Cov annulus fibrosus yog ib tug muaj zog radial log-zoo li qauv ua los ntawm lamellae; concentric nplooj ntawv ntawm collagen fibers txuas nrog rau daim phiaj kawg vertebral. Cov ntawv txheeb nyob rau ntau lub kaum sab xis. Cov annulus fibrosus encloses lub nucleus pulposus.
Ib yam li ntawd, tib neeg nug, dab tsi yog lub nucleus pulposus ua los ntawm?
Nucleus Pulposus Txhais. Nucleus pulposus yog lub hauv paus ntawm lub vertebral disc. Lub hauv paus yog muaj los ntawm cov khoom siv zoo li jelly uas suav nrog dej feem ntau, nrog rau kev sib koom ua ke ntawm collagen fibers. Cov txheej txheem sab hauv sab hauv tso cai rau lub vertebral disc kom tiv taus lub zog ntawm kev nrawm thiab torsion.
Tom qab ntawd, lo lus nug yog, annulus fibrosus yog dab tsi? Cov annulus fibrosus yog lub zog wrapping uas ua rau sab nraud ntawm lub intervertebral disc. Nws txoj haujlwm yog kom muaj thiab tiv thaiv cov khoom siv mos uas nyob hauv nruab nrab ntawm lub disc. Qhov chaw mos no hu ua nucleus pulposus.
Qhov thib ob, dab tsi cov ntaub so ntswg tsim lub annulus fibrosus?
Cov intervertebral discs suav nrog lub nplhaib fibrous sab nraud, annulus fibrosus disci intervertebralis, uas nyob ib puag ncig sab hauv zoo li lub hauv paus nruab nrab, cov nucleus pulposus . Lub annulus fibrosus muaj ob peb txheej (laminae) ntawm fibrocartilage ua los ntawm hom I thiab hom II collagen.
Dab tsi yog qhov txawv ntawm nucleus pulposus thiab annulus fibrosus?
Nucleus pulposus : yog mos, ywj, gelatinous core, muaj feem ntau ntawm dej (kwv yees li 75 feem pua) nrog cov pob qij txha tawg thiab cov nqaij ywj. Annulus fibrosus : txheej txheej tawv ntawm fibrous pob txha mos; daim hlau yog tsim ntawm hyaline thiab fibrous pob txha mos.
