Zikhoza kukhala zomwe amayi anu adakuuzani, koma msana sikutanthauza kulunjika.
Chifukwa cha malo ake, msanawo umayenera kupanikizika, kulemera, ndi mphamvu kuchokera kuzipangidwe zomwe, poyerekeza, zimakhala zolemetsa komanso zolemetsa. Chitsanzo ndi pakhosi lanu, lomwe ndi fupa lalikulu lomwe mumphepete mwa msana.
Ndipo ngati kuti sizinali zovuta, monga gawo la ntchito yake, msanawo uyenera kuthandiza thupi lanu lonse kuti likhale labwino komanso liwiro.
Izi zimasinthidwa ndi kusungidwa ndi mpweya wa msana.
Tsitsi Lanu Ndilo Mmene Mphepo Yamagulu Amayendera
Mzere wa msana umapangidwa ndi 33 vertebrae. Zambiri mwachindunji zikukhalabe, ndipo motero zimathandizidwa ndi, "sacral base."
Mtsinje wa sacral ndiwo pamwamba pa fupa la sacrum , lomwe ndi mafupa atatu omwe ali pakati pa mafupa anu awiri kumbuyo. Thumba la sacrum limangozungulira pang'onopang'ono.
Pansi pa sacrum bone ndiwe mafupa ako, aka tailbone.
Ndipo pamene mungaganize za msana wam'mimba monga msana wanu, kwenikweni, uli mkatikati mwa thupi lanu - kuchoka pakatikati pa chigaza chanu mumtengo wanu kupita ku sacral. (Monga momwe tafotokozera mwatsatanetsatane, mungathe kumvetsetsanso njirayi mozungulira - mwachitsanzo, msana wa msana ukukwera kuchokera ku sacral base mpaka kudutsa thunthu kupita ku chigaza.)
Mzere wa msana umakhala ndi chingwe cha msana, chomwe ndi chinsinsi cha dongosolo loyamba la mitsempha.
Mphepete mwa msana umadutsa pakati pa phokoso la mafupa a msana (omwe amatchedwanso vertebrae) omwe amapanga mzere wa msana.
Malo owongoka a msana - monga pamene iwe ukhala kapena kuimirira - amatchedwa "malo" komanso / kapena "static spine". Kuchokera ku "malo" omwe "anatumizidwa" omwe anatomists amapanga miyeso ndikupanga zizindikiro zowonetsera zomwe ziri zachibadwa ndi zathanzi paziganizo zanu, ndi zomwe zikusowa kugwira ntchito.
Mphepete mu msana
Msanawo umagawidwa m'madera otsatirawa:
- Chiberekero (khosi), chomwe chiri ndi 7 vertebrae,
- Thoracic (kumtunda ndi kumbuyo), wopangidwa ndi ma vertebrae 12
- Lumbar (wotsika kumbuyo), wopangidwa ndi 5 (ndipo mwa anthu ena, 6) vertebrae
- Sacral (sacrum bone, yomwe ndi fupa limodzi la mafupa asanu limaphatikizana pamodzi)
- Coccyx (tailbone, yopangidwa ndi 4 yosakanizidwa mafupa.)
Mbali izi za pamphepete mwa msana zimagwirizana ndi mizere ya msana. Kawirikawiri, kokha, ma thoracic ndi lumbar curves amatha kuyankhulana, makamaka pamene kuyankhulana kumaperekedwa ndi madokotala ndi opaleshoni kwa anthu omwe si achipatala. Kulepheretsa kukamba nkhani za m'mphepete mwa msana kwa chiberekero, thoracic ndi lumbar ndichinthu chofala muzofalitsa.
Kutengedwera kwathunthu, mizere mu msana wamkulu imapanga mawonekedwe a "S" pamene muyang'ana thupi kuchokera kumbali. Kuchokera kumbali yowonekera, zina za mphutsi zikupita kutsogolo kutsogolo kwa thupi lanu ndi ena akubwerera kumbuyo. Malangizo a mliri uliwonse (ie kutsogolo kapena kumbuyo) amasintha kuchoka pamphepete kuti apite; Kusintha uku kukuthandizani kukhalabe ndi thupi komanso kukambirana mavuto anu.
Maina a Miyala
Ndipotu, makomowa amagawidwa molingana ndi momwe amachitira akamayang'ana msana (thupi) kuchokera kumbali.
Mawu omwe amamasulira khosi ndi mapiri otsika kumbuyo ndi lordosis. Mawu akuti thoracic ndi sacral mavoti ndi kyphosis. (Mwinamwake mwamva za kyphosis ngati vuto lachitukuko. Koma kwenikweni, kyphosis ndi dzina lenileni la mtundu wa mpikisano, ndipo pamene pali zochuluka kwambiri, mosasamala kanthu za dera lomwe liripo, mawuwo amakhala chilembo cha vuto kapena matenda a zachipatala. Mawu akuti lordosis amagwiritsidwa ntchito mofanana.
Wotchedwa koyamba, ma kyphotic curves (thoracic ndi sacral) alipo pomwe mukubadwa, palimodzi mukupanga mawonekedwe akuluakulu a C. Zina zimakula pamene mumatha kukweza mutu wanu (khola lachiberekero) ndikuphunzira kuyenda (lumbar curve.
Kusintha
Zigawo zosinthika pakati pa mapiri a msana zimatchedwa magulu. Mwachitsanzo, mgwirizano wa cervicothoracic ndi malo pakati pa vertibra yanu yachisanu ndi iwiri (ndi yotsiriza) yamtundu wanu ndi vertebra yanu yoyamba ya thoracic. Kugwiritsidwa ntchito kwa thoracolumbar ndi mbali ya kusintha kwa msana wa thoracic ndi msana wanu wam'mimba. Chifukwa misonkhanowo imaphatikizapo kusintha kayendedwe ka pakati pa mphindi imodzi ndi yotsatira, nthawi zina zimakhala zovuta kwambiri kuvala ndi kuvulaza mitundu ina.
Monga mukuonera, mazenera a msana ndi ofunikira komanso ovuta. Pachifukwa ichi, ndibwino kuti musayese msana, koma m'malo mofuna njira zowonjezeramo ziwalo zonse za thupi lanu. Izi zikhoza kuthandiza mitsempha yanu ya msana kuti igwire malo abwino kwambiri a kukhazikika bwino ndi kubwerera kwapweteka.
