Ƙari na Farko da Yawan Ƙari
Maganin da ke da mahimmanci shine jerin ƙananan ƙwayoyin tsohuwar ƙwayar tsohuwar ƙwayar cuta wadda take a kowane gefen ɓangaren kashin baya wanda ya zama kashi na biyu na tsokoki mai zurfi. Haɗuwa da 3 layers total, da tsokoki mai zurfi tsokoki suna da ake kira taro mai zurfi. Duk da haka wani suna don wannan rukuni shine Layer transversospinal.
Sakamakon : Ƙarƙashin ƙananan ƙwayoyin baya
Sama da tsaka-tsalle mai zurfi (zurfi) mai tsallewa na baya shine Layer. An kuma san sanannen Layer a matsayin tsokoki masu tsantsa ko kuma "ƙananan halayen kwalliya," ko kuma kawai tsokoki.
Abubuwan da suka shafi: Ƙungiya mai layi
Komawa ga multifidus. Wannan tsoka yana ƙaddamar da tsawon lokaci zuwa sama da yawa daga cikin kashin baya kuma yana da sassa 4: Cervical (wuyansa), thoracic (daidai daidai da na sama da tsakiyar yankin baya), lumbar (kawan baya) da kuma sacral (daidai da sacrum, wanda ke ƙasa low baya.)
A magungunan mahaifa, thoracic da yankunan lumbar, daya daga cikin multifidus ya rataye a kan hanyoyin tafiyar da kwayar cutar ta tsakiya, kuma ɗayan zuwa tsari mai sassauci a kan kwayoyin vertebra 2-4.
Cunkoson juyawa sune kari na kashi wanda ya fito daga jiki na vertebra a kowane gefe. Hakazalika da tafiyar matakai, ƙwayoyin motsa jiki sune kashi na kashi wanda ya fito daga baya na jikin kwayar.
Aikace-aikacen samar da wuraren da aka haɗe don tsokoki kamar multifidus da sauransu.
A cikin wadannan yankuna na ƙwayar mahaifa, thoracic da lumbar, tsoka yana tsaka tsakanin C-4 zuwa L-5. Yana da kauri a cikin goshin lumbar.
A sacrum , multifidus ya samo asali ne a bayan wannan kashi mai siffar triangular. Har ila yau yana samo asali ne a kan tsakiyar tsakiya (yana fuskantar tsakiyar bayan baya amma daga waje) surface na kashin baya na baya.
Hakazalika (amma ba kamar yadda) matakan da aka tattauna a sama ba, ƙananan halayen iliac ne mafi girma wanda ya fito daga saman ɓangaren baya na ɓangaren ku. Yana fuskantar fuska zuwa kashin ka. Har ila yau, multifidus yana samo asali ne daga jinginarku na sacroiliac. Sashin jiki na muscle mutifidus ya rataye a kan hanyoyin tafiyar da kwayar halitta a sama da shi.
Multifidus Muscle Roles
Kamar yadda sunan yana nuna, mahimmanci na raƙuman tsohuwar ƙwayar baya - wanda multifidus daya shine - shine a fadada baya, wanda yake da mahimmanci wajen yin motsi. Wadannan tsokoki suna taimakawa wajen karkatar da hanzari (juya) da juyawa (aka karkata.) Lokacin da bangarori biyu na kwangila (da kuma multifidus), sakamakon shine ƙaddamarwa. Lokacin da guda ɗaya ne ke yin kwangila a gefe kuma suna motsa motsi.
Amma multifidus kuma yana tabbatar da ƙwaƙwalwa kamar yadda motsi ya motsa. Ana tsammanin cewa zane-zane na multifidus yana ƙaddamar da shi tare da ƙarin ƙarfi.
Multifidus ƙarfin ya kasance batun wasu bincike mai ban sha'awa a cikin 'yan shekarun nan. Masu bincike sun dubi nau'in zarutun da ke dauke da wannan ƙananan tsoka - da kuma hanyar da waɗannan nau'in fiber suke taimakawa wajen farfadowa daga kashin baya.
McDonald, et. al rahoto game da irin wannan binciken a cikin bita: "The lumbar multifidus: Shin shaida nuna goyon baya ga bangaskiya?" Sun ce wani mai bincike ya gano cewa multifidus yana bada kimanin 2/3 na girman kai a haɗin L4 / L5 intervertebral. McDonald da ƙungiyarsa sun ambaci wasu binciken da ke nuna cewa haɗin gwiwar multifidus yana sarrafa motsi na kwakwalwan baya baya, kuma yana ƙaruwa (sabili da haka kwanciyar hankali a) raunuka masu rauni.
Bugu da ari, masana suna rarraba nau'in fiber multifidus ta yadudduka. Mafi zurfin Layer, suna bayar da shawara, yana ba da ƙarfi da kwanciyar hankali fiye da yadda ake yi da yadudduka.
Ɗaya daga cikin dalili da aka ambata a wannan ya haɗa da cewa zurfin mai zurfi ne kawai yana da kashi 2 na sassan layi (kamar yadda ya saba da 4 tare da sauran layer). Sakamakon "yawon shakatawa" mafi zurfi na zurfi mai zurfi na multifidus yana nufin cewa lokacin da kwangilar muscle ya taimaka wajen kara motsa jiki a cikin haɗin ƙwalji wanda yana rinjayar - amma ƙananan juyawa - idan aka kwatanta da sauran tsofaffin ƙwayoyin ƙarewa (ciki har da ƙananan yadudduka na multifidus kanta.)
Wani dalili shine mafi zurfin Layer na tsoka mai ƙarfi wanda ya ba da ƙarfin karfi shi ne ya sa ya zama "co-kwangila" tare da tsoka mai ciki na ciki - gaba daya a ciki. An lura da tsokoki don taimakawa ga lafiyar ƙwayar asali kuma sau da yawa suna taka muhimmiyar rawa a shirye-shiryen motsa jiki na gida wanda aka ba da marasa lafiya a cikin jiki.
