Isandiso Sempindelo Nokuningi Kakhulu
Imisipha ye-multifidus iyinhlanganisela yezinhlanzi ezincane, eziyisigxathu ezinamahlombe ezingxenyeni ezinhlangothini zomgogodla owenza isiphakamiso sesibili semisipha ejulile emuva. Ehlanganiswe izingqimba ezingu-3, imisipha ejulile emuva ibizwa ngokuthi i-layer yangaphakathi. Kanti elinye igama lale qembu liyingqimba ye-transversospinal.

Ngaphezulu kwezingqimba zangasese ezishintshayo (okujulile) zezingxenyeni zangemuva ungqimba olungenasisekelo. Isendlalelo esingenasici siyaziwa nangokuthi imisipha e-extrinsic noma i- "spinae erector," noma nje imisipha yomzimba.

Buyela ku-multifidus. Le misipha ihamba ngokulinganisa phansi kakhulu komgogodla futhi inezingxenye ezingu-4: Isibeletho (intamo), i-thoracic (ehambelana cishe nezindaweni ezingenhla nangasemuva), i-lumbar (ephansi emuva) ne-sacral (ehambisana ne-sacrum, engaphansi kwe-sacrum yakho phansi emuva.)
Emiphakathini yomlomo wesibeletho, i-thoracic kanye ne-lumbar, ukuphela komunye we-multitifidus kufaka izinqubo ezithintekayo ze-vertebra yomgogodla, enye enye inqubo ye-spinous kumazinga angu-2-4 ama-vertebra aphezulu.
Izinqubo eziguquguqukayo yizandiso zethambo ezivela emzimbeni we-vertebra ngakolunye uhlangothi. Ngokufanayo nezinqubo eziguquguqukayo, izinqubo ze-spinous ziyi-bone of bone ezivela ngemuva komzimba we-vertebral.
Izinqubo zinikeza ama-attachment sites for muscles njenge-multitifidus nabanye.
Kulezi zifunda ezihlangene zomlomo wesibeletho, i-thoracic ne-lumbar, imisipha ihamba phakathi kuka-C-4 kuya ku-L-5. Ibukhulu kakhulu emgodleni we-lumbar.
E- sacrum , i-multifidus ivela ngemuva kwalesi sithanga esenziwe ngunxantathu. Iphinde ivela kumphakathi (obhekene nendawo yangasemuva kunokuba ubheke ngaphandle) ebusweni bakho obuphezulu obuphezulu be-iliac umgogodla.
Ngokufanayo (kodwa hhayi okufanayo) nezinqubo ezikhulunywe ngenhla, umgogodla we-aliac ophakeme ophakeme ngemva kokuhamba komzimba uyisisindo sethanga esivela phezulu kwesigxathu se-hip bone. Ibheke ngaphakathi ngaphakathi kwe-sacrum bone yakho. I-multitifidus ivela futhi emigqeni yakho ye-sacroiliac. Ingxenye ye-sacral ye-mustifidus muscle ihlanganisa izinqubo ze-vertebrae ezingaphezu kwayo.

Imithwalo yemisipha yama-Multifidus
Njengoba igama libonisa ukuthi, indima ejwayelekile yemisipha yokudlulela emuva - leyo i-multifidus eyodwa - ukukhulisa emuva, okufana nokudala ukunyakaza. Lezi zinhlanzi zifaka isandla ekuguqeni okuhlangene (ukuguqula) nokujikeleza (aka ukuphazamisa.) Uma izinhlangothi zombili ze-extensors (ne-multifidus) inkontileka, umphumela ubuyiselwa emuva. Uma kuphela izinkontileka ezilodwa kuphela ohlangothini oluhambisana nokuguqa nokujikeleza okukwenziwayo.
Kodwa i-multitifidus ibuye iqinise ama-vertebrae njengoba umgogodla uhamba. Kucatshangwa ukuthi umklamo oyingqayizivele we-multifidus uwubeke ngamandla amakhulu.
Amandla we-Multifidus abelokhu ehlolisiswa ngocwaningo oluthakazelisayo eminyakeni yamuva. Abaphenyi babheke izinhlobo zezintambo ezibandakanya le misipha encane - futhi indlela lezi zindlela ze-fiber ezenza ngayo ukuqina komgogodla.
McDonald, et. ukubika ngezifundo eziningana ezinjalo ekubuyekezweni kwabo: "I-lumbar multifidus: Ingabe ubufakazi busekela izinkolelo zemitholampilo?" Bathi omunye umcwaningi wathola ukuthi i-multifidus inikeza mayelana no-2/3 kokuqina kohlangothini lwe-intervertebral L4 / L5. UMcDonald kanye neqembu lakhe bakhulume ezinye izifundo ezibonisa ukuthi ukuqhuma kwe-multifidus kulawula ukunyakaza kwamajoyini angenalutho angenalutho, futhi kwandisa ukuqina (futhi ngenxa yalokho ukuqina) ekuhlangenwe nakho okuphansi okulimazayo.
Ngaphezu kwalokho, ochwepheshe bahlukanisa izinhlobo ze-multifidus fiber ngezindlela. Isendlalelo esijulile, basikisela, sinikeza amandla amaningi nokuzinza emgodleni kunokuba wenze izendlalelo ezingenasici.
Esinye isizathu esishiwo ngalokhu kufaka hlangana iqiniso lokuthi uhlaka olujulile luhlukanisa izingxenye ezimbili ze-vertebral (ngokungafani no-4 nezinye izendlalelo). "Ukuhamba" okufishane kocansi olujulile lwe-multifidus kusho ukuthi uma izivumelwano zesikhumba, kubangele ukunyakaza okuningi kohlobo lomgogodla kuthinta - kodwa ukushintshanisa okuncane - kuqhathaniswa nezinye izinthambo ezidlulayo emuva (kufaka phakathi izingqimba ezingaphezulu we-multitifidus ngokwayo.)
Esinye isizathu isendlalelo esijulile semisipha ye-multitifidus sinikeza amandla amaningi ukuthi ukuthi "i-co-contract" ne-deep muscle yomzimba ngaphambili - isisu esiswini. Imisipha emzimbeni iyaziwa ngokufaka isandla kwabo ekuzinzeni umgogodla futhi idlale indima ebalulekile ezinhlelweni zokuzivocavoca ekhaya ezinikezwa iziguli ezithinta izifo emithini yokwelashwa.
