Semimembranosus ethangeni imisipha: indawo, isakhiwo, zokugula

izihlunu ithanga ezingqonge yifemur, kuxhomekeka kwilungiselelo bohlulwa babe ngamaqela ezininzi: cipande, ngomva kunye medial. Iqela diff unoxanduva pryamohozhdnie nokolula umzimba, ulwandiso hip kwi flexion inyonga umzantsi womlenze kwamalunga idolo.

Iqela ngasemva ibandakanya izihlunu zilandelayo:

• zomfana;

• imisipha semitendinosus kunye semimembranosus.

indawo

umsipha Semimembranosus ibekwe phantsi semitendinosus ethangeni. Ukuqala muskulus semimembranosus (umsipha semimembranous) nge plate imicu, eliquka yonke isabelo phezulu ngokufaka inxalenye ephezulu ukuya tuberosity ischial bese yehla ecaleni medial (ngaphakathi) ngohlangothi yifemur. Okugqibela (distal) imicu semimembranosus kwezihlunu abole kwi imicu attachment ephantsi kwibhim ezintathu ukwakha iinyawo crow enzonzobila ngasinye kwamathanga.

Enye besusa lukhuselekile ukuba ifascia nolwenzelwa hamstrings, le yesibini - le condyles lwangaphakathi ithambo tibial (lesiquluba) omabini imilenze, nowesithathu kakuhle ziyajikiswa ngasemva edolweni inxalenye odibeneyo ngomva wethanga lungu elibhalwe ngokumileyo.

Apho imicu kwezihlunu liyacandeka ibe ngamaplanga ezininzi ibekwe Bursa (Bursa muskulus semimembranosi) izihlunu semimembranosus.

imisebenzi

umsipha Semimembranosus yenza iqela lemisebenzi ebalulekileyo ukuze kube lula ukuhamba konechnochti ephantsi inyonga nedolo amalungu:

• Flexes umlenze kwamalunga idolo.
• Ujikelezo (ukujikeleza) kulo umzantsi womlenze kunye ugobe amadolo (kwezihlunu sikhusela synovia ukusuka ngozipho, etsala capsule le idolo).
• Ukwandiswa esinqeni kwamalunga hip.
• umsipha tonic.
• Ukuba lesiquluba ayinakutshintshwa, umsipha semimembranosus, kunye maximus gluteus banoxanduva ukwandiswa buti.

Nutrition kunye innervation

Oku kunibonelela kwemithambo kwezihlunu semimembranosus ukuba encircles umlenze, popliteal kunye Umthambo perforating.

izihlunu innervation ye-luvo tibial yenziwa.

isifo imisipha Semimembranosus

1. Ukwenzakala - ngokolula degrees ezintathu ubukhulu, kuquka komsipha oluphakathi kunye epheleleyo.

2. Tendinopathy - a oko kuboniswa ubuhlungu kwiindawo posteromedial welungu idolo, mbi emva ilifti kwiziphambuka, ekugqibeleni, kwakunye ukunganyangeki idolo flexion ngezifo. Le ntlungu eliphezulu uchazwa kwala imicu kumphezulu posteromedial le lesiquluba ngezantsi kancinci umda ehlangeneyo. Va philisi welungu idolo, lo gastrocnemius kwezihlunu medial kunye imicu ifumaneka ibhegi, ngaphakathi kwayo ukuphuhlisa bursitis ezigulo ezondeleyo. Kuyimfuneko ukuba enze ezohlukileyo ekufumaniseni ezimbi intra-articular. Semimembranosus tendinopathy kwemisipha uphathwa ngokufanayo kwezinye iisayithi ze tendinopathy.

3. Insertsinit ezinyaweni unomyayi wakhe esibonakaliswa ujikelezo oluphuculweyo zangaphandle okanye xa uzama ukuvula ngaphakathi kwi edolweni lesiquluba ezisisigxina (imithambo, ekhatywayo, Ukuskiya). obubonakala Clinical: ukwandisa iindumbisa zasekuhlaleni, iintlungu ngexesha Ngokucofa, leyo ziyanyuswa xa uzama ukuba lirhoxe bembande yakhe kwanyanzeleka kwindawo ujikelezo lwangaphakathi. Umonakalo kakhulu ezifanayo iinyawo ingekalili zinikwa kudityaniswe umonakalo nezinye izakhiwo ze idolo ozinzileyo. Uxilongo mahluko kwesi sifo kufuneka wenziwe kunye izilonda lwangaphakathi meniscus (sesigodlo ngomva) kunye bursitis kwimizobo.

4. Popliteal fossa cyst (cyst Becker) - yinkqubo yokukrala kwi semimembranosus ebhegini uxakaxa kunye gastrocnemius kwezihlunu (ubukho kwiingxowa ezinjalo lufumaneka-60% yabantu esempilweni kwaye akukho ukutenxa kumgaqo). Cyst ngokwezonyango wabonakalaliswa njengoko plotnoelastichnoy ithumba kwi kwinxalenye engentla fossa popliteal, ukudumba, ukwandisa ubukhulu (ngenxa ucinezelo leyo ethatha izakhiwo indawo engqonge), ubuhlungu, iintlungu emthwalweni sentshukumo. Uninzi cyst secondarily kuvela njengesiphumo wengxowa distension ulwelo xa ukudumba ezingapheliyo welungu idolo, ukuba umyalezo ezahlukeneyo (rheumatism, isifo sephepha, iintlobo yokwenzakala, osteoarthritis kunye nabanye).
