Semimembranosus tsandanyama rorudyi; nzvimbo, mamiriro, zvokurwara

Chidya tsandanyama dzakapoteredza femur, zvichienderana urongwa vari rakakamurwa akawanda mapoka: Anterior, posterior uye medial. Rwemberi boka iri anokonzera pryamohozhdnie uye muviri kuswatura, hudyu zvakawedzerwa mu hudyu flexion uchingodzikira gumbo iri ibvi mapfundo.

Rwemberi boka ine zvinotevera tsandanyama:

• biceps;

• semitendinosus uye semimembranosus tsandanyama.

nzvimbo

Semimembranosus tsandanyama yaiva pasi pechidya semitendinosus. Kutanga muskulus semimembranosus (semimembranous tsandanyama) pamwe mudzira ndiro, iro unotora yose pamusoro mugove kuburikidza achabatanidza yokumusoro chikamu kusvika ischial tuberosity uye ipapo kunotangira achitevedza medial (yomukati) pamuuyo femur. The yokupedzisira (distal) semimembranosus tsandanyama mudzira uchiora pajinga mudzira kuda zvitatu danda Anoumba tsoka yakadzika rarira pane mumwe nomumwe pazvidya.

Mumwe tufts riri richengetwe kusvikira fascia anofukidza hamstrings, wechipiri - dzomunyika condyles tibial pfupa (tibia) ari makumbo ose, wechitatu zvakanaka ndatendeuka kuti rwemberi ibvi kwemajoini chikamu yehudyu posterior oblique shwashwa.

Apo tsandanyama mudzira iri rwakakamukana matanda akawanda dziri bursa (bursa muskulus semimembranosi) semimembranosus tsandanyama.

mabasa

Semimembranosus tsandanyama anoita dzinokosha mashandiro kuti zviite kwebasa ezasi konechnochti ari muhudyu uye ibvi majoini:

• Flexes amakumbo ibvi mapfundo.
• Kutenderera (kutenderera) munzvimbo dzakaderera gumbo pamwe pamabvi hwakakungwa (tsandanyama kunochengetedza synovial Kamudzira kubva kusunga, achidhonza mumwe Kamudzira pamusoro ibvi).
• Kuwedzera muhudyu mune hudyu mapfundo.
• Tonic tsandanyama.
• Kana tibia vari yakatarwa, ivo semimembranosus tsandanyama, pamwechete gluteus Maximus ndivo mhosva kuwedzera hunde.

Nutrition uye innervation

Zvinonzi unokupai Mweya semimembranosus tsandanyama tsinga kuti rinokomberedza yehudyu popliteal uye perforating tsinga.

tsandanyama innervation of tibial etsinga rinoitwa.

Semimembranosus tsandanyama chirwere

1. Kukuvara - Munotatamura madhigirii zvitatu zvakaoma kwazvo, kusanganisira kukwana uye kwakakwana atsamwira.

2. Tendinopathy - a zvokurwara kuti kunoratidzwa kurwadza nezvekufadza ari posteromedial zvikamu ibvi muhudyu, kuipa mushure murwere vachasimudza, pakupedzisira, uyewo ibvi flexion nemishonga. The kunonyanyisa marwadzo chinorondedzerwa muna mudzira insertions pamusoro posteromedial pemvura tibia zvishoma pazasi kumuganhu rwakashodoka. Pakati Kamudzira pamusoro pebvi muhudyu, ari medial gastrocnemius tsandanyama uye mudzira iri muhomwe, mukati izvo zvinogona kuva chirwere bursitis. Zvakakosha kuita differential chirwere kubva intra-articular pathologies. Semimembranosus tsandanyama tendinopathy kubatwa zvakafanana kune dzimwe nzvimbo kuti tendinopathy.

3. Insertsinit patsoka rarira raMwari kunoratidzwa muna kunowedzerwa zvokunze kutenderera kana kana iwe kuedza kutsausa mukati panguva ibvi yakamisirwa tibia (jimunasitikisi, nhabvu, Skiing). Clinical kuratidzwa: kuwedzera yemunyika kuzvimba, marwadzo panguva palpation, izvo yakakura kana kuedza kurega mupambare wake vakamanikidzwa womukati kutenderera chinzvimbo. The inonyanya kukuvara tsoka rarira vari pamwe kukuvara nedzimwe nhengo dzose ibvi pakudzikamisa. The differential chirwere chirwere ichi yaifanira pamwe womukati meniscus maronda (the posterior nyanga) uye bursitis ari unyanzvi.

4. Popliteal fossa chikofu (chikofu Becker) - iri kushoma munyika mucous bhegi semimembranosus uye gastrocnemius tsandanyama (kuvapo mabhegi yakadaro inowanikwa muna 60% vanhu utano uye haisi yakatsauka kubva ndozvakajairwa). Chikofu akaora kwakaratidzwa sezvo plotnoelastichnoy bundu iri repamusoro chikamu popliteal fossa, kuzvimba, kuwedzera kukura (nokuda compression zvinotora nzvimbo dzakapoteredza zvivako), kusanzwa, marwadzo uye kukamurwa inofamba. Most chikofu kechipiri chinovapo Somugumisiro pahombodo distension Urume mune chirwere kuzvimba ibvi muhudyu, kuva akasiyana etiology (rheumatism, tibhii, akasiyana-siyana kukuvara, osteoarthritis nevamwe).
