Sartorius: zake malo, ntchito, innervation

minofu ntchafu anawagawa m'magulu atatu. Gulu kutsogolo ndi flexors, kumbuyo - extensors, ndipo ndi udindo kubweretsa ntchafu medial. Iwo ndi kulemera ndithu ndi kutalika, kuchita m'chiuno ndipo bondo olowa kuchita ntchito malo amodzi ndi zazikulu pamene kusuntha kapena kuima. Monga minofu m'chiuno, Ulusi minofu ya miyendo m'munsi kufika chitukuko pazipita kuti zikhoza kugwirizana ndi bipedalism.

Sartorius: location

minofu izi (musculus sartorius) ndi yaitali pakati ulusi minofu ya thupi. Mbali proximal amamangiriridwa chapamwamba iliac msana ndi pamaso pa ntchafu obliquely kunsi wotsika. Mbali A ndiye kuti pamene imatsogoleredwa kuchokera kunja mkati ndi ndipamene mtundu wa njira gunterovom m'chipinda chotetezeka pa womwe ndi mtsinje femoral, mitsempha saphenous ndi mtsempha.

Mu mmunsi mwa ntchafu sartorius zimangokhala ofukula ndi intersects ndi condyle medial. Dera wapotalikira izo zikutsiriza tendon kukonde- kwa fascia wa mwendo.

NKHANI sartorius

minofu afika dzina lake chifukwa cha nawo m'magulu a m'chiuno limodzi mu umene munthu angathe kukhala telala imani miyendo anawoloka (mawu "sartor" anamasuliridwa kuti "telala").

Musculus sartorius tendon, pamodzi ndi ulusi woonda ndi tendons semitendinosus minofu kupanga fibrous triangular mbale wotchedwa "khwangwala mapazi".

Dziwani kuti sartorius amatanthauza ulusi okhoza kwambiri kusintha pamene kuchepetsa kutalika kwake. Mofananamo, chuma adakali ndi mwachindunji m'mimba minofu, komanso woonda ndi semitendinosus. Mbali A wa ulusi sartorius ndi kuti iwo alibe kupanga mitolo osiyana. Zimenezi zimabweretsa chakuti synapses awo neuromuscular yodziwika ndi kugawa yachilendo. Komanso, sartorius angathe kugawidwa mmagawo awiri kufanana kapena intersect pamimba tendinous constriction, imbaenda kupatukana kwake mu chapamwamba ndi m'munsi gawo.

Komanso ofunika ponena kuti minofu ndi kuoneka bwino pansi pa khungu, ngati m'chiuno unakhota kapena kutenga, ndipo pamene kuwongola mwendo m'munsi. Komanso, ndi bwino palpated mu ntchafu m'dera chapamwamba.

Udindo wa sartorius ndi

Musculus sartorius nawo m'chiuno flexion ndi atigwira, ndi minofu ili ndi udindo ndi kayendedwe ka outwards, osati inwards. Pamene kasinthasintha mkati a m'chiuno si mbali. Pamene akuyesera kuchita kasinthasintha kunja ndi adamulowetsa kapena ayi konse, kapena zikugwira ntchito pamlingo chosakwanira. Mu atakhala pamalo sartorius kunja kasinthasintha akutsatiridwa ndi zinthu zolimbitsa. Pamene bondo ndi flexed minofu CHIKWANGWANI ali chinkhoswe kumufotokozera, ngati pa nthawi yomweyo akuthamanga m'chiuno flexion.

Tikumbukenso kuti EMG Kupenda anaulula kuti sartorius umagwira ntchito masewero a volebo kapena mpira. Choncho musculus sartorius kumanzere ndi chinkhoswe kumufotokozera m'magulu onse dzanja lamanja (mwachitsanzo, pa masewera a tenesi), ndiponso ntchito kuyenda, kulumpha kapena atakwera njinga.

Choncho, pamodzi ndi ulusi zina minofu sartorius minofu, kugwira ntchito mwa monga m'munsi nthambi kayendedwe, ntchafu amapereka akutembenukira outwards, ndipo ndi udindo kupinda mwendo.

Innervation sartorius

Pakuti innervation musculus sartorius udindo mitsempha femoral, chomwe 2-4 rootlets. Nthambi za mitsempha izi innervate khungu la pa ntchafu mkati ndi medial m'dera la mwendo m'munsi m'mphepete phazi.

Pamene kusintha pathological ya mitsempha femoral angathe paresis kapena ziwalo, komanso amachepetsa kamvekedwe ndi tendon bongo. Yaitali minofu ziwalo kumabweretsa manja ndi maonekedwe a contractures, amene anatsagana ndi nthenda nthambi Kusinthaku mwa kutsegula kwa wathanzi minofu muzikangana.

Komanso, pangakhale chisokonezo kwenikweni mu mawonekedwe a paresthesias, gipostezii kapena mankhwala ochititsa dzanzi zonse. Nthawi zina, m'malo mwake, analemba kusintha tilinazo mtundu hyperpathia pamene odwala ndi ululu woyaka khalidwe omwe sangathe kuchotsedwa analgesics.

Ngati kuphwanya innervation sartorius zambiri wosweka kuyenda, kuti akhoza zimachitika kuchulukitsa kwa m'munsi nthambi flexion a m'chiuno kapena kulephera bwino kukweza m'chiuno.

Kodi angachite ngati kuwonongeka sartorius?

Neuropathy femoral ubongo, zomwe akuphwanya contractility wa sartorius nthawi zambiri ambiri akufotokozera pambuyo opaleshoni m'dera m'chiuno kapena ntchafu. chifukwa angakhalenso sprain kapena psinjika mwachindunji ulusi minofu. Ndi ponena kuti neuropathy angayambe ndi shuga wokwanira.

Ngati zizindikiro za kuwonongeka kwa femoral matenda mitsempha limodzi ndi flexion ya nthambi m'munsi, ayenera amanena kuti katswiriyu ndi. Iye azichititsa kudzifufuza ubongo, electrotherapy, ngati n'koyenera, mankhwala ndi CT jambulani, ndi Kujambula wa danga retroperitoneal ndi chithandizo choyenera.

Pamene kuonongeka sartorius ntchafu ndi ogwira mankhwala kuchipatala. Komanso ntchito njira yosangalala ndi kutambasula wathuyo minofu ulusi, femoral mitsempha anatseka misewu ndi kuwukonza mwendo kwambiri extension m'munsi kusintha nthambi kutalika chifukwa cha chitukuko cha contractures. Dziwani kuti kupeza zabwino ndi zotheka ndi malangizo minofu, amene zimagwirira ntchito zogwirizana ndi zone chiwonongeko.
