Mizu ya mitsempha ya m'mimba ndi mitsempha yambiri yomwe imachokera mu msana. Pa mbali iliyonse ya msana, (yomwe ili m'mbali mwa msana wamtsempha womwe umagwirizana ndi msinkhu wa vertebra umene mitsempha imachokera ku mbali zonse za thupi) pali mizu inayi yoyambira mzere ndi ziwiri kumbuyo.
Kutsogolo, mizu imeneyi-yoyenera ndi yamanzere, mwachitsanzo, imodzi kumbali zonse za msana-ili ndi mitsempha yomwe imayendera kayendetsedwe ka thupi lanu.
Mitsempha ndi mizu ya mitsempha kutsogolo imatchedwa motor neurons.
Kumbuyo, mitsempha (yodzinso kumanja ndi ina kumanzere), imanyamula zidziwitso kuchokera ku thupi kupita mu msana kapena ubongo ndipo zimatchedwa neurons. Ukafika pamtunda wamtsempha kapena ubongo, chidziwitso chodziwika bwino chomwe chimaperekedwa kudzera m'matumbo achizungu amatanthauzidwa ngati kumverera.
Zonsezi, pali mapaundi 31 a mizu ya msana, koma pambuyo pa L-1, yomwe ili mlingo wa loyamba la verbbra yoyamba, khosi la msana limatha. Izi zimatanthawuza kuti mizu ya mitsempha siimatha kuuluka mumtunda wa msana monga momwe amachitira pamwamba pa L-1 M'malo mwa mitsempha ya msana, yomwe imakhala mkati ndi yotetezedwa ndi cerebrospinal fluid, ikugwedeza pansi, ikulowetsa mumtundu wotchedwa cauda equina, kapena conus malingaliro. Cauda equina ndi conus medullaris amatanthawuza "mchira wa kavalo," chomwecho ndi momwe chiwonetserochi chikufanana ndi ena a anatomists.
Kupweteka kwa Mitsempha ya Mitsempha: Ma Radiculopathy
Zina zam'mimba kapena zovulala monga diseni ya herniated , kachilombo koyambitsa matenda ndi / kapena msana wam'mimba amatha kukhumudwitsa mizu ya mitsempha kumbuyo ndi kuigwiritsa ntchito mwanjira ina.
Zizindikiro zomwe zimabweretsa, zomwe zingaphatikizepo kupweteka, kupweteka, kugwedeza, kugwedezeka kwa magetsi, kuwotcha ndi / kapena kumverera kwa mapepala ndi singano kumadutsa mkono umodzi kapena mwendo umodzi, amatchedwa radiculopathy .
Kaŵirikaŵiri kusokonezeka ndi sciatica, radiculopathy amatanthauza zizindikiro zomwe tatchula pamwambazi zokhudzana ndi kukhumudwa kapena kupanikizika pamphuno wa mitsempha ya msana ndi dongosolo lomwe liri pafupi lomwe silingakhalepo.
Tawonani kuti radiculopathy ndi yeniyeni yeniyeni yeniyeni yomwe imayambitsa zizindikiro izi, pamene sciatica, yomwe imatanthawuza zizindikiro zomwezo, zingayambidwe ndi zinthu zingapo zomwe zimaphatikizidwa koma sizingatheke ku radiculopathy.
Zimayambitsa Kuponderezana ndi Ma Radiculopathy
Dothi la herniated limapezeka pamene mkati mwake mwadontho (wotchedwa nucleus pulposus) imathawira panja kudzera mwa misozi kapena dzenje m'matumbo olimba omwe nthawi zambiri amakhala nawo. Kawirikawiri, koma osati nthawi zonse, "zinthu" zapakatikatikati za mitsempha yapafupi, zimakakamiza.
Pankhani ya nyamakazi yamtsempha (yomwe imaphatikizana ndi matenda a msana ndi spinal stenosis) mafupa amapanga mawonekedwe opitirira nthawi, nthawi zambiri, ngati kuvomereza kuvulaza pamtengowo kungayambitsenso mitsempha yamtsempha ndipo imayambitsa zizindikiro za radiculopathy .
Ngati muli ndi zizindikiro izi, onani dokotala mwamsanga.
