Qhov sib txawv tseem ceeb ntawm bursa thiab cov kua dej synovial yog tias bursa yog ib lub hnab ntim me me uas muaj nyob ib ncig ntawm kev sib koom ua ke thaum cov kua dej synovial yog cov kua nplaum, cov kua nplaum uas ua rau cov kab noj hniav ntawm cov pob qij txha.
Synovial pob qij txha pab txhawb kev txav ntawm cov pob txha. Synovial kab noj hniav yog tam sim no nyob rau hauv ib tug synovial sib koom, thiab nws yog sau nrog synovial kua. Cov kua dej synovial pab txhawb lub lubrication, kev faib khoom noj thiab kev poob siab. Bursa yog ib qho qauv ntxiv nyob ze ntawm qhov sib koom ua ke synovial. Nws yog ib lub hnab ntim me me uas muaj cov kua dej uas muaj feem cuam tshuam rau kev txo qis kev sib txhuam ntawm cov pob txha ntawm kev sib koom tes. Yog li ntawd, ob leeg synovial kua thiab bursa ua raws li kev poob siab absorbers hauv cov pob qij txha.
Bursa yog dab tsi?
Bursae yog cov kua dej me me uas muaj cov kua nplaum uas nyob ib puag ncig ib puag ncig. Lawv nyob ib puag ncig los ntawm cov kab mob synovial thiab muaj cov kua dej synovial. Thaum cov leeg, leeg, daim tawv nqaij thiab ligament glides hla cov pob txha thaum lub sij hawm sib koom tes, bursa muab lub ncoo nyias thiab txo qhov kev sib txhuam. Yog li ntawd, bursae feem ntau cushion cov pob txha thiaj li yuav txo tau kev sib txhuam. Hauv tib neeg lub cev, muaj txog 150 bursae - txhua tus zoo li lub zais pa dej me me. Lawv feem ntau yog muaj thaum yug los. Txawm li cas los xij, qee qhov yuav tshwm sim tom qab hauv thaj chaw uas nquag muaj kev sib txhuam.

Synovial sib koom ua ke yog hom kev sib koom ua ke tshaj plaws hauv tib neeg. Nws koom nrog cov pob txha nrog cov tshuaj fiber ntau. Nyob rau hauv lub synovial kev sib koom tes muaj ib tug muaj kua-filled kab noj hniav. Qhov no synovial kab noj hniav yog sau nrog synovial kua. Cov kua dej synovial yog cov kua nplaum uas muaj qe dawb zoo li sib xws.
Daim duab 02: Synovial Fluid
Synovial membrane secretes synovial kua, thiab nws yog ib feem ntawm transcellular kua tivthaiv ntawm extracellular kua. Cov kua dej no muaj cov protein tau los ntawm cov ntshav plasma thiab cov proteins uas tsim los ntawm cov hlwb hauv cov ntaub so ntswg. Ntxiv mus, nws muaj hyaluronan, lubricin thiab interstitial kua. Lub luag haujlwm tseem ceeb ntawm cov kua dej synovial yog lubrication, kev faib khoom noj thiab kev poob siab.
Dab tsi zoo sib xws ntawm Bursa thiab Synovial Fluid?
- Ob leeg bursa thiab synovial kua yog shock absorbers.
- Bursae muaj cov kua dej synovial.
- Lawv pab txo kev sib txhuam ntawm cov pob txha hauv kev sib koom ua ke.
Qhov txawv ntawm Bursa thiab Synovial Fluid yog dab tsi?
Bursae yog cov kua dej me me uas ua kom yooj yim txav ntawm cov leeg, ligaments, cov leeg, thiab daim tawv nqaij hla cov pob txha thaum sib koom ua ke thaum cov kua dej synovial yog cov kua dej uas ua rau cov kab noj hniav ntawm qhov sib koom ua ke. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm bursa thiab synovial kua. Tsis tas li ntawd, bursae pom nyob ib ncig ntawm cov leeg, ligaments, cov leeg, thiab daim tawv nqaij txav mus thoob plaws pob txha pob txha thaum cov kua dej synovial nyob rau hauv cov kab noj hniav ntawm lub synovial sib koom ua ke.
Ntxiv mus, cov txheej txheem, bursae yog cov kua dej me me thaum cov kua dej synovial yog cov kua nplaum, nplaum, lubricating kua. Yog li, qhov no yog qhov sib txawv ntawm bursa thiab synovial kua. Tsis tas li, ua haujlwm tau zoo, bursae muab lub ncoo ntawm cov pob txha thiab cov leeg thiab / lossis cov leeg nyob ib puag ncig ntawm kev sib koom ua ke thiab txo cov kev sib txhuam ntawm cov pob txha thaum tsiv thaum cov kua synovial pab hauv lubrication, kev faib khoom noj thiab kev poob siab.
Hauv qab infographic qhia txog qhov sib txawv ntawm bursa thiab synovial kua.
Summary – Bursa vs Synovial Fluid
Bursae yog cov hnab ntim dej me me uas pom nyob ib puag ncig pob qij txha. Cov kua dej synovial yog cov kua nplaum nplaum nplaum nplaum uas ua rau cov kab noj hniav ntawm cov synovial sib koom ua ke. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm bursa thiab synovial kua. Bursa yog lined los ntawm lub synovial membrane, thiab nws yog sau nrog cov kua synovial. Synovial kua muaj proteins, hyaluronan, lubricin thiab interstitial kua. Ob leeg bursa thiab synovial kua txo kev sib txhuam ntawm cov pob txha ntawm cov pob qij txha. Lawv kuj yog shock absorbers.
