Primary cartilaginous pob qij txha yog hu ua "synchondrosis". Cov pob txha no txuas nrog hyaline pob txha mos thiab qee zaum tshwm sim ntawm cov chaw ossification. Qhov no pob txha mos tuaj yeem ua rau muaj hnub nyoog. Qee qhov piv txwv ntawm thawj pob txha pob txha mos nyob rau hauv tib neeg yog cov "plaws loj hlob" ntawm ossification chaw nyob rau hauv cov pob txha ntev.
Ib yam li ntawd, tib neeg nug, ob hom pob txha mos yog dab tsi?
Muaj ob hom kab mob cartilaginous: synchondroses thiab symphyses. Hauv synchondrosis, tus pob txha koom nrog hyaline pob txha mos . Synchondroses muaj nyob hauv daim phiaj epiphyseal ntawm kev loj hlob pob txha hauv cov menyuam yaus.
Ib yam li ntawd, kev ua haujlwm ntawm cartilaginous leeg yog dab tsi? Cartilaginous pob qij txha txuas tag nrho los ntawm pob txha mos (fibrocartilage lossis hyaline). Cartilaginous pob qij txha tso cai ntxiv zog nruab nrab ntawm cov pob txha tshaj ib tug fibrous sib koom tab sis tsawg tshaj li mobile synovial sib koom. Kev sib koom ua ke ntawm manubrium thiab sternum yog ib qho piv txwv ntawm ib qho cartilaginous leeg.
Dhau li ntawm saum toj no, dab tsi yog cov pob qij txha pob txha pob txha pob txha thiab theem nrab?
Thawj pob txha pob txha mos kuj tseem hu ua synchondroses. Cov pob txha mos, hyaline lossis fibrocartilage, feem ntau hloov mus rau pob txha nrog hnub nyoog, tshwj tsis yog qhov no yog qhov pob qij txha tuav thawj tav rau lub manubrium ntawm lub sternum, thiab sternal synchondroses. Secondary cartilaginous pob qij txha kuj tseem hu ua symphyses.
Lub duav puas yog cartilaginous sib koom?
Ib tug synchondrosis yog ib tug cartilaginous sib koom tes qhov twg cov pob txha tau koom nrog hyaline pob txha mos . (b) Cov pubic feem ntawm sab xis thiab sab laug nqaj Cov pob txha ntawm pelvis tau koom ua ke los ntawm fibrocartilage, tsim cov pubic symphysis.

Yam kev sib koom tes yog Midcarpal sib koom tes yog dab tsi?
Qhov nruab nrab nruab nrab ntawm pob qij txha yog ua ke ntawm synovial gliding pob qij txha ntawm cov kab sib thooj thiab nyob deb ntawm cov pob txha carpal. Zoo li lwm yam kev sib koom ua ke, cov pob txha carpal uas nyob ib sab hauv nruab nrab lub cev sib koom ua ke nrog cov pob txha hyaline thiab cov kab noj hniav sib koom ua ke nyob rau hauv cov tshuaj ua kua fibrous kab nrog synovial membrane
Cov kab mob sib koom ua ke twg yog tus cwj pwm los ntawm kev sib koom ua ke ntawm kev txav mus los thiab kev sib koom ua ke ntawm qhov hnyav ntawm cov pob qij txha uas feem ntau yog relieved los ntawm so?
Osteoarthritis feem ntau cuam tshuam rau txhais tes, qis nraub qaum, caj dab, thiab hnyav sib koom tes xws li hauv caug, lub duav, thiab ko taw
Hom kev sib koom ua ke yog qhov sib koom ua ke ntawm atlantoaxial?
pivot sib Tom qab ntawd, ib tug kuj yuav nug, hom kev sib koom ua ke yog atlanto occipital joint? condyloid Ib yam li ntawd, cov lus tsa suab twg yog qhov sib koom ua ke ntawm atlantoaxial tso cai? Lub atlas thiab axis tshwj xeeb ua haujlwm nrog ligaments txav caj dab.
Qhov sib txawv ntawm kev noj qab haus huv tsis sib xws thiab kev noj qab haus huv tsis sib xws yog dab tsi?
