Anatomy o te pekehoe waha, te hanga me te mahi

hanga tuaiwi tangata te ake o neke atu i te 30 pekehoe, e kua ngā ki 5 wehenga. Tenei waha, rei, lumbar, sacrum me te iwi timu. Ia o te tuaiwi he tona mahi, me te hanganga āhuatanga. He he he wehenga i waenganui i te pekehoe, i runga i te teka, me te pono. Ka taea te pēnei Sacrum me iwi timu ki te rōpū o te pekehoe teka.

tuaiwi waha

Kia pehea te nui o te pekehoe waha he rerekē i te toenga? Me pēhea e titiro ratou? Ka taea te ngāwari whakahoki ēnei pātai, e matau i te hanganga o te tuaiwi.

I roto i te tuarā, 7 pekehoe waha, e te hunga pono i roto i te rōpū. E honoa ana ratou ki tetahi ki tetahi taputapu nape-uaua motuhake, e ngā te kōpae intervertebral me hononga. hanganga hangore taea ki a koe peia ka peia ki faaiti i te kawenga ki runga ki te tuaiwi, me te whakarite i tona haumaru.

te pekehoe katoa o te tuaiwi waha ki tau, te whakawhanake me te hanga i te lordosis - he tauhia motuhake tītaha haamana'oraa o te kōpapa. He rerekē i ia atu ia pūwaha.

Ko te tinana o te pūwaha waha, te tuatahi, me te tuarua, tino rerekē i ētahi atu katoa. Nā ki te pekehoe 1 me te 2, ka taea e te tangata tahuri tona matenga ki te taha, me te tītaha ki te hanga i te upoko.

tinana o te pūwaha

Ko te hanganga o te pekehoe ki te katoa ōrite. E te tinana me te tukanga pewa ia pūwaha. Body - tenei wahi pūwaha thickened te tihi me te raro e anga ki te atu pekehoe, mua, me te taha mata hakoko he iti, i roto i te hoki papatahi.

rawa katoa o te tinana vertebral te ki te poka faaamuraa i roto i nei oko toto me mutunga karere.

Ko te pewa o te pūwaha hanga te puta iti vertebral whāiti te hoki me taha. Kei runga ake ia atu, arcs hanga te awa filosilivá. Hoki ia e tika te ua.

mata Posterolateral tinana vertebral kamata whāiti i hanga waewae kikorangi vertebral e haere ki te kikorangi vertebral pereti.

I runga i nga papa (o runga me raro) waewae i tapahia vertebral tēnā. Piri ki te pūwaha pātata, i whai ahua ai ratou rua intervertebral.

E 7 ngā tukanga pūwaha pewa. whakahaua tukanga Spinous te posteriorly. Ko te toe 6 takirua. Te tahi o runga, tahi o raro me te tukanga hake.

4 katoa e rite rawa ki te papa tahi tukanga articular. Ki te to ratou awhina, kua honoa te pekehoe pātata.

Anatomy o te pekehoe waha

pekehoe waha i roto i te rongoā i huaina pūāhua ārepa (reta C me te tau i te 1 ki te 7). E huru no te pekehoe e tinana iti atu whakararo. mata hakoko o te tinana (tika runga, mua o raro ki te hoki). I 3-6 pekehoe i runga i te mata o runga kite tapa taha teitei e hanga i te matau tinana.

poka whai tuaiwi rerekē āhua tapatoru, te whanui.

tukanga Articular whakaritea ki ētahi atu, poto, obliquely tu, me o ratou mata ranei paku ohu nei flat ranei.

tukanga Spinous tīmata ki te 2, 7 whakamutunga pekehoe e āta roa. I wahia e 6 pūwaha te i te mutunga, he raro paku hehema.

He poto, whakahaua ki te taha te tukanga hake. I te tihi o ia hiwi toro parautanga. tuwhaina e te reira i te fepulopulasi i runga i te mua, a muri, rite haere te reira i te io tuaiwi.

he ngā hoki ona rerekētanga Anatomy o te pūwaha waha. Hei tauira, 6 pūwaha rawa whakawhanakehia taupa mua. Katia ki reira i reira haere kakī iatuku, e aki nei i roto i te mate toto ki a ia. Na reira, i huaina te tukinga ko tunewha.

Ko te tukanga hake e hanga e e tukanga rua. Mua - he rudiment o nga rara, hoki - i te reira koe tukanga. tukanga rua - te whakatuwhera i te reira tūnga. Hole-ka karanga toto vertebral, rite tika ai i roto i te iatuku vertebral ko Vienna me te pukuaroha plexus io.

Rerekē i te toenga o te pekehoe

rerekē i te toe pekehoe: te pūwaha tuatahi waha (mahere) me te tuarua (tuaka pūwaha), te whitu (kohuki pūwaha).

Ko te pūaha tuatahi

I roto i te pukapuka mahere whenua e kore tinana me te tukanga spinous. kanohi pūwaha rite te mowhiti i hanga e rua arcs (mua, a muri). e toaati e papatipu lateral motuhake ēnei arcs. Kei te hono Top kōpapatanga porotītaha ki te wheua kōpako, ko te raro ki te mata tata papatahi o te rua te pūwaha.

I te mua o te pewa he tukinga, i te hoki i reira ko te wāhi iti o te popoki - niho poka.

I te tuarongo o te pewa, ko te tubercle, a ki runga ki te tihi o te awa parautanga reira iatuku vertebral (tahuri ētahi wā ki te hongere).

He ahurei i roto i ētahi atu Anatomy o te pukapuka mahere pekehoe waha. Fakataha ki te puka pekehoe rua te huinga ahurei e taea ki te mahi i ngā nekehanga o te matenga.

pūwaha tuarua

kua he upwardly whakahaua te pūwaha tuarua i te tinana niho, te matamata o e pito (tuhia ki te mahere niho fossa Anterior mata articular, te hake mahere nape tahi pātata ki te mata muri).

huri te reira i te angaanga niho me te kakī waha tuatahi huri noa.

tukanga hake waho nga fepulopulasi me awaawa o te karere tuaiwi.

whitu o pūwaha

Ko rerekē i roto i taua kua reira he tukanga spinous roa (nerazdvoenny) Tukuoro pūwaha waha tuawhitu. Kei te kite ia ki te kanohi tahanga, a te mea ohie ki te ite i roto i roto i te kiri. No te mea o tenei āhuatanga, ka ka tona ingoa. Haunga tenei, tetahi pūwaha me ngā tukanga roa hake. Ko te rua rite ranei iti, ranei ngaro.

maha kua he tuhaa (fossa costal) te mata o raro o te mata taha o te tinana. Tenei ara huinga pera-ka karanga ki te upoko 1 rara.

te pekehoe waha katoa - he wheua kaha, me te kaha. E matau ratou āhuatanga, e taea te whakaritea ngāwari tuaiwi wheua ahua.
