Nemamiriro evanhu marangwanda: ilium

Iliac nharaunda anomiririra mumwe kati uye rusvingo veshure ane resamende chimiro. yokumusoro Muganhu Its ndiye ilium (PC), zvikurukuru penyika yacho, muganhu Anterior - kutanga mapfupa nemarunda, zvemukati - kubatana kuti sacrum, rezasi muganhu mutsetse uri kusazivikanwa. PC panguva mabasa sezvo marangwanda ari nharaunda, iyo wanamatira shure abdominal rusvingo netsandanyama. Pamwe chete, tsandanyama uye mapfupa vanoumba batana butiro.

Saka, kuti sacrum mativi ose vakakoshesa makuru mapfupa iliac, vane woita pamusoro, saka hakutombonzwiki zvakanaka mumuviri womunhu.

The ilium ndiro rakakura kupfuura mamwe ose mapfupa vanoumba marangwanda ose pelvic dzevanhu dhipatimendi. repasi chikamu chacho zvishoma thickened uye anonzi PC muviri, izvo anoumba yokumusoro chikamu acetabulum. With muviri ilium uye sacrum vari chokuita pechidya pfupa. Munguva yokuyaruka PC merges pamwe pubic uye ischial mapfupa munzvimbo yacho acetabulum, nokudaro achiumba pelvic pfupa.

On yomukati divi muviri chinopinda mutsetse ive chinhu chakakombama chimiro, uye riri kumusoro widest chikamu mapfupa, rinonzi PC bapiro iri, rezasi mugove izvo tapered, uye okumusoro - wakashamira. Thickened pamucheto bapiro, kuda kwake abdominal tsandanyama, izvo mavanga anodhindwa pamusoro pfupa riri muchimiro mitsara mitatu (miromo) wokunze, womukati uye zvenguva. Zvinofanira kucherechedzwa kuti rokumusoro chikamu wamapapiro vanonzi iliac penyika. Mizinga ine S-chimiro uye inoguma pamberi pamberi pamusoro PC, chinogona kubatwa pamusoro womunhu muviri kubudikidza ganda, shure chete - musana repamusoro iliac mafupa.

Cherechedza kuti aitungamirira pamucheto ilium spliced kuti pfupa kubva pubic, uye rwemberi kumucheto muganhu sciatic notch. Chokunze Chikamu bapiro ndiyo pfungwa kuda nokuda gluteal tsandanyama, uye pamusoro menzvimbo bapiro, anonzi iliac fossa, riri auriculate articular pemvura inova nzvimbo rinobatanidza sacral pamusoro. Above ndiro iliac tuberosity, iyo inoshanda nokuti kugadzira ari shwashwa.

Iliac fossa ndiyo nzvimbo kuda yacho iliac tsandanyama. Zviri yakabatana lumbar tsandanyama uye zvinobva kumusoro fossa, yomukati miromo penyika uye Anterior sacral uye lumbar shwashwa. Pamwe chete yakakwirira psoas iliac tsandanyama paChikoro paumbwe abdominal tsandanyama rusvingo (kumashure). Uyewo kune mabasa ayo anosanganisira hudyu flexion.

Saka, yokumusoro chikamu PC vakagumisa mberi uye neshure chimiro miganhu maviri uye chokunze chikamu anoverengeka chakakwirira. Kazhinji, zvakazorodza pfupa kunobva tsandanyama kuda pfungwa ayo inoumbwa zvakasiyana mitsetse, anooneka zvikuru nemichinjiziri, Makomba nomuzongoza.

Nokudaro, iliac pfupa rimwe zvakamisa hurongwa matatu, izvo zvinoumba imwe pelvic pfupa. Muvanhu, hwakabatana kune sacral pfupa (Fusion mashanu vertebrae) uye acetabulum nzvimbo merges nezvimwe maviri zvinoumba pakati chiuno. Munharaunda iyi, tsandanyama vari zvakabatanidzwa, zvikurukuru, iliopsoas, izvo nokuda kwayo marwadzo kunokonzera pabazi kuenda mberi, kuti, kudzora kufamba kwavo uye nechokumusoro kuti chiuno flexes pamagaro uye lumbar nomuzongoza.

Achiratidza, zvinofanira kucherechedzwa kamwe zvakare kuti ilium Vane basa iri kubhururuka tsandanyama, uchuvstvuet pakugadzirwa uye kudzora rezasi richiripo sangano. Akabatanidzwa chinjwa mapfundo tsandanyama, kuti PC uyewo inopa dziviriro nokuda zvinyoronyoro nhengo dzomuviri, apo kuunza naye inofamba wakatsetseka. Uyezve, sezvo chikamu kwevanhu marangwanda, ilium ndiye puranga, iro rinoreva mumwe chikamu chomuviri, kureva maoko nemakumbo rezasi.
