Qhov Tseem Ceeb Qhov txawv - Cervical vs Thoracic Vertebrae
Qhia rau peb paub ua ntej qee cov ntaub ntawv hais txog kab vertebral kom nkag siab qhov sib txawv ntawm lub ncauj tsev menyuam thiab thoracic vertebrae. Lub vertebral kem yog cov qauv tseem ceeb ntawm cov pob txha axial hauv tib neeg thiab txhawb nqa lawv txoj hauv kev ntsug. Tsis tas li ntawd, lub vertebral kem tiv thaiv tus txha caj qaum, uas yog ib qho tseem ceeb tshaj plaws ntawm lub paj hlwb. Tib neeg vertebrae yog tsim los ntawm 26 lub pob txha, thiab txhua feem hu ua vertebra. Cov khoom no tau npaj los ua ib qho 'S' zoo li tus, nkhaus ntsug axis. Raws li kev ua haujlwm ntawm vertebra, vertebral kem muaj tsib ntu; cervical, thoracic, lumbar, sacrum, thiab coccyx. Qhov sib txawv tseem ceeb ntawm Cervical thiab Thoracic Vertebrae yog nyob ntawm qhov chaw thiab kev ua haujlwm. Lub ncauj tsev menyuam vertebrae yog thawj xya vertebrae pib ntawm pob txha taub hau thiab thoracic vertebrae nyob nruab nrab ntawm lub ncauj tsev menyuam thiab lub lumbar vertebrae. Hauv tsab xov xwm no, qhov sib txawv ntawm lub ncauj tsev menyuam thiab thoracic vertebrae yuav raug qhia.
Cervical Vertebrae yog dab tsi?
Thawj xya vertebrae pib ntawm pob txha taub hau hu ua cervical vertebrae. Txhua lub ncauj tsev menyuam vertebrae tsuas yog thawj ob muaj cov yam ntxwv dav dav. Thawj cervical vertebra (C1) yog lub npe hu ua atlas vim nws txhawb nqa pob txha taub hau. Nws ua rau cov pob qij txha ntawm atlanto-occipital uas txhawb nqa kev txav ntawm pob txha taub hau. Lub xub ntiag ntawm ib tug foramen hu ua foramen transversarium nyob rau hauv cov txheej txheem transverse yog tshwj xeeb rau lub ncauj tsev menyuam vertebra. Ntxiv mus, cervical vertebra muaj ntev (transversely) thiab nqaim (vertically) laminae. Tsis tas li ntawd, cov txheej txheem spinous ntawm lub ncauj tsev menyuam vertebra yog luv luv thiab bifid.
Dab tsi yog Thoracic Vertebrae?
Muaj 12 thoracic vertebrae nyob nruab nrab ntawm lub ncauj tsev menyuam thiab lub lumbar vertebrae. Cov yam ntxwv tseem ceeb uas yog tshwj xeeb rau thoracic vertebrae yog lub xub ntiag ntawm costal facets rau articulation nrog tav. Cov nqi pheej yig no tuaj yeem pom ntawm ob sab ntawm lub cev vertebral thiab ntawm cov txheej txheem transverse. Lub laminae ntawm thoracic vertebrae yog luv (transversely) thiab dav (vertically) kom cov laminae ntawm cov vertebrae uas nyob ib sab sib tshooj. Cov txheej txheem spinous ntawm thoracic vertebrae yog ntev thiab project downward nyob rau hauv lub thoracic cheeb tsam.
Qhov txawv ntawm Cervical thiab Thoracic Vertebrae yog dab tsi?
Kev txhais ntawm Cervical thiab Thoracic Vertebrae
Cervical vertebrae: Lub ncauj tsev menyuam vertebrae yog lub sab sauv 7 vertebrae nyob rau hauv lub vertebral kem.
Thoracic Vertebrae: Thoracic Vertebrae yog cov vertebrae hauv thaj tsam hauv siab uas cov tav txuas.
Yam ntxwv ntawm Cervical thiab Thoracic Vertebrae
Qhov chaw
Cervical vertebrae: Cervical vertebrae yog nyob nruab nrab ntawm pob txha taub hau thiab thoracic vertebrae.
Thoracic Vertebrae: Thoracic vertebrae nyob nruab nrab ntawm lub ncauj tsev menyuam thiab lumbar vertebrae.
Unique Features
Cervical vertebrae: Cervical vertebra muaj ib tug foramen hu ua foramen transversarium nyob rau hauv cov txheej txheem transverse.
Thoracic vertebrae: Thoracic vertebrae muaj cov nqi qis ntawm ob sab ntawm lub cev vertebral thiab ntawm cov txheej txheem hloov pauv uas pab rau kev sib txuas nrog cov tav.
Cervical vertebrae: Cervical vertebrae have 7 vertebra.
Thoracic Vertebrae: Thoracic vertebrae muaj 12 vertebra.
Laminae ntawm Vertebra
Cervical vertebra: Laminae ntawm Cervical vertebra ntev (transversely) thiab nqaim (vertically).
Thoracic vertebrae: Laminae ntawm Thoracic vertebrae yog luv (transversely) thiab dav (vertically) thiab laminae ntawm cov vertebrae uas nyob ib sab sib tshooj.
Cov txheej txheem spinous ntawm Vertebra
Cervical vertebra: Cov txheej txheem spinous yog luv thiab bifid.
Thoracic vertebra: Cov txheej txheem Spinous yog ntev thiab ua haujlwm qis hauv cheeb tsam thoracic.
Vertebral Body
Cervical vertebra: Nws yog oval zoo li tus thiab me.
Thoracic vertebra: Nws yog lub plawv zoo li tus thiab loj dua.
Vertebral Foramen
Cervical vertebra: Nws loj thiab daim duab peb sab.
Thoracic vertebra: Nws yog me me thiab ncig.
