Emgogodleni womuntu, isakhiwo nokusebenza

emgogodleni Human, isakhiwo okuhlangabezana imisebenzi eziyisisekelo zokuphila kuyisisekelo umzimba wonke, ukwesekwa skeleton, Yekhanda, izitho eziningi zangaphakathi, yemisipha futhi yamafutha amaningi emzimbeni. Umthwalo phezu emgogodleni kuyinto inani elikhulu, kodwa esisindo kwasakazwa ngokulinganayo, umthwalo usemahlombe emaphethelweni esifubeni ukhalo. Kanjalo waphawula okunemibandela isisindo ibhalansi.

neminyango Key

The main emgogodleni yomuntu: i-lumbar futhi sacral, thoracic kanye wesibeletho. I engenhla ahlukaniswe, wesibeletho, siqukethe 7 amathambo ukucushwa ezahlukene kanye nosayizi. Ngezansi 12 izingcezu esifubeni, zingabantu inkulu kakhulu kunangendlela entanyeni exhunyiwe yezinyoni ubambo. Le ngxenye ubambo ingena amathambo lumbar amahlanu, lokulandisa umthwalo oyinhloko. Bese kufika sacrum ka amathambo ezinhlanu esingasebenzi.

Isakhiwo yomgogodla yomuntu kunalokho xaka, multi-ngxenye. Anakho ukuma lwalugobile, okuvumela ukuba ube olinganiselayo, kanye kunikeza wonke umzimba cushioning izakhiwo ezidingekayo ukuze ukunyakaza ngokushesha futhi abukhali. emgogodleni womuntu, isakhiwo lapho sicabanga ukuba ngomunye izidumbu multi-olwakhiwe kakhulu. Kuqala ngendlela esikhulisa lokuqala nelesibili vertebra we wesibeletho ikhadi. Eyokuqala, ngokuthi "Atlas" siqukethe ithambo nemengamo futhi okushiwo ngokuqondile base Yekhanda. Ukusilandela "epistrophe" ingxenye kufakwe "Atlas". Nale pair of alingana nekhanda lomuntu kungaba rotated bacondze etindzaweni letehlukene kanye esitshekile.

sengozini

Ezinye izindaba zika-amathambo nsé nomunye yobujamo kuphela kuhluke ngosayizi. Bonke sizungezwe imisipha yesifuba, esiswini, ukhalo futhi emuva.

emgogodleni womuntu, isakhiwo okuyinto kubangelwa ezihlukahlukene izici kuphathelene, kuyingxenye sengozini zomzimba womuntu. Ngisho avikeleka izivikeli mzimba ukuhlasela zonke izinhlobo izifo ezibangelwa amagciwane, ke echayeke imvelo lokukhanda. Ngisho ukukhanya, ngezinye izikhathi wenze ukuhlukumezeka ezincane inflicted kusuka ngaphandle zingaphazamisa ukusebenza yayo. Ingasaphathwa ukuhlukumezeka okukhulu nge ukulimala emalungeni intervertebral, okuyinto nakanjani iphele ukukhubazeka.

emgogodleni

Amathambo zimikiswa nge izinqubo eziningana lapho isidumbu vertebra sihambisane abathandekayo eduze. Ngokuhlanganisa isimiso evumela bathuthe e amplitude ezithile. Kuvele gasket nokunwebeka phakathi vertebrae kukhona akwazi ukugcina cartilage, ithambo evele ukuhlinzeka ngokuhlukana. Ngaphakathi yomgogodla kanye lonke ubude inohlelo ekhethekile imbobo-siteshi emgogodleni - ngesisekelo uhlelo hematopoietic zomzimba. Noma yimuphi shift kungaba cindezela ubuchopho noma kubuqede. emgogodleni Human, isakhiwo okuyinto ngokuphelele ngokuya ukusebenza, kodwa iphephile ekulimaleni. Ngakho-ke, kufanele ugweme ukunyakaza nokulayishwa futhi kuhlasimulise.
