Ehia mau iwi i hānau ʻia ai nā pēpē a no ke aha lākou i ʻoi aku ai i nā mākua?

- He aha nā iwi i hana ʻia, ʻeā?
- Ke hoʻololi nei i ka iwi i ka ulu ʻana o nā pēpē
- He aha ke kuleana o ka puna i kēia mau mea āpau?
- ʻAʻole kū nā kuʻi iwi i laila
- E loaʻa iā mākou kekahi mau mea leʻaleʻa iwi
- ʻIke iwi
- ʻO ka lawe lawe ʻana
He paʻakikī paha e noʻonoʻo i ka nānā ʻana i kahi pēpē liʻiliʻi hānau hou, akā aia ma kahi o 300 mau iwi nā keiki - a ke ulu nei kēlā mau iwi a ʻano hoʻololi i kēlā me kēia lā.
ʻO nā mākua, ma ka ʻaoʻao ʻē aʻe, he 206 iwi, a ma kahi o 15 pākēneka o ko lākou kino kaupaona.
Kali - ua ʻōlelo wale paha mākou he aneane he 100 mau iwi o nā pēpē ma mua o nā mākua? Pehea e hiki ai?
ʻĀ, ʻoiai he paʻakikī a paʻakikī nā iwi, hana maoli ʻia lākou i nā mea ola a me nā puna e kūkulu mau ʻia a hoʻolei ʻia i kou ola.
E nānā pono kākou pehea e wehewehe ai kēia i ka discrepancy ma waena o kahi pēpē a me ʻoe.
He aha nā iwi i hana ʻia, ʻeā?
Hana ʻia ka hapa nui o nā iwi i mau papa o nā ʻaʻa:
- periosteum: ka membrane mānoanoa ma luna o ka iwi o waho
- iwi kuʻi: ka paheʻe, paheʻe paʻakikī i ʻike ʻia i nā iwi o ka iwi iwi
- hoʻopau: iwi like me ka huahu i loko o ka iwi kuʻina
- iwi iwi: ke kumu-e like me nā jelly o nā iwi e hana i nā huna koko.
ʻO ke kaʻina hana o ka ulu iwi i kapa ʻia ʻo ossification. Hoʻomaka ia ma kahi o ka pule ʻewalu o ka hoʻomohala embryonic - nani loa!
ʻOiai nō naʻe, i ka wā hānau, nui nā iwi o kāu pēpē i hana ʻia i ka cartilage, kahi ʻano o nā mea hoʻopili e paʻakikī, akā maʻalahi. ʻO kekahi o nā iwi o kāu mea liʻiliʻi i hana ʻāpana ʻia i ka cartilage e kōkua ai e mālama i ka pēpē maikaʻi a, maikaʻi, palupalu.
Pono kēlā maʻalahi i hiki i nā pēpē ulu ke mimiki i ka wahi paʻa o ka ʻōpū ma mua o ka hānau ʻana. Māmā hoʻi ia no ka makuahine a me ka pēpē ke hiki i ka pēpē ke hana i ka huakaʻi pīhoihoi ma o ke kahawai hānau i ka wā hānau.
Ke hoʻololi nei i ka iwi i ka ulu ʻana o nā pēpē
I ka ulu ʻana o kāu pēpē i ka wā kamaliʻi, e hoʻololi ʻia ka hapa nui o ia cartilage e ka iwi maoli. Akā ua hana ʻia kekahi mea ʻē aʻe, e wehewehe ana no ke aha i lilo ai nā iwi 300 i ka hānau ʻana i 206 mau iwi i ka wā makua.
ʻO ka nui o nā iwi o kāu pēpē e hui pū, ʻo ia ka mea e emi ai ka nui maoli o nā iwi. ʻO ka hakahaka e hoʻokaʻawale ana i nā wēlau o nā iwi ʻelua i ka hopena, he cartilage pū kekahi, e like me kaʻiʻo i loaʻa iā ʻoe i ka piko o kou ihu.
Loaʻa ka fusing o nā iwi i loko o ke kino. Hoʻomaopopo paha ʻoe aia kekahi a ʻoi aku nā wahi palupalu ma waena o nā iwi i ka iwi poʻo o kāu pēpē. Hiki paha i kēia mau "wahi palupalu" ke hoʻonāukiuki iā ʻoe i kahi liʻiliʻi, akā maʻamau maʻamau lākou. Kāhea ʻia lākou he fontanelles, a ma hope e pili lākou i ka ulu pū ʻana o nā iwi.
Hoʻololi ka cartilage me ka iwi i hoʻohui ʻia i ka hoʻomaka ʻana o nā kīʻaha koko liʻiliʻi - i kapa ʻia he capillaries - e hāʻawi i ke koko momona i nā osteoblast, nā hunaola e hana i nā iwi. Hoʻokumu ʻo Osteoblasts i ka iwi e uhi ana i ka cartilage i ka mua a laila hoʻololi hope iā ia.
A laila, ulu ka iwi i nā keiki ma nā wēlau o nā iwi he nui, a he mau pā ulu ko lākou. Hoʻoholo ka mea ulu i kēlā me kēia pā i ka nui hope a me ke ʻano o ka iwi. Ke pau ka ulu ʻana o ke kanaka, pau nā pā ulu.
ʻOi aku ka nāwaliwali o nā pā ulu ma mua o nā ʻāpana ʻē aʻe o ka iwi iwi o kāu keiki, a no laila ʻoi aku ka maʻalahi o ka haki a me nā ʻeha ʻē aʻe. ʻO kēia ke kumu o ka hāʻule ʻana o ke kaʻa paikikala e pae i kāu keiki i ka mea hoʻolei, ʻoiai hiki iā ʻoe ke lawe i kahi hāʻule like a ʻeha wale nō paha - ma kou kino a me kou ego paha.
He aha ke kuleana o ka puna i kēia mau mea āpau?
ʻO ka calcium ka mea waiwai i ka hoʻokumu ʻana o ka iwi iwi hou. Loaʻa ia i ka waiū umauma a me ka haʻilula. A inā kūpaʻa kāu keiki i ka ʻai ʻana i kā lākou lau lau ʻōmaʻomaʻo ma hope, e hoʻomanaʻo iā lākou i ka puna i loaʻa i loko o kēia mau mea kanu (a me nā huahana waiū) e kōkua iā lākou e ulu.
ʻAʻole kū nā kuʻi iwi i laila
I ka wā ʻōpio, ua kū ka pili ʻana o nā iwi a me ka ulu ʻana o ka iwi. Ikaika loa nā iwi mākua, akā māmā. A he ʻoiaʻiʻo i kēia manawa he 206 kou mau iwi, ua hoʻonohonoho ʻia ʻoe, ʻeā?
ʻĀ, ʻaʻole pololei. ʻOiai lākou e kū nei a paʻa a loli ʻole, hele mau nā iwi i kahi hana i kapa ʻia ka hana hou. (Akā he ʻoiaʻiʻo ʻaʻole e loli ka helu o nā iwi āu i loaʻa ma hope o kēia kiko.)
Hoʻopili hou ka remodeling i ka hoʻokumu ʻana o ka iwi iwi hou a me ka haki ʻana o ka iwi kahiko i ka calcium a me nā minelala ʻē aʻe, i hoʻokuʻu ʻia i loko o ke kahe o ke koko. ʻIke ʻia kēia hana ma ke ʻano he resorption, a he maʻa maʻamau a olakino hoʻi o ka hana o ka iwi - ʻoiaʻiʻo, hiki i ke ola holoʻokoʻa. Akā i nā keiki, ʻoi aku ka maikaʻi o ka hoʻokumu iwi hou i ka resorption.
Aia kekahi mau mea i hiki ke wikiwiki i ka nalo ʻana o ka iwi. Pākuʻi ʻia kēia mau mea:
- nā hoʻololi hormonal i pili me ka menopause
- inu lama loa
- makahiki e neʻe nei
ʻO ke kūlana maʻamau e pili ana i ka nalo ʻana o ka iwi ka osteoporosis, ka mea e lilo ai ka iwi i kekahi o ko lākou kiʻiona a lilo i mea maʻalahi i nā haki.
E loaʻa iā mākou kekahi mau mea leʻaleʻa iwi
ʻO ke kumu o nā iwi a me nā hono i ke kino o ke kanaka he paʻakikī a pīhoihoi ia - e like me ʻoe. Kūpono nā iwi e like me ka puzzle nui, a kaukaʻi i nā mākala like ʻole e neʻe i nā hono mai ka ʻāʻī a me ka iwi ā i lalo i nā manamana wāwae.
ʻIke iwi
- ʻO ka ʻāpana o ke kino i piha nā iwi ka lima. Hoʻokumu ʻia ʻo ia i kahi kī nui.
- ʻO ka hapa nui o nā ʻulaʻula a me ke keʻokeʻo o ke kino i hana ʻia i ka iwi o ka iwi.
- ʻO ka femur, aia i ka ʻūhā, ʻo ia ka iwi lōʻihi loa i ke kino.
- ʻO nā stapes, kahi iwi stimulate-shaped aia i loko o ka pepeiao, ka iwi liʻiliʻi o ke kino.
- Mālama nā iwi i ka 99 pākēneka o ka calcium i loko o kou kino a haku ʻia ma kahi o 25 pākēneka wai.
- Hoʻololi piha kou iwi i kēlā me kēia 10 mau makahiki a ʻoi paha ma o ka hana hou ʻana. He ʻano like ia me ka hana hou ʻana i kāu lumi kuke, koe naʻe ka mea hou e like me ka eerily e like me ka mea kahiko.
- Aia he ʻelua mau ʻano mea iwi: cortical, ka ʻano paʻakikī āu e noʻonoʻo ai ke kiʻi ʻoe i kahi iwi iwi, a me ka trabecular, ʻoi aku ka palupalu a me ka spongier a loaʻa pinepine i loko o nā iwi nui.
- Hoʻonohonoho ʻia kekahi mau iwi e kū i ʻelua a ʻekolu paha manawa i kou kaumaha o ke kino i ka ikaika.
- ʻAʻohe o ke koko e hāʻawi mau ai i nā aʻa kino a ʻaʻole hōʻano hou, no laila paʻa mau nā ʻeha cartilage. ʻO ka mea pōmaikaʻi, ʻoi aku ka liʻiliʻi o lākou.
ʻO ka lawe lawe ʻana
He mea kupaianaha ke kaʻina o ka ulu ʻana o ka iwi a me ka fusion. A e hōʻoia i ka noho olakino o nā iwi o kāu keiki no nā makahiki e hiki mai ana, he mea nui e hele i kekahi mau haʻawina nui. I waena o lākou:
- E loaʻa ka nui o ka calcium i ka papaʻai a kāu keiki (a ʻo kāu kekahi). ʻAʻole hana ke kino i ka puna, no laila e pau i ka puna a pau āu e makemake ai i ka meaʻai a i ʻole nā mea hoʻohui. ʻO nā meaʻai momona momona i loko o ka momona me nā huahana waiū momona momona (ka waiū, ka tī, ka yogurt), nā ʻanoʻano, nā ʻalemona, nā pīni keʻokeʻo, a me nā lau lau, e like me ka spinach a me nā collard greens.
- Hana i nā hana kaumaha, e like me ka hele wāwae a i ʻole ke hāpai ʻana i ke kaumaha, kahi ʻāpana o kāu papa hana maʻamau a i ʻole kahi hana ʻohana leʻaleʻa. ʻO nā hoʻoikaika e hoʻāʻo palekana i kou mau iwi a me nā mākala hiki ke kōkua i ka hoʻoikaika ʻana i ka olakino iwi i kou wā makua - akā ʻaʻole hiki ke hoʻomaka e noʻonoʻo e pili ana i kēia.
- E hōʻoia i ka lawa ʻana o ka wikamina D i kāu papaʻai a i ʻole ma o nā mea hoʻohui. Kōkua ka Wikamina D i kou kino e omo i ka puna. ʻO ka loaʻa ʻana o ka protein ka mea nui no ka iwi lōʻihi a me ka ikaika o ka mākala. Inā pīhoihoi kāu keiki iā ʻoe ma ka haʻi mua ʻana i kā lākou vegetarianism, e ʻike pono ʻike lākou i nā kumuwaiwai maikaʻi o ka protein ʻē aʻe i kaʻiʻo. (A kamaʻilio mau me ka pediatric e pili ana i nā loli o ka papaʻai.)
