Muzongoza, uye avo mabasa

nomuzongoza munhu chinhu chaizvo kunzwisisa mashandiro, nokuda zvakarurama kushanda izvo kunoenderana nokushanda kwenhengo zvomukati zvose.

The nomuzongoza zvinosanganisira vertebrae 32-33: (. 3-4 hrs) mutsipa (. 7 hrs), Chipfuva (. 12 hrs), lumbar (. 5 hrs), Sacral (. 5 hrs) Uye coccygeal. Dziri pakati vertebrae intervertebral discs (23 hrs.). Vertebrae dzinoumba dzakasiyana dzenyika nomuzongoza.

The vertebrae vari vakabatana mumwe shwashwa-tsandanyama midziyo, intervertebral discs, majoini. izvi zvose anotibvumira abate nomuzongoza ari akarurama chinzvimbo uye kukutsigira pamwe zvakafanira kuchinja pakuendeswa. Tinoberekwa kwakavharwa nenyama ehupfumi ari intervertebral discs iri yekudyidzana kunyevenutsa zvakohwewa nezvakanga jerks kana achifamba, vachisvetuka uye kumhanya, izvo chakasvitswa uropi uye musana.

muzongoza

The nomuzongoza rinoumbwa ari remuromo, thoracal, lumbar, sacrum uye coccyx.

Remuromo nomuzongoza zvinoreva rokumusoro mapoka ari musana mbiru. Zvinonzi kusiyaniswa imwe mufambo chaiyo anosika rusununguko uye dzakasiyana-siyana nomusoro masangano. Rokumusoro remuromo vertebrae, akadana atirasi uye Sekaiichi, tinoberekwa ari anatomical mamiriro, izvo zvakasiyana navamwe nemamiriro vertebrae. Atlas uye Sekaiichi anokonzera kurereka uye tenderera musoro wacho.

Thorax ndiye muchipfuva atiitirewo. zvinokosha zvomukati, nokuda kwechikonzero ichi chiri vakaneta. To vanonzi vakakoshesa micheto (12 nomwe).

The lumbar nomuzongoza ine vertebrae zvakakwana hombe, nekuti vari pasi kumukuru mutoro. Vamwe vanhu vane matanhatu lumbar vertebrae. Kwakadaro kutanga muna mushonga unonzi lyumbalizatsiey. 8-10 vertebrae zvikure pamwe chete kuumba sacral nomuzongoza.

The vertebra ane muviri, ane chinhu chakakombama, makumbo maviri, Bearded, vaviri transverse uye articular mana pezvakaitwa. The musana Canal achiumbwa pakati mawindo ari vertebral chematenga, vertebral muviri uye makumbo.

Between maviri pedyo vertebrae ane intervertebral Disc, ndoupi annulus fibrosus uye neerekitironi pulposus. It anoita mashandiro depreciation, yaanobhadhara kuti pedyo vertebrae, kuona mufambo yavo. Musimboti iri akanyudzwa rin'i fibrous, ukaramba chinoumba pakati uye kunodzivisa kuti zvishoma nezvishoma mumatope enyika vertebrae.

The annulus fibrosus rine muzvizhinji ine akaturikidzana uye fibers izvo vakayambukira mu ndege matatu. Kana osteochondrosis anulus fibers vari kutsiviwa vanga rinenge dzimwe nguva zvinogona kukonzera kuparara pakati fibrous mhete uye paumbwe Disc herniation.

nhengo dzose musana takashongedzerwa pamwe ligamentous midziyo. Vertebral chidimbu - maviri vertebral dhisiki nemarunda.

kuti musana iri muna musana canal, uyewo midzi paiya inonzi "bhiza kuti muswe". Musana kunotanga chepfungwa munzvimbo uye kunosvika kune wekutanga uye chechipiri lumbar vertebrae.

Musana, mimicking nemativi ose nomuzongoza, akapoteredzwa mukukutu, nyoro uye arachnoid uye wakaiswa pakati musana canal, uye faibha midzi.

Mapazi kubva musana etsinga midzi (31 nomwe) kuti anobuda intervertebral (foraminarnyh) musana mugero orifices.

Man, kufanana nemamwe vertebrates, ane segmental innervation muviri, kureva, mumwe nomumwe mapazi eumambo musana anokonzera imwe nhengo.

Somuenzaniso, mutsipa uye maoko innervate zvikamu zvacho chokuita remuromo nomuzongoza, chipfuva uye dumbu - a thoracal, sacral chidimbu innervates tsoka, perineum, kuti mugaranhoko uye dundira.

Munguva musana pane thickening pamusoro remuromo uye lumbar. Herniated discs ari remuromo nomuzongoza ndiyo ngozi kupfuura ari lumbar.

Panzira iyo nzvimbo vakachengeta motility uye aikanganiswa zvinetso, chiremba anogona nguva dzose zvokufungidzira apo zvaparadzwa kwakaitika, uye mativi nomuzongoza sei chii.
