Kapangidwe ka mafupa anthu: ilium

Iliac dera Bwaloli ndi limodzi mwa magawo cha mimba ndipo khoma kumbuyo ali ndi ufa mawonekedwe. malire ake chapamwamba ndi ilium (PC), makamaka Crest zake, zapambuyo malire - chiyambi cha mafupa ndi Mitsemphayi, mkati - kugwirizana kwa sacrum, m'munsi malire mzere ndi anonymous. PC nthawi yomweyo amachita ngati mafupa a dera, amene anaphatikiza kumbuyo kwa minofu m'mimba khoma. Pamodzi, minofu ndi mafupa kupanga chivundikiro wandiweyani.

N'chifukwa chake sacrum ndi mbali zonse Ufumuyo kwambiri iliac mafupa omwe anamaliza pamwamba, kotero kuti anamva bwino pa thupi la munthu.

The ilium ndi yaikulu mafupa onse amene amapanga mafupa a dipatimenti anthu m'chiuno. mbali m'munsi penapake unakhuthala ndipo akutchedwa PC thupi, imene imagwiritsidwa kumtunda acetabulum lapansi. Ndi thupi la ilium ndi sacrum olumikiza fupa ntchafu. Pa PC msinkhu merges ndi mafupa obisika ndipo ischial m'dera la acetabulum ndi, motero kupanga fupa m'chiuno.

Kumbali lamkati la thupi akapitirira mzere mu mawonekedwe ndi Arc, ndi ili pamwamba mbali linafalitsidwa kwambiri mafupa, wotchedwa PC mapiko, m'munsi gawo limene tapered, ndi chapamwamba - wakulitsidwa. Unakhuthala m'mphepete mwa mapiko a, zaikidwa thupi lake m'mimba, omwe zizindikiro amasindikizidwa pa fupa mu mawonekedwe a mizere itatu (milomo) lakunja, mkati ndi wapakatikati. Tikumbukenso kuti kumtunda kwa mapiko akuitanidwira iliac Crest. Comb ali S-mawonekedwe ndipo itha kutsogolo kutsogolo pamwamba PC, sipangakhalenso anamva pa thupi kudzera pakhungu, kumbuyo chimodzimodzi - kumbuyo chapamwamba iliac fupa.

Onani kuti m'mphepete atongi wa ilium ndi spliced kuti fupa la obisika a, ndi m'mphepete kumbuyo kwa malire a mphako sciatic. The gawo lakunja la mapiko ndi mfundo za ubwenzi kwa minofu gluteal, ndi pa gawo lamkati la mapiko a, amatchedwa iliac fossa, ili articular pamwamba auriculate amene ali malo kugwirizana kwa padziko sacral. Pamwamba ndi iliac tuberosity, amene akutumikira pa kukonza mitsempha.

Iliac fossa ndi malo za ubwenzi wa minofu iliac. Ndi pafupi ndi minofu lumbar ndi zimachokera pamwamba fossa ndi milomo mkati Crest ndi zapambuyo sacral ndi lumbar mitsempha. Pamodzi ndi mkulu minofu psoas iliac nawo mu mapangidwe m'mimba minofu khoma (kumbuyo). Komanso Zinchito zake zikuphatikiza m'chiuno flexion.

Choncho, gawo chapamwamba PC anamaliza kutsogolo ndi mawonekedwe kumbuyo kwa protrusions awiri ndi gawo lakunja la angapo okwera. Nthawi zambiri, thandizo la fupa zimadalira mfundo minofu kuphatikana amene anapanga ndi mizere osiyana, zitunda, maenje ndi msana.

Motero, iliac fupa ndi chimodzi mwa zigawo zitatu, zomwe ndi limodzi m'chiuno fupa. Mu anthu, chikugwirizana ndi fupa sacral (maphatikizidwe wa vertebrae zisanu) ndi malo acetabulum merges ndi zigawo zina ziwiri za mafupa a chiuno ndi. M'dera lino, minofu amagwira, makamaka iliopsoas, omwe chifukwa chidule chake amachititsa nthambi kupita chitsogolo, ndiye kuchepetsa kayendedwe kawo ndi limakhazikitsa mafupa a chiuno flexes m'chiuno ndipo lumbar msana.

Polongosola mwachidule, tisaiwale kamodzinso ilium ndi ntchito amene ali ku phiri minofu, uchuvstvuet mu mapangidwe ndi ulamuliro wa m'munsi kayendedwe nthambi. Nadzaphatikizana ndi zimfundo makina ndi minofu ya PC amatipatsanso kungakutetezeni mbali zofewa a thupi, pamene kuonetsetsa iye zoyenda yosalala. Komanso, monga gawo la mafupa anthu, ilium ndi chimango, amene amanyamula zina mbali ya thupi, womwe ndi miyendo m'munsi.
