.
Daim duab 03: Reticular Fibers
Reticular fibers yog cov ceg tawv heev thiab tsim ib lub network muag heev. Yog li ntawd, lawv feem ntau pom nyob rau hauv lub cev uas muaj ntau mesh zoo li cov qauv sab hauv. Spleen thiab lymphoid organ yog ob lub cev. Spleen yog tag nrho ntawm reticular fibers vim nws ua raws li lub lim. Ntxiv mus, reticular fibers yog argyrophilic fibers uas stain nrog ammoniacal silver solutions.
Dab tsi zoo sib xws ntawm Collagen Elastin thiab Reticular Fibers?
- Collagen, elastin thiab reticular yog peb hom protein fibers pom nyob rau hauv cov ntaub so ntswg.
- Extracellular matrix ntawm cov ntaub so ntswg sib txuas yog tsim los ntawm peb hom fibers.
- Txhua peb fibers yog embedded rau hauv av.
- Cov ntaub so ntswg xoob muaj tag nrho peb hom fibers.
- Cov fibers no muab kev txhawb nqa rau cov ntaub so ntswg thiab lub cev.
Qhov txawv ntawm Collagen Elastin thiab Reticular Fibers yog dab tsi?
Collagen fibers yog qhov muaj zog tshaj plaws thiab tuab tshaj plaws protein fibers pom muaj nyob hauv cov ntaub so ntswg sib txuas. Elastin fibers yog thinner fibers uas yuav ncab thiab recoil thaum reticular fibers yog heev branched ilv fibers pom nyob rau hauv lub cev uas muaj ntau ntau mesh zoo li cov qauv. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm collagen elastin thiab reticular fibers.
Ntxiv mus, nyob rau hauv cov ntaub so ntswg sib txuas, collagen fibers yog ntau tshaj plaws nyob rau hauv ntau hom kev sib txuas cov ntaub so ntswg, thaum elastin fibers tseem ceeb nyob rau hauv cov ntaub so ntswg elastic thiab reticular fibers tseem ceeb nyob rau hauv lub poov xab thiab lymphoid organ. Collagen fibers thiab reticular fibers yog tsim los ntawm collagen fibrils thaum elastin fibers yog tsim los ntawm elastin fibers.
Hauv qab infographic tabulates qhov sib txawv ntawm collagen elastin thiab reticular fibers rau kev sib piv ntawm ib sab.
Summary – Collagen Elastin vs Reticular Fibers
Collagen, elastin thiab reticular fibers yog peb hom protein fibers pom nyob rau hauv cov ntaub so ntswg sib txuas. Collagen fibers yog ntau hom fibers nyob rau hauv ib qho extracellular matrix ntawm connective cov ntaub so ntswg. Lawv yog tsim los ntawm collagen fibers thiab lawv yog cov muaj zog thiab thickest fibers. Elastin fibers yog cov tseem ceeb fibers nyob rau hauv cov ntaub so ntswg elastic pom nyob rau hauv daim tawv nqaij thiab elastic ligaments ntawm vertebral kem. Lawv feem ntau yog tsim los ntawm pob khoom ntawm elastin proteins. Reticular proteins yog feem ntau branched luv fibers feem ntau pom nyob rau hauv lub nruab nrog cev uas muaj ntau mesh zoo li cov qauv sab hauv. Yog li ntawd, cov fibers reticular muaj ntau nyob rau hauv spleen thiab lymphoid lub cev. Yog li, qhov no qhia txog qhov sib txawv ntawm collagen elastin thiab reticular fibers.
