Isakhiwo yomgogodla

Abantu abaningi bakuthathe kalula ukubaluleka skeleton, ikakhulukazi yomgogodla. Nokho, ukwenza kanjalo ngeke kukusize ngalutho-ke, ngoba ifeza indima ebaluleke kakhulu ekuphileni kwebantfu. Ukuthi weseka umuntu usesimweni uqotho, ngaphezu, siwulimi usekelo kwezicubu imisipha futhi izitho, wakha udonga izimbotshana thoracic futhi besisu. isakhiwo emgogodleni kuyivumela ukumelana imithwalo enzima, ngenkathi azigcina ivumelana nezimo futhi ukuhamba. Ngokuvamile, lapho uqala kuzindla idivayisi noma ukuthi umzimba, ikakhulukazi yomgogodla, isikhathi ngasinye ehlaselwa ukuhlakanipha nemvelo.

Emgogodleni isikimu iyonke, elula futhi ohlakaniphile ngendlela yalo. Siqukethe 32 amathambo, futhi isakhiwo kanye injongo ihlukaniswe yaba 4 izigaba: sacral, lumbar, thoracic kanye wesibeletho. Esinye sezici isakhi ezahlukene izingxenye yomgogodla wukuthi umnyango ngamunye has eguqa yayo phambili noma emuva. eguqa isiqondiso kushintshana ngababili: yomgogodla wesibeletho uzimisele phambili Curves zokuphumula ezinjalo zibizwa ngokuthi lordosis, thoracic - edlule, ejikeni enjalo ibizwa ngokuthi kyphosis, nokunye. isakhiwo olunjalo olwenza yomgogodla ukumelana imithwalo enzima, ngoba kuyafana isiphethu, okuyinto uba ukushaqeka mfutho, cushioning umthwalo ngesikhathi ehamba futhi egijima.

vertebra ngamunye, ngaphandle wesibeletho lokuqala, kodwa okwengeziwe ukuthi kamuva, siqukethe umzimba kanye arc. I arc ichaza i ukuvulwa ngendlela vertebra. Yomibili le izimbobo ichaze umgodi phakathi ikholomu vertebral lapho, ngaphansi ezisindayo unogada ithambo emgogodleni. Ngaphezu kwalokho, vertebra ngamunye has a kabili ezimbalwa futhi kabili. Bona, kanye akwazi ukugcina intervertebral nemisipha, unikeze bamba phakathi amathambo.

Manje ake sixoxe umnyango ngayinye. Kufanele uqale Yiqiniso, nge entanyeni. Luhlanganisa zonke 7 amathambo. Ubukhulu of amathambo wesibeletho lincane kakhulu kunabo bonke abanye. Ngokuvamile, usayizi amathambo kwandisa kakhudlwana coccyx. Lokhu kuyadingeka ukuze sivale lapho sisilela umthwalo okwandisa.

Kodwa emuva amathambo wesibeletho. Mangisho ukuthi isakhiwo sabo onhlobonhlobo. Iningi kakhulu kuyehluka kuneminye vertebra lokuqala, ubizwa ngokuthi Atlas. Akazange abe nomzimba, yakhiwa lwesikhathi nezinqubo. Eyesibili umzimba, kodwa futhi ihluke kwezinye amathambo wesibeletho ngenqubo ezinkulu, ukubizwa ngokuthi izinyo. Le nqubo eksisi emhlabeni lapho ikhanda ukuphotha. Ezinhlangothini amathambo wesibeletho kungabonwa vestigial ameva fin. Ngaphezu kwakho konke basuke obonakaliswe 6 vertebra. Kuvele ukuvulwa kwakhiwa ngesikhathi arc we amathambo wesibeletho has simise esingunxantathu.

amathambo thoracic umnyango ube usayizi umzimba okukhulu, ukuma izimbobo ishintshelwa isekhula ku inqubo transverse of amathambo thoracic uMnyango izimbobo ubambo.

Siyaqhubeka ukubheka isakhiwo sokukhubazeka komgogodla. Front Landelayo - lumbar. Kwakukhona nesinye ukwanda ubukhulu umzimba amathambo. Ngaphezu kwalokho, i-lumbar amathambo kuhluke owahlanganyela elungiselelweni ovundlile izinqubo zayo. usayizi Hole zincane.

sacral vertebrae umnyango ahlukaniswe kuze iminyaka yobudala 25 kuphela, ngesikhathi zikhula ndawonye. Ithambo okuholela ubizwa ngokuthi sacrum futhi has simise esingunxantathu. Kuyingxenye ukhalo.

emgogodleni Lumbosacral lihlukile lonke usayizi omkhulu we amathambo. Phela, lezi akhawunti inxenye enkulukazi umthwalo.

Uma ucabangela isakhiwo yomgogodla, nje abakwazi sikhohlwe akwazi ukugcina intervertebral. Zenza imisebenzi eminingana: yokuxhuma amathambo komunye nomunye bese ukunikeza ukuhamba sokukhubazeka komgogodla. yizinhlobonhlobo okunjalo kufezwa ngokusebenzisa isakhiwo esiyingqayizivele. I disk inezingxenye ezimbili: core, okuyinto Kusekelwe uqwanga okuqinile futhi obukhulu indandatho zezinzwa ihlule. Uqwanga eqala umthwalo oluyisisekelo, indandatho kwalo ivala ke.

Nakubukwa jikelele, isakhiwo emgogodleni kufanele kakade kucace. Yiqiniso, kunezinto eziningi kakhulu imininingwane amancane izici, kodwa isihloko ukudalula yonke imininingwane nje akwanele.
