Cov ntsiab lus sib txawv ntawm cov ntaub so ntswg sib txuas yog cov khoom siv sib txuas tau xoob tau xoob cov ntaub so ntswg tau siv ntau dua cov ntaub qhwv tau ua tiav cov kab ke.

Muaj plaub hom ntaub so ntswg hauv tib neeg lub cev: cov ntaub so ntswg epithelial, cov ntaub so ntswg sib txuas, cov leeg nqaij, thiab cov ntaub so ntswg. Xav txog nws cov qauv thiab ntau yam kev ua haujlwm, cov ntaub so ntswg sib txuas yog cov ntaub so ntswg paub ntau tshaj plaws ntawm txhua cov ntaub so ntswg. Cov qauv ntawm cov ntaub so ntswg sib txawv los ntawm cov mos gel zoo li xoob (areolar) cov ntaub so ntswg mus rau cov pob txha tawv. Kev pom ntawm extracellular matrix nrog cov khoom hauv av thiab fibers yog cov yam ntxwv tshwj xeeb ntawm cov ntaub so ntswg tshwj xeeb. Raws li hom thiab cov txheeb ze ntau ntawm cov hlwb nrog rau lub koom haum ntawm fibers thiab hauv av, cov ntaub so ntswg tuaj yeem muab faib ua ntau pawg. Cov ntaub so ntswg xoob thiab ntom ntom yog ob pawg tseem ceeb ntawm lawv.

Cov ntaub so ntswg Loose Connective yog dab tsi?

Cov ntaub so ntswg xoob yog lub npe xws li vim qhov xoob ntawm fibers thiab hlwb hauv matrix. Nws cov viscous gel zoo li xwm yog qhov tseem ceeb rau cov pa oxygen thiab cov khoom noj muaj txiaj ntsig los ntawm cov hlab ntsha me thiab nthuav cov metabolites rov qab mus rau cov hlab ntsha. Ntxiv mus, cov ntaub so ntswg xoob tuaj yeem pom hauv qab cov ntaub so ntswg epithelial uas kab ntawm lub cev sab hauv, qog, thiab ib ncig ntawm cov hlab ntsha me.

Daim duab 01: Loose Connective Tissue

Cov xovtooj tseem ceeb hauv cov ntaub so ntswg xoob yog fibroblasts, uas tsim thiab tswj cov fibers thiab hauv av ntawm matrix. Lawv yog cov hlwb zoo li spindle thiab feem ntau tawg mus thoob plaws hauv matrix. Txawm hais tias fibers tsis muaj ntau hauv cov ntaub so ntswg xoob, collagen fibers yog hom fiber ntau tam sim no hauv cov ntaub so ntswg xoob. Cov ntaub so ntswg Areolar, cov ntaub so ntswg reticular, thiab cov ntaub so ntswg adipose yog qee yam ntawm cov ntaub so ntswg xoob.

Dense Connective Tissue yog dab tsi?

fibers muaj ntau thiab densely tau teem rau hauv cov ntaub so ntswg sib txuas, txawm tias nws muaj tib lub hlwb, cov yeeb yaj kiab av, thiab cov fibers raws li xoob cov ntaub so ntswg sib txuas. Cov ntaub so ntswg ntom ntom muaj nyob hauv thaj chaw uas xav tau lub zog. Raws li kev npaj ntawm cov fibers, cov ntaub so ntswg ntom ntom muaj nyob rau hauv ob hom sib txawv: cov ntaub so ntswg tsis sib xws thiab cov ntaub so ntswg ntom ntom.

Daim duab 02: Nthuav Connective Tissue

Nyob rau hauv cov ntaub so ntswg tsis sib xws, cov fibers tsis muaj kev taw qhia tshwj xeeb ntawm kev teeb tsa. Yog li ntawd, lawv muaj nyob rau hauv qhov chaw uas muaj kev ntxhov siab tshwm sim nyob rau hauv ntau cov lus qhia. Hauv cov ntaub so ntswg tsis tu ncua, cov txheej txheem fiber ntau yog sib npaug rau ib leeg hauv ib qho kev coj. Yog li ntawd, lawv muaj nyob rau hauv qhov chaw uas muaj zog siv nyob rau hauv ib qho kev taw qhia. Tsis tas li ntawd, cov ntaub so ntswg tsis tu ncua muaj ob hom ntxiv xws li cov ntaub so ntswg collagenous thiab ntom elastic connective cov ntaub so ntswg. Dense collagenous connective cov ntaub so ntswg muaj lub tensile lub zog ntawm collagen thaum ntom elastic connective ntaub so ntswg muaj lub elasticity ntawm elastin.

Dab tsi yog qhov zoo sib xws ntawm Loose and Dense Connective Tissue?

  • Cov ntaub so ntswg xoob thiab ntom ntom yog ob hom kab sib txuas hauv peb lub cev.
  • Ob cov ntaub so ntswg muaj collagen fibers.
  • Ntxiv mus, lawv muaj fibroblasts.
  • Ntxiv rau, lawv muab kev txhawb nqa thiab txuas ntau cov ntaub so ntswg thiab cov kabmob hauv peb lub cev.

Qhov txawv ntawm Loose thiab Dense Connective Tissue yog dab tsi?

Cov ntaub so ntswg xoob yog ib pawg ntawm cov ntaub so ntswg uas muaj ntau hauv peb lub cev thiab muaj ob peb fibers hauv matrix thaum cov ntaub so ntswg ntom ntom yog ib hom kab mob sib txuas uas muaj fiber ntau hauv matrix. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cov ntaub so ntswg xoob thiab ntom ntom. Tsis tas li ntawd, feem ntau ntawm cov khoom hauv av thiab cov hlwb muaj nyob rau hauv cov ntaub so ntswg xoob, thaum cov tshuaj no muaj nyob rau hauv me me hauv cov ntaub so ntswg ntom. Tsis tas li ntawd, ob peb cov txheej txheem xoob xoob tuaj yeem pom hauv cov ntaub so ntswg xoob, whereas nyob rau hauv cov ntaub so ntswg ntom ntom, fibers muaj ntau thiab ntom ntom.

Muaj lwm qhov sib txawv ntawm cov ntaub so ntswg sib npaug yog cov ntaub so ntswg sib txuas muaj ntau cov nkoj ntau dua li cov ntaub so ntswg sib txuas. Tsis tas li ntawd, lawv qhov chaw kuj yog qhov sib txawv ntawm qhov sib txawv ntawm cov ntaub so ntswg xoob thiab ntom ntom. Cov ntaub so ntswg xoob yog tam sim no nyob rau hauv cov ntaub so ntswg epithelial uas kab ntawm lub cev sab hauv, qog, thiab ib ncig ntawm cov hlab ntsha me. Whereas, lub qhov tob sib txuas yog nyob rau sab nraud ntawm cov tawv nqaij sib txuas, thiab cov kab mob sab nrauv, thiab aponuroses zoo li cov ntaub so ntswg sib txuas.

Summary – Loose vs Dense Connective Tissue

Cov ntaub so ntswg xoob thiab ntom ntom yog ob pawg ntawm cov ntaub so ntswg sib txuas. Cov ntaub so ntswg xoob yog hom ntau tshaj plaws. Nws muaj cov txheej txheem xoob xoob thiab cov hlwb. Txawm li cas los xij, cov ntaub so ntswg ntom ntom yog tsawg dua, thiab nws muaj ntau cov fibers hauv matrix. Muaj ob hom kev sib txuas cov ntaub so ntswg sib txuas zoo li cov ntaub so ntswg sib txuas thiab cov ntaub so ntswg sib txuas. Ib yam li ntawd, cov ntaub so ntswg isolar, cov ntaub so ntswg reticular, thiab cov ntaub so ntswg adipose yog qee yam ntawm cov ntaub so ntswg xoob. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm cov ntaub so ntswg xoob thiab ntom ntom.
