Semimembranosus imisipha ethangeni: indawo, isakhiwo, zokugula

imisipha ethangeni ezizungezile kunawo wonke, kuye ilungiselelo zihlukaniswe amaqembu amaningana: anterior, posterior futhi medial. Iqembu ezingemuva unesibopho pryamohozhdnie nomzimba Ehlala, hip isandiso flexion hip nasemlenzeni aphansi emalungeni kwedolo.

Iqembu ezingemuva siqukethe imisipha ezilandelayo:

• biceps;

• imisipha semitendinosus futhi semimembranosus.

indawo

imisipha Semimembranosus itholakala ngaphansi semitendinosus ethangeni. Ukuqala muskulus semimembranosus (imisipha semimembranous) nge umsipha ipuleti, okuyindawo ehlanganisa yonke ingxenye ephezulu axube engxenyeni engenhla kuya tuberosity ischial bese yehla eduze medial (kwangaphakathi) emaphethelweni kunawo wonke. Yokugcina (distal) semimembranosus imisipha umsipha ubola ezansi umsipha okunamathiselwe ku ezintathu ugongolo ukwakha izinyawo likhale ezijulile ku ngamunye emathangeni.

Omunye tufts is kuvikelwe kuya fascia ohlanganisa hamstrings, kwesibili - le condyles yangaphakathi ithambo tibial (tibia) ku imilenze yomibili, eyesithathu kahle kokuba waphendukela ezingemuva amadolo ingxenye ahlangene posterior ethangeni umsipha etshekile.

Lapho umsipha imisipha ihlukaniselwe imishayo eziningana elise Bursa (Bursa muskulus semimembranosi) imisipha semimembranosus.

imisebenzi

imisipha Semimembranosus wenza eziningi imisebenzi ezibalulekile lula ukuhamba konechnochti aphansi e-hip kanye kwamajoyinti:

• Flexes umlenze emalungeni kwedolo.
• Ukuzungelezisa (ukuzungeza) ku umlenze esiphansi kanye amadolo bent (imisipha ivikela ulwelwesi lwamalunga kusukela pinching, edonsa capsule ka kwedolo).
• Ukwelulwa okhalweni emalungeni hip.
• imisipha Tonic.
• Uma tibia benzelwe, imisipha semimembranosus, kanye maximus gluteus banesibopho isandiso isiqu.

Ukudla innervation

It ufakela semimembranosus imisipha Umthambo ezungeza senyonga popliteal futhi perforating Umthambo.

imisipha innervation we emsipheni tibial wenziwa.

Semimembranosus imisipha isifo

1. Ukulimala - esisuka degrees ezintathu kobukhulu, kuhlanganise ukudabuka ngokwengxenye futhi ephelele.

2. Tendinopathy - a zokugula kubonakale emizweni ubuhlungu izingxenye posteromedial we ngokuhlanganyela amadolo, sibi emva lift kummango, ngokuhamba kwesikhathi, kanye edolweni flexion ukumelana. Ubuhlungu esiphezulu ichazwa okufakiwe umsipha phezu posteromedial we tibia kancane ngezansi umngcele ngokuhlanganyela. Phakathi capsule we ngokuhlanganyela amadolo, le medial gastrocnemius imisipha kanye umsipha itholakala isikhwama, ingaphakathi okungase ukuthuthukisa bursitis ezingamahlalakhona. Kuyadingeka ukuba afeze umehluko ukuxilongwa naphakathi-articular pathologies. Semimembranosus imisipha tendinopathy aphathwe ngendlela efanayo nezinye izindawo tendinopathy.

3. Insertsinit ezinyaweni likhale sika kubonakala sithuthukiswe Ukujikeleza zangaphandle noma uma uzama ukuvula owangaphakathi ngesikhathi edolweni tibia esinqunyiwe (yokuzijwayeza, ibhola, Ukushushuluza). ukubonakaliswa Clinical: okwandisa ukuvuvukala zendawo, ubuhlungu ngesikhathi palpation, okuyinto iyakhula lapho sizama ukuba bahoxe shin wamxosha yangaphakathi Ukujikeleza isikhundla. Umonakalo ezivame kakhulu izinyawo likhale sika ehlangana umonakalo kwezinye izakhiwo kwedolo eliletha ukuthula. Imiphumela yaloku kuhlola okungenhla umehluko yalesi sifo kumele kwenziwe nge yangaphakathi meniscus izilonda (uphondo posterior) kanye bursitis ubuciko.

4. Popliteal fossa simila (simila Becker) - kuyinto ukuvuvukala kule lwamafinyila isikhwama semimembranosus futhi gastrocnemius kwemisipha (ukuba khona izikhwama enjalo itholakala 60% abantu abayimiqemane futhi akuyona ukuphambuka kusuka kuyinsakavukela). Simila emtholampilo obonakala njengenhlangano plotnoelastichnoy isimila engxenyeni engenhla fossa popliteal, ukuvuvukala, okwandisa ngobukhulu (ngenxa yokucinana ebanjwa izakhiwo ezizungezile), ukungakhululeki, ubuhlungu futhi komkhawulo motion. simila Iningi okwesibili kuphakama ngenxa uketshezi isikhwama distension e ukuvuvukala njalo ilunga amadolo, kokuba omsakazo ezahlukene (rheumatism, isifo sofuba, ezihlukahlukene ukulimala, osteoarthritis abanye).
