Sartorius: yayo indawo, umsebenzi, innervation

imisipha ithanga bohlulwa babe ngamaqela amathathu. Iqela akuyona ukugoba, emva - extensors, kwaye linoxanduva lokuzisa nomlenze medial. Baye awachukumise nobude, ebambeleyo ekhankanyiweyo inyonga nedolo joint ekwenzeni umsebenzi static kunye neguquguqukayo xa uhambisa okanye bemi. Kanye izihlunu zangasese, imicu kwezihlunu le nemilenze ukufikelela kuphuhliso ngokuxhomekeke aokusetyenziswa ezinxulumene bipedalism.

Sartorius: indawo

Le imisipha (musculus sartorius) iyeyona inde phakathi Imicu izihlunu umzimba. Inxalenye proximal iqhotyoshelwe kwalapho iliac ongentla phambi womlenze obliquely uyehla. A msebenzi kukuba ngoxa wawusalathiswa ngaphandle ngaphakathi kwaye yenza uhlobo yejelo gunterovom igumbi phezu kwemithambo femoral, luvo saphenous kunye umthambo.

Kwinxalenye esezantsi sartorius ethangeni oko phantse nkqo kwaye inqumla condyle medial. Ummandla distal igcina imicu luqalise ukuya ifascia emlenzeni.

features sartorius

Umsipha ifumana igama layo ngenxa inxaxheba iintshukumo entlanganweni womlenze, apho umntu ukufumana zalezo ume imilenze bawela (elithi "sartor" kuthetha ukuba "yenza").

Musculus sartorius imicu, ndawonye imicu kwezihlunu ezingcakacileyo, imisipha semitendinosus benza ipleyiti ezinezikhondo ezibunxantathu, leyo ibizwa ngokuba 'iinyawo unomyayi wakhe ".

Kubalulekile ukuphawula ukuba sartorius ubhekisela kwimicu ezinako ukutshintsha kakhulu ngoxa kuncitshiswa ubude bayo. Ngokufanayo, ipropati usenayo i ngqo umsipha esiswini, kwakunye obhityileyo kunye semitendinosus. A umsebenzi osemqoka Imicu sartorius kukuba aziyo iinyanda ezahlukahlukeneyo. Oku kukhokelela yokuba leesynapse zabo neuromuscular luphawulwa lokusasaza engaqhelekanga. Ukongeza, le sartorius lungohlulwa lube constriction ezimbini ezinxuseneyo okanye phambana isisu tendinous, nto leyo ekhokelela yokuzahlula yayo ibe ongentla inxenye osezantsi.

Kwakhona Kubalulekile ukuphawula ukuba esihlunwini ibonakala ngokucacileyo ngaphantsi kwesikhumba, ukuba begoba ihleza okanye athathe, yaye xa ukuqondisa umzantsi womlenze. Ukongeza, ukuba iviwe kakuhle kwindawo ethangeni.

Indima sartorius

Musculus sartorius ababandakanyekayo hip flexion nokuxhwilwa, yaye le imisipha inoxanduva intshukumo ngaphandle, kunokuba izibilini. Xa ujikelezo lwangaphakathi kasikrobana ayikho inxaxheba. Xa uzama ukwenza ukujikeleza yangaphandle isebenza okanye kwaphela, okanye ukwenza kangangoko ezingaphelelanga. Endaweni ehleli le sartorius ukujikeleza lwangaphandle ilandelwa yi umsebenzi ngomlinganiselo. Xa edolweni imisipha ifayibha kwezihlunu izibandakanye ngakumbi, ukuba ngaxeshanye kuqhuba flexion hip.

Kufuneka kuqatshelwe ukuba iimviwo EMG watyhila ukuba sartorius esebenzayo emdlalweni yevoli okanye yomnyazi. Ngaloo sartorius musculus kwicala elisekhohlo nomdla kakhulu inxaxheba zonke iintshukumo esandleni sasekunene (umzekelo, ngexesha umdlalo yentenetya), kwaye kananjalo usebenza kwi ukuhamba, ukutsiba okanye ukhwele ibhayisekile.

Ngenxa yoko, kunye nezinye Imicu izihlunu sartorius kwezihlunu, umsebenzi ekungabalwa intshukumo yalityatya ephantsi, hip ubonelela ujika ngaphandle, kwaye linoxanduva ayeguqa umlenze.

Innervation sartorius

Kuba innervation musculus sartorius luvo onoxanduva femoral, nto leyo equka 2-4 iingcanjana. Amasebe eli-luvo innervate ulusu womlenze ephakathi kunye nommandla medial yomlenze ephantsi ukuya kwikona ngeenyawo.

Xa utshintsho zophendlo lwezifo ze-luvo femoral uyakwazi ukuphuhlisa paresis okanye ukushwabana, ngokunjalo kunciphisa ithoni imicu ingqondo. Elide ukukhubazeka kwezihlunu ikhokelela yoma kunye ukubonakala contractures, ezo zihamba ngokwamathambo engaqhelekanga nokubekwa ngokusebenzisa ukusebenza olunempilo izihlunu-abamelene.

Ukongeza, kusenokubakho zemizwa ngohlobo paresthesias, gipostezii okanye Ukubulawa ngokupheleleyo. Maxa wambi, phezu koko, ebhalwe utshintsho uvakalelo lohlobo hyperpathia xa izigulane kufuneka ukutshisa uphawu iintlungu leyo ayikwazi ukususwa analgesics.

Kwimeko zokugxojwa innervation sartorius ukuhamba ngokuqhelekileyo kwaphulwa, ukuba kunganxulunyaniswa ukuntsonkotha kwesebe flexion esezantsi kasikrobana, okanye ukungakwazi ukuze uphakamise kakuhle esinqeni.

Kufuneka wenze ntoni xa umonakalo sartorius?

luvo femoral neuropathy, leyo kukwaphulwa contractility le sartorius, amaxesha amaninzi emva kotyando kwindawo zangasese okanye ethangeni. Isizathu nazo abe enyelisa okanye ucinezelo ngqo imicu kwezihlunu. Kubalulekile kwakhona ukuba sikhankanye ukuba neuropathy kunokwenzeka abanesifo seswekile sinwenwa.

Ukuba zimpawu umonakalo enokuphazamisa imithambo-luvo femoral ekhatshwa flexion alo mlenze esezantsi, kufuneka ujonge kwi-luvo. Uya kuqhuba uviwo luvo, electrotherapy, ukuba kuyimfuneko, amisele ukuba CT scan, i-MRI bendawo retroperitoneal kunye nonyango olufanelekileyo.

Xa ezonakeleyo sartorius ethangeni unyango unyango olusebenzayo. Kwakhona sisebenzisa le ndlela zokuphumla, bazolulela imicu izihlunu abachaphazelekayo, femoral luvo kwafa nokulungiswa ezigqithisileyo lolwandiso umlenze kunye notshintsho ubude nomlenze ephantsi ngenxa kuphuhliso contractures. Kubalulekile ukuphawula ukuba ukufumana iziphumo ezidibanisayo kunokwenzeka kuphela ulungiso zezihlunu, ezo zinonxulumano kummandla kwintshabalalo.
