Mphepete yam'mimba ndi malo a msana wam'mimba omwe ali ndi kumbuyo kwenikweni.
Nthenda yamtunduwu imapangidwa ndi 5 vertebrae . Zilonda za Lumbar zimatchulidwa ndi 'L,' zimakonzekera nambala yodziwika. Chiwerengerocho chimasonyeza mlingo wa mphalapala womwe umapezeka kuti vertebra ilipo. Chigawo chilichonse cha msana (ie, chiberekero, thoracic, lumbar ndi sacral) ali ndi ziwerengero zawo; mafupa a mphulupulu zamtunduwu amawerengeka kuyambira L-1 mpaka L-5.
Pansi pa mphuno ya lumbar ndi sacrum ndi pansipa, ndi tailbone, kapena coccyx. Chiphalaphala ndi fupa lomaliza la msana.
Mofanana ndi pafupifupi mtundu uliwonse wa vertebrae wamtsempha, fupa pamphuno ya lumbar imapangidwa kutsogolo ndi kumbuyo "zinthu." Kutsogolo, thupi lopweteka limapereka chithandizo pogwiritsa ntchito pang'onopang'ono pamwamba pa fupa pansipa, ndi pothandizira imodzi pamwambapa. (Lumbar vertebra ya 5 imakhala pamwamba pa sacrum bone ku sacral base.)
Mphete ya bony yomwe ili ndi zidutswa zingapo ndi madera angapo amamatira ku thupi lakumbuyo kumbuyo. Zipangizozi zimapanga ntchito zambiri, kuchokera kumalo osungunula omwe amagwiritsa ntchito mitsempha ndi minofu kuti apange mizere yomwe mumtsinje wa msana ndi mizu ya msana imadutsa, ndikupanga ziwalo zomwe zimathandiza kusunga umphumphu wowongoka.
Lumbar Lordosis
Gawo lirilonse la msana ndi lopindika, ndipo dera la lumbar silimodzimodzi. Mphepete mwachitsulo njira yowonjezera mu msana kuti muthandize kupereka zowonjezera ndi kuthandizira kusuntha.
Mu khola la khosi (khosi) ndi mitsempha ya lumbar, mphutsi imapita kutsogolo kwa thupi pamene muyang'ana pambali. Izi zimatchedwa lordosis.
A lordosis ali ndi digiri ya ma curve omwe si owonjezera, koma akatswiri samadziwa chomwe chiyeso icho, ndendende.
Mavuto Amodzi
Nthenda yam'mimbayi ndi malo ambiri ovulala kumbuyo ndi chikhalidwe.
Izi zimachokera ku vuto la disc kuti likhale lachilendo komanso nyamakazi yamtsempha, kuphatikizapo zambiri. M'munsimu muli mndandanda waung'ono (ngakhale wosakwanira) mndandanda wa zovuta zokhudzana ndi malo otsika:
- Matendawa amapezeka pamene mafupa a msana akupita patsogolo, pafupi ndi fupa liri pansi pake. Ndi mtundu wa msinkhu wosasunthika (onani m'munsimu) ndipo ndipang'onopang'ono ya spondylolysis, komanso vuto lapiritsi kapena kuvulala.
- Nthendayi yokhudzana ndi matendawa ndiyomwe imayambitsa matenda a mitsempha omwe angathe kuchitika kumadera aliwonse a msana, kuphatikizapo malo amodzi.
- Spurs ndi nyamakazi ina yokhudzana ndi msana.
- Mphuno yobwerera ndi mavitamini omwe amayenda kupyolera mu fascia kumbuyo; kawiri kaŵirikaŵiri amadziwika bwinobwino.
- Kusakhazikika kwa msana , komwe kungayambitsidwe ndi zinthu zingapo, kawirikawiri kumadzetsa kusowa kwokhoza kuthandizira kulemera kwanu. Zimakhalapo pamene mavuto amodzi kapena atatu mwa msana "apansi" amapezeka.
