Ubume ngamathambo omntu: ilium

ummandla Iliac umele omnye kwezahlulo isisu kunye nodonga bakhulise ngokumila kumkhombe. umda ayo aphezulu nguye ilium (PC), ingakumbi Crest layo, lo umda sobuKristu - ekuqaleni kwamathambo kunye nemisipha, zangaphakathi - uqhagamshelwano ukuya sacrum, umda kumgca ongezantsi angaziwa. PC ngaxeshanye isebenza amathambo mmandla, encamathele ngasemva izihlunu eludongeni esiswini. Ndawonye, izihlunu namathambo zenza iqweqwe ashinyeneyo.

Ngoko ke, ukuba sacrum omabini la maqela amathambo ezinkulu iliac eqhotyoshelweyo, nto leyo ibe ngaphezulu ajikelezayo, ukuba waziva njalo kakuhle emzimbeni womntu.

Le ilium yeyona inkulu onke amathambo eyenza amathambo kwisebe kwabantu zangasese. inxalenye yawo asezantsi noko anquma kwaye sibizwa umzimba PC, owenza nakumphezulu acetabulum. Ngenxa umzimba ilium kunye sacrum oxhulumene kwi ithambo ethangeni. Ngexesha lokufikisa PC zidibana kunye namathambo zikawonke wonke kunye ischial kwingingqi leyo acetabulum, kanjalo zakha ithambo zangasese.

Kwicala engaphakathi umzimba ipasisa umgca ibe imilo arc, kwaye ibekwe ngaphezu ebanzi iinkuni, ekuthiwa iphiko PC, inxalenye esezantsi yayo tapered, kwaye eliphezulu - iphangalele. edge anquma ngenxa iphiko, eqhotyoshelwe izihlunu zakhe esiswini, apho amanqaku ziprintwe wethambo ngohlobo imigca emithathu (imilebe) engaphandle, ngaphakathi kunye neziphakathi. Kufuneka kuqatshelwe ukuba inxalenye engentla kwamaphiko zibizwa ngokuba Crest iliac. Kama sine-S-imilo kunye iphela phambi PC ngaphambili top, enokuphathwa emzimbeni lwabasebenzi eluswini, emva efanayo - umva iliac eliphezulu ithambo.

Qaphela ukuba ngohlangothi aziintloko ilium spliced ukuya ithambo le zikawonke wonke, yaye udini elingasemva umda kweyona notshi sciatic. Inxalenye engaphandle ye-SCA ingongoma sothimbo lokuba izihlunu gluteal, yaye inxalenye engaphakathi iphiko, ochazwa ngokuba fossa iliac, ibekwe umphezulu articular auriculate leyo linxiwa uqhagamshelwano ukuya kumphezulu sacral. Ngaphezu lelona tuberosity iliac, nelisebenza ukuba ilungisa lungu.

Iliac fossa linxiwa kuthinjwe esihlunwini iliac. Kuyinto ezikufutshane izihlunu empontshwa kwaye evela phezulu fossa, imilebe yangaphakathi Crest, kunye akudala sacral kunye empontshwa lungu. Kunye nezihlunu high iliac psoas ngenela ekubunjweni udonga izihlunu esiswini (umva). Kwakhona nemisebenzi yayo iquka hip flexion.

Ngoko ke, inxalenye eliphezulu PC rounded ngaphambili kunye nefomu abasemva lunamaqoqo yomibini engaphandle ephakamileyo eziliqela. Ngokubanzi, isiqabu wethambo kuxhomekeke ngeengongoma izihlunu attachment leyo akhiwa imigca ezahlukeneyo, nasentshonalanga, pits umqolo.

Ngaloo ndlela, ithambo iliac yenye leekhomponenti ezintathu, nto leyo yenze ithambo enye zangasese. Xa abantu, elidityaniswe kuyo ithambo sacral (ngxubevange omqolo ezintlanu) kunye nendawo acetabulum zidibana kunye nezinye iinxalenye ezimbini isinqe. Kule ndawo, izihlunu kuqhotyoshelwe, ingakumbi, iliopsoas, leyo ngenxa ucutheko yayo kubangela kwesebe ukuya phambili, oko kukuthi, ukulawula intshukumo yabo omeleza isinqe flexes inyonga umqolo empontshwa.

UPawulos, kufuneka kuqatshelwe kwakhona ukuba ilium umsebenzi kabani na ukuba entabeni imisipha, uchuvstvuet ukwakheka nolawulo Imilenze asezantsi. Onamathele amalungu ezinokususwa kunye nezihlunu, i-PC kwakhona ibonelela ukhuseleko iinxalenye ezithambileyo omzimba, lo gama kuqinisekiswa ukuba isiphakamiso egudileyo. Ukongeza, njengenxalenye ngamathambo omntu, ilium na isakhelo, eli liyithweleyo elinye ilungu lomzimba, ezizezi nemilenze.
