Ukwakhiwa kwesifuba somuntu: ithambo le-iliac

Isifunda se-aliac sinye yezingxenye zodonga lwangasemva kwesisu kanti linomumo ongenawo. Umngcele wayo ongenhla uyithambo le-alkali (I-PC), ikakhulukazi umgogodla wayo, umngcele ongaphambili - ukuqala kwethambo ne-ligament, ukuxhumana kwangaphakathi ne-sacrum, umngcele ophansi umelela umgwaqo ongenamagama. I-PC ngesikhathi esisodwa isebenza njengamahlumela alo mkhakha, lapho izixuku zodonga lwangasemva komzimba zifakwe khona. Kanye, imisipha namathambo zakha icala elibi kakhulu.

Ngakho-ke, amathambo amakhulu ama-alacac ahlanganiswa ne-sacrum ezinhlangothini zombili, ezinama-round apriced, ngakho-ke ahloswe kahle emzimbeni womuntu.

I-ileum iyona enkulu kunawo wonke kuwo wonke amathambo awenza isigaba se-pelvic skeleton yabantu. Ingxenye yayo engezansi iyancipha futhi ibizwa ngokuthi umzimba we-PC, owenza ingxenye engaphezulu ye-acetabulum. Amathambo ama-Sacral kanye nama-femal axhunyiwe nomzimba we-ankac bone. Ngesikhathi sokukhulelwa, i-PC ifaka amathambo ashicikayo kanye ne-ischium esifundeni se- acetabulum, ngaleyo ndlela yakha ithambo le-pelvic.

Ohlangothini lwangaphakathi lomzimba luwumzila ngendlela ye-arc, futhi ngenhla ingxenyana enkulu yethambo, ebizwa ngokuthi iphiko le-PC, ingxenye engezansi eyancipha, futhi ingxenye engaphezulu iyanwetshwa. Umkhawulo wephiko uqina, imisipha yamathumbu ifakwe kuwo, imidwebo yayo ebhalwe emathanjeni ngendlela yemigqa emithathu (izindebe): yangaphandle, yangaphakathi kanye ephakathi. Kumele kuqashelwe ukuthi izingxenye ezingenhla zamaphiko zibizwa ngegama Ama-crests amathambo ama-iliac. Ikhefu liyi-S futhi liqeda phambili kwePC engenhla, elingasetshenziswa emzimbeni womuntu ngesikhumba, ngemuva - ngethambo eliphakeme eliphakeme le-eleal.

Qaphela ukuthi umkhawulo wangaphakathi we-ilium bone ufaka ithambo le- pubic, kanye nemingcele ye-posterior emkhawulweni we-sciatic. Ingxenye yangaphandle yephiko yindawo yokunamathiswa kwemisipha ye-gluteal, futhi engxenyeni yangaphakathi yephiko, ebizwa ngokuthi i-iliac fossa, kune-surface articular eyakhelwe indlebe, okuyindawo yokuxhuma ebusweni be-sacrum. Ngaphezulu kunesifo sofuba esinama-aliac, esisebenzela ukuqinisa imigudu.

I-fossa ye-Iliac iyisayithi lomsizi we-aliac. Ihlangana ne-lumbar ye-muscle futhi ivela engxenyeni engenhla ye-fovea, i-lip yangaphakathi ne-sacral yangaphakathi ne-lumbar ligaments. Kanye nomsila omkhulu we-lumbar, umsila we-aliac Ubamba iqhaza ekwakheni isisindo somsipha odongeni lwesisu (ngemuva). Futhi, imisebenzi yakhe ihlanganisa ukuhamba kwe-hip.

Ngakho, ingxenye ephezulu ye-PC ihlanganisiwe, ifomu langaphambili nangemuva i-projections emibili, futhi ingxenye engaphandle iphakanyisiwe. Ngokuvamile, ukukhululeka kwethambo kuxhomeke emisipha, kumaphuzu okunamathiselwe okuyiwona imigqa ehlukene, imigwaqo, imigodi kanye ne-awns.

Ngale ndlela, I-bone i-alkali ingenye yezinto ezintathu ezakha isifuba esisodwa se-pelvic. Kubantu, ixhuma emthanjeni we-sacral (i-fusion ye-vertebrae emihlanu) futhi ifakwe nezinye izingxenye ezimbili ze-pelvis esifundeni se-acetabulum. Kule ndawo, imisipha ihlanganiswe, ikakhulukazi esifundeni se-aliac-lumbar, okuyilapho, ngenxa yokuphikisana kwayo, kubangela ukuba isilwane siqhubekele phambili, okungukuthi, silawula ukunyakaza kwayo, futhi siqinise isikhumba, senza i-hip kanye ne-lumbar spine.

Ukufingqa, kufanele kuqashelwe futhi ukuthi ithambo le-aliac , Umsebenzi ozoqinisa imisipha, Izwa ngesikhathi sokubunjwa nokulawula ukunyakaza kwezitho ezingezansi. Ahlanganiswe namajoyina futhi ahambelana nemisipha, i-PC nayo ihlanganisa ukuvikela izingxenye ezithambile zomzimba, kuyilapho ihlinzeka ngokunyakaza okubushelelezi. Ngaphezu kwalokho, njengengxenye yamathambo omuntu, i-ileum isebenza njengenhlaka, lapho ezinye izingxenye zomzimba, okuyizitho ezingezansi, zihlanganisiwe.
