Cov pob txha mos thiab meniscus yog ob hom pob txha mos hauv pob qij txha. Lawv lub luag haujlwm tseem ceeb yog muab qhov chaw du thiab ruaj khov rau kev sib koom ua ke (sib koom), uas cuam tshuam rau kev txav mus los hauv tib neeg lub cev. Ob leeg pob txha mos raug raug mob, uas yuav cuam tshuam rau kev ua haujlwm hauv lub cev.
Cov pob txha mos Articular yog dab tsi?
Articular pob txha mos yog ib hom pob txha mos uas pom hauv lub hauv caug, pob taws, lub duav, lub xub pwg nyom, lub luj tshib, dab teg, thiab ntiv tes pob qij txha, uas tso cai rau lawv swb dawb. Nws yog cov pob txha mos hyaline uas yog 2 mus rau 4 hli hauv tuab. Articular pob txha mos tsis muaj cov hlab ntsha, paj hlwb, lossis cov ntaub so ntswg lymphatic. Nws yog tsim los ntawm cov extracellular matrix (ECM) nrog cov faib sib luag ntawm cov hlwb tshwj xeeb hu ua chaondrocytes. ECM muaj dej, collagen, proteoglycans thiab lwm yam noncollagenous proteins, thiab glycoproteins tsawg dua. Cov khoom siv no pab khaws cov dej hauv ECM, uas yog qhov tseem ceeb rau kev tswj hwm nws cov khoom siv tshuab tshwj xeeb. Lub ultrastructure ntawm collagen fiber, ECM, thiab chondrocytes pab txhawb rau ntau thaj chaw ntawm pob txha pob txha: nruab nrab, cheeb tsam sib sib zog nqus, thiab calcified zone. Tsis tas li ntawd, nyob rau hauv txhua cheeb tsam, peb cheeb tsam tshwj xeeb tuaj yeem txheeb xyuas tau: cheeb tsam pericellular, thaj chaw thaj chaw, thiab thaj chaw interterritorial.
Daim duab 01: Pob txha mos pob txha
Qhov kev ua haujlwm ntawm pob txha pob txha pob txha yog los muab ib qho smooth, lubricated nto rau articulation. Nws kuj tseem pab txhawb kev sib kis ntawm cov khoom thauj nrog kev sib txhuam coefficient tsawg. Articular pob txha mos tuaj yeem tshwm sim los ntawm ntau yam xws li kev raug mob, osteoarthritis, siv ntau dhau, cov leeg tsis muaj zog, pob txha misalignment, rog rog, thiab mob caj dab. Tsis tas li ntawd, kev raug mob rau pob txha pob txha pob txha raug lees paub tias yog ib qho ua rau mob musculoskeletal morbidity.
Meniscus yog dab tsi?
Meniscus yog ib hom pob txha mos pom nyob rau hauv lub hauv caug, dab teg, acromioclavicular, sternoclavicular, thiab temporomandibular pob qij txha thiab feem ntau ua raws li kev poob siab absorber. Nws yog ib tug crescent-shaped fibrocartilaginous anatomical qauv uas tsuas yog ib feem faib cov kab noj hniav. Menisci ntawm lub hauv caug yog ob lub ncoo ntawm cov ntaub so ntswg fibrocartilaginous. Lawv ua hauj lwm rau disperse kev sib txhuam nyob rau hauv lub hauv caug pob qij txha ntawm sab ceg thiab ncej puab. Lawv yog concave rau saum thiab tiaj tus nyob rau hauv qab, articulating nrog tibia. Ntxiv mus, lawv txuas nrog kev nyuaj siab me me ntawm cov condyles ntawm tibia. Mus rau qhov chaw, lawv tsis sib txuas, thiab lawv cov duab nqaim mus rau lub txee nyias.
Daim duab 02: Meniscus
Cov ntshav ntws ntawm meniscus yog los ntawm qhov chaw mus rau hauv nruab nrab meniscus. Ntawm MRI cov duab, menisci qhia kev siv qis. Tsis tas li ntawd, lub luag haujlwm tseem ceeb ntawm menisci yog dispersing qhov hnyav ntawm lub cev thiab txo kev sib txhuam thaum txav mus.
Dab tsi yog qhov zoo sib xws ntawm Articular pob txha mos thiab Meniscus?
- pob txha mos thiab meniscus yog ob hom pob txha mos hauv pob qij txha.
- Ob pob txha mos tuaj yeem pom hauv qhov chaw xws li hauv caug.
- Cov pob txha mos no pab hloov pauv ntawm tib neeg lub cev.
- Ob leeg pob txha mos raug raug mob, uas yuav cuam tshuam rau kev ua haujlwm hauv lub cev hauv lub cev.
Qhov txawv ntawm Articular pob txha mos thiab Meniscus yog dab tsi?
Articular pob txha mos yog ib hom pob txha mos pom nyob rau hauv lub hauv caug, pob taws, lub duav, lub xub pwg, lub luj tshib, dab teg, thiab ntiv tes pob qij txha, uas tso cai rau lawv swb dawb thaum meniscus yog ib hom pob txha mos pom hauv lub hauv caug, dab teg., acromioclavicular, sternoclavicular thiab temporomandibular pob qij txha, thiab feem ntau ua raws li kev poob siab absorber. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cov pob txha mos thiab meniscus. Tsis tas li ntawd, cov pob txha mos tsis muaj cov hlab ntsha, paj hlwb, lossis cov ntaub so ntswg lymphatic, thaum meniscus muaj lawv.
Cov hauv qab no qhia txog qhov sib txawv ntawm pob txha mos thiab meniscus hauv daim ntawv qhia rau kev sib piv ntawm ib sab.
Summary – Articular pob txha mos vs Meniscus
