Zingaki Izinsana Ezizalwa Ngazo Futhi Kungani Ziba Nabantu Abangaphezu Kwabantu Abadala?

• Ayini amathambo enziwe, vele?
• Ukushintsha ithambo njengoba izingane zikhula
• Yini iqhaza le-calcium kukho konke lokhu?
• Izinguquko zamathambo aziyeki lapho
• Ake sibe namaqiniso amathambo amnandi
• Amaqiniso amathambo
• Ukuthatha

Kungaba nzima ukukucabanga lapho ubheka umntwana omncane osanda kuzalwa, kepha lelo sana linamathambo azungeze ama-300 - futhi lawo mathambo akhula futhi aguquka ukuma nsuku zonke.

Ngakolunye uhlangothi, abantu abadala banamathambo angama-206, akha amaphesenti angaba ngu-15 esisindo somzimba wabo.

Linda - ngabe sivele sathi izingane zinamathambo acishe abe yikhulu kunabantu abadala? Kungenzeka kanjani lokho?

Yebo, noma amathambo ebonakala eqinile futhi eqinile, empeleni akhiwa izicubu eziphilayo ne-calcium ehlala yakhiwa futhi ilahlwe kuyo yonke impilo yakho.

Ake sibhekisise ukuthi lokhu kukuchaza kanjani ukungafani phakathi kwengane nawe.

Ayini amathambo enziwe, vele?

Amathambo amaningi enziwe ngezingqimba eziningana zezicubu:

• i-periosteum: ulwelwesi olugqinsi olungaphandle kwethambo
• icwecwe bone: ungqimba olubushelelezi, oluqinile olubonakala emathanjeni emathambo
• okukhanselwayo: izicubu ezinjengesiponji ngaphakathi kwethambo elihlangene
• umkantsha: umnyombo ofana nejeli wamathambo owenza amangqamuzana egazi.

Inqubo yokukhula kwamathambo ibizwa ngokuthi yi-ossification. Empeleni kuqala cishe isonto lesishiyagalombili lokukhula kombungu - kuhle kakhulu!

Noma kunjalo, ngesikhathi sokuzalwa, amathambo omntanakho amaningi enziwa ngokuphelele ngoqwanga, uhlobo lwezicubu ezixubile ezilukhuni, kodwa eziguqukayo. Amanye amathambo omntanakho omncane enziwe ngoqwanga ukusiza ukugcina ingane imnandi futhi, futhi, ithambile.

Lokho kuguquguquka kuyadingeka ukuze izingane ezikhulayo zikwazi ukusonga endaweni evalekile yesizalo ngaphambi kokuzalwa. Futhi kwenza kube lula kumama nasenganeni uma sekuyisikhathi sokuthi ingane yenze uhambo olujabulisayo ngomsele wokuzalwa ngesikhathi sokubeletha.

Ukushintsha ithambo njengoba izingane zikhula

Njengoba ingane yakho ikhula ifinyelela ebuntwaneni, iningi lalo uqwanga luzothathelwa indawo ithambo langempela. Kepha kukhona okunye okwenzekayo, okuchaza ukuthi kungani amathambo angama-300 lapho ezalwa eba ngamathambo angama-206 esekhulile.

Amathambo omntanakho amaningi azohlangana ndawonye, ​​okusho ukuthi inani langempela lamathambo lizokwehla. Isikhala esihlukanisa imikhawulo yamathambo amabili agcina exubene naso siyi-cartilage, njengezicubu onazo ekhaleni lakho.

Ukuhlanganiswa kwamathambo kwenzeka emzimbeni wonke. Ungaqaphela ukuthi kunesikhala esisodwa noma eziningi ezithambile phakathi kwamathambo kugebhezi lomntanakho. Lezi "zindawo ezithambile" zingakudida kancane, kepha zijwayelekile ngokuphelele. Babizwa ngama-fontanelles, futhi ekugcineni bazovala njengoba amathambo ekhula ndawonye.

Ukushintsha uqwanga ngamathambo ahlanganisiwe kuqala lapho imithambo yegazi emincane - ebizwa ngokuthi ama-capillaries - iletha igazi elinothe ngomsoco kuma-osteoblast, amaseli akha amathambo. Ama-osteoblast akha ithambo elimboza uqwanga ekuqaleni bese ekugcineni lithatha indawo yalo.

Ngemuva kwalokho, ukukhula kwamathambo ezinganeni kwenzeka ekugcineni kwamathambo amaningi, anezinhlayiya zokukhula. Izicubu ezikhulayo epuletini ngalinye zinquma usayizi wokugcina nokuma kwethambo. Lapho umuntu eyeka ukukhula, amapuleti okukhula ayavalwa.

Amapuleti okukhula abuthakathaka kunezinye izingxenye zamathambo engane yakho, ngakho-ke atholakala kalula ekuqhekekeni nakokunye ukulimala. Kungakho ukuwa kwebhayisekili kungafaka ingane yakho kubalingisi, kuyilapho ungathatha ukuwa okufanayo futhi ube nomhuzuko - mhlawumbe emzimbeni wakho naku-ego yakho.

Yini iqhaza le-calcium kukho konke lokhu?

I-calcium yiminerali ebalulekile ekwakheni izicubu ezintsha zethambo. Kutholakala kokubili ubisi lwebele nefomula. Futhi uma ingane yakho imelana nokudla imifino yayo enamaqabunga kamuva, mkhumbuze ukuthi i-calcium etholakala kule mifino (kanye nasemikhiqizweni yobisi) iyayisiza ukuba ikhule.

Izinguquko zamathambo aziyeki lapho

Lapho usukhulile, ukuxubana kwamathambo nokukhula kwethambo kuyekile. Amathambo abantu abadala aqinile kakhulu, kodwa alula. Futhi manje njengoba unamathambo akho angama-206, usulungile, akunjalo?

Hhayi, hhayi ngqo. Ngenkathi zibonakala ziqinile futhi zingaguquki, amathambo aqhubeka nenqubo ebizwa ngokuthi ukulungiswa kabusha. (Kepha kuyiqiniso ukuthi inani lamathambo onalo ngeke lishintshe ngokwejwayelekile ngemuva kwaleli phuzu.)

Ukulungiswa kabusha kufaka phakathi ukwakheka kwezicubu ezintsha zethambo kanye nokuwohloka kwethambo elidala libe yi-calcium namanye amaminerali, akhishelwa egazini. Le nqubo yaziwa njenge-resorption, futhi iyingxenye ejwayelekile nenempilo yokusebenza kwamathambo - empeleni, yenzeka kuyo yonke impilo. Kepha ezinganeni, ukwakheka kwamathambo okusha kudlula ukubuyiselwa esikhundleni.

Kunezinto ezithile ezingasheshisa ukulahleka kwethambo. Lokhu kufaka phakathi:

• izinguquko zehomoni ezihambisana nokunqamuka kokuya esikhathini
• ukuphuza ngokweqile
• ukukhula

Isimo esivame kakhulu esithinta ukulahleka kwethambo yi-osteoporosis, edala ukuthi amathambo alahlekelwe ubukhulu bawo futhi abe sengozini yokuqhekeka.

Ake sibe namaqiniso amathambo amnandi

Uhlaka lwamathambo namalunga emzimbeni womuntu luyinkimbinkimbi futhi luyathakazelisa - njengawe. Amathambo ahlangana njengephazili enkulu, futhi ancike ezinhlotsheni ezahlukahlukene zokunyakazisa amalunga kusuka entanyeni nasemhlathini kuya ezinzwaneni.

Amaqiniso amathambo

• Ingxenye yomzimba equkethe amathambo amaningi yisandla. Kwenziwe ukushaywa.
• Amaseli amaningi abomvu namhlophe emzimbeni adalwa ngomnkantsha wethambo.
• I-femur, ethangeni, yithambo elide kakhulu emzimbeni.
• I-stapes, ithambo elimise okwengqamuzana elisekujuleni kwendlebe, liyithambo elincane kakhulu lomzimba.
• Amathambo agcina cishe amaphesenti angama-99 we-calcium emzimbeni wakho futhi akhiwa cishe ngamaphesenti angama-25 amanzi.
• Amathambo akho angena ngokuphelele esikhundleni salo njalo eminyakeni eyi-10 noma ngaphezulu ngokwenza kabusha. Kufana nokulungisa ikhishi lakho, ngaphandle kokuthi elisha libukeka lifana nelidala ngendlela efanayo.
• Kunezinhlobo ezimbili zezinto zethambo: i-cortical, uhlobo oluqinile olucabangayo lapho ufaka isithombe samathambo, no-trabecular, oluthambile nolwesiponji futhi luvame ukutholakala ngaphakathi kwamathambo amakhulu.
• Amanye amathambo aklanyelwe ukumelana kabili noma kathathu nesisindo somzimba wakho.
• Izicubu ze-cartilage azinalo igazi elijwayelekile futhi azivuseleli, ngakho ukulimala kwe-cartilage kungunaphakade. Ngenhlanhla, nazo azivamile kakhulu.

Ukuthatha

Inqubo yokukhula kwamathambo nokuxubana ezinganeni iyamangaza. Futhi ukuze uqiniseke ukuthi amathambo engane yakho ahlala enempilo iminyaka ezayo, kubalulekile ukudlulisa izifundo ezithile ezibalulekile. Phakathi kwazo:

• Thola i-calcium eyanele ekudleni kwengane yakho (kanye neyakho, futhi). Umzimba awuyenzi i-calcium, ngakho-ke yonke i-calcium oyidingayo kufanele isetshenziswe ekudleni noma kuma-supplements. Ukudla okunempilo okunothe nge-calcium kufaka phakathi imikhiqizo yobisi enamafutha aphansi (ubisi, ushizi, iyogathi), imbewu, ama-alimondi, ubhontshisi omhlophe, kanye nemifino enamaqabunga, njengesipinashi nemifino ye-collard.
• Yenza izivivinyo zokuthwala isisindo, njengokuhamba noma ukuphakamisa izinsimbi, ingxenye yenjwayelo yakho ejwayelekile yokuzivocavoca noma umsebenzi womndeni omnandi. Ukuzivocavoca okuhlola ngokuphepha amathambo nemisipha yakho kungasiza ukukhuthaza impilo yamathambo phakathi nokukhula - kodwa akukaze kusheshe kakhulu ukuqala ukucabanga ngalokhu!
• Qiniseka ukuthi uthola uvithamini D owanele ekudleni kwakho noma ngezithako. Uvithamini D usiza umzimba wakho ukumunca i-calcium. Ukuthola amaprotheni anele nakho kubalulekile emandleni amathambo nemisipha yesikhathi eside. Uma ingane yakho ikumangaza ngokumemezela imifino yayo kusenesikhathi, qiniseka ukuthi iyayazi imithombo emihle yamaprotheni ngaphandle kwenyama. (Futhi njalo khuluma nodokotela wezingane ngezinguquko ekudleni.)
