He vertebrates nā kānaka, ʻo ia hoʻi he kolamu kuamoʻo kā mākou, a i ʻole ka iwi ʻaoʻao.

Ma waho aʻe o kēlā iwi kuamoʻo, loaʻa iā mākou kahi ʻōnaehana iwi nui i hana ʻia me nā iwi a me nā kāhili a me nā aʻa a me nā liga.

Ma waho aʻe o ka hāʻawi ʻana i kahi anga no kou kino, lawelawe pū nā iwi i nā hanaola biolo nui ʻē aʻe, e like me ka pale ʻana i kāu ʻoka kūloko mai ka ʻeha a me ka mālama ʻana i nā meaola pono.

E heluhelu e ʻimi ai i nā hana like ʻole a me nā ʻano iwi.

He aha ka hana a ka iwi?

Lawe nā iwi i nā hana nui i kou kino, me:

Kākoʻo

Hāʻawi ʻo Bone i kahi anga paʻa a me ke kākoʻo no nā ʻāpana ʻē aʻe o kou kino.

ʻO kahi laʻana, hāʻawi nā iwi nui o nā wāwae i ke kākoʻo i kou kino kiʻekiʻe ʻoiai ʻoe e kū nei. Me ka ʻole o kā mākou iwi, ʻaʻohe o mākou ʻano i wehewehe ʻia.

Neʻe

He mea nui hoʻi nā iwi i ka neʻe ʻana o kou kino, e hoʻoili ana i ka ikaika o nā kuʻina muscle.

Hoʻopili kou mauʻiʻo i kou mau iwi ma o nā tendons. Ke kuʻikahi kou mauʻiʻo, hana kou mau iwi ma ke ʻano he lever ʻoiai e hana ana kāu mau ami i kahi kiko nui.

Hāʻawi ka pilina o nā iwi a me nā mākala i ka nui o ka neʻe ʻana i hiki i kou kino ke hana.

Palekana

Pale pū kou mau iwi i ka hapa nui o kou i loko. ʻO nā laʻana maikaʻi o kēia me ke ala e hoʻopuni ai kou iwi iwi i nā mea e like me kou puʻuwai a me kou māmā a pehea e hoʻopuni ai nā iwi o kou iwi poʻo i kou lolo.

ʻO ka hanauna a me ka mālama ʻana o nā pūnaʻi koko

ʻO nā hunaʻi he nui o kou koko - nā ʻulaʻula, nā ʻulaʻula keʻokeʻo, a me nā platelet - i loko o kou mau iwi. Kapa ʻia kēia hana hematopoiesis, a kū ʻia ia i kahi ʻāpana o kou iwi iwi i kapa ʻia ka ʻulaʻula.

Waihona

Mālama ʻia nā minerala nui, e like me ka puna a me ka phosphorus, i loko o kou mau iwi. Ke makemake nui kou kino i kēia mau kumuwaiwai, hiki iā lākou ke hoʻokuʻu ʻia i kāu kahe o ke koko no ka hoʻohana.

Ma waho aʻe o ka momona ʻulaʻula, loaʻa i nā iwi kekahi ʻano momona o ka momona i kapa ʻia he iwi melemele. ʻO kēia kahi e mālama ʻia ai kahi mea momona. Hiki ke wāwahi ʻia nā momona o kēia kino a hoʻohana ʻia no ka ikehu inā koi ʻia.

5 ʻano iwi

Māhele ʻia nā iwi o kou kino i ʻelima mau ʻano ʻokoʻa e pili ana i ko lākou kinona a me kā lākou hana.

Iwi lōʻihi

E like me ka manaʻo o ko lākou inoa, ʻoi aku ka lōʻihi o nā iwi lōʻihi ma mua o ko lākou ākea. Aia kekahi mau laʻana:

• femur (iwi ʻūhā)
• humerus (iwi lima luna)
• iwi o kou manamana lima a me kou manamana wāwae

Hoʻokumu ka hana o nā iwi lōʻihi i ke kākoʻo ʻana i ke kaumaha o kou kino a me ka hoʻoikaika ʻana i ka neʻe ʻana o kou kino.

Iwi pōkole

He kūlike like nā iwi pōkole a ua ʻano ʻano like me ka pahu. Hiki ke loaʻa nā laʻana i nā iwi o kou mau pulima a me kou kuʻekuʻe wāwae.

Hāʻawi nā iwi pōkole i ka paʻa i ka pulima a me nā kuʻekuʻe wāwae a kōkua pū kekahi i ka neʻe ʻana i kekahi mau neʻe.

Iwi pālahalaha

ʻAʻole pālahalaha nā iwi pālahalaha, akā lahilahi a ʻōwili iki. ʻO nā laʻana o nā iwi pālahalaha e pili ana i kāu:

• iwi iwi
• scapula (iwi poʻohiwi)
• iwi ʻaoʻao

Mālama pinepine nā iwi pālahalaha i ka pale ʻana i kāu nā loko o loko. E noʻonoʻo pehea e hoʻopili puni ai kou mau iwi iwi i kou lolo.

Hiki i nā iwi pālahalaha ke lilo i mau kiko o ka hoʻopili no kou mau mākala. He laʻana maikaʻi kou iwi iwi poʻohiwi o kēia.

Iwi kūpono ʻole

ʻO nā iwi kūpono ʻole o kou kino he mau ʻano like ʻole e paʻakikī pinepine. ʻO nā laʻana me:

• vertebrae
• iwi pelvic
• nā iwi he nui o kou alo

E like me nā iwi pālahalaha, ʻo ka hana o nā iwi kīnā ʻole e pale i nā ʻāpana like ʻole o kou kino. ʻO kahi laʻana, pale kou vertebrae i kou kaula iwi.

Nā iwi Sesamoid

Liʻiliʻi a pōʻai ke ʻano o nā iwi Sesamoid. Loaʻa lākou i loko o ke kino, ka hapanui i nā lima, nā wāwae, a me nā kuli.

ʻO ka mea hoihoi, hiki ke hoʻololi i kā lākou kau ʻana mai kēlā me kēia kanaka. ʻO ka patella (kneecap) kahi laʻana o kahi iwi sesamoid koʻikoʻi i loko o ke kino.

ʻO nā Sesamoids he mau iwi e hana i loko o ka lono a me nā iwi i hoʻopuni ʻia e nā ʻāʻī, kahi e hoʻopili ai i nā mākala i ka iwi. Kōkua lākou i ka pale ʻana i nā kaula o ke kapa komo a haehae a hoʻomaha i ke kaomi ke hoʻohana ʻia kahi ami.

Hāʻawi lākou i kahi pono mechanical i nā mākala a me nā olonā kahi e noho ai lākou.

Nā ʻano kiko iwi

Hoʻokomo ʻia kou mau iwi i ʻelua mau ʻano nāʻaʻa.

Kūpono

ʻO ka iwi kuʻikuʻi ka iwi o waho o ka iwi. Hana ʻia ia e nā papa i hoʻopaʻa paʻa ʻia o ka iwi iwi.

Aia i loko o ka iwi Compact kahi auwai waena e holo ana i ka loa o ka iwi, i kapa pinepine ʻia he auwai Haversian. ʻAe nā ʻalalā Haversian i nā kīʻaha koko a me kekahi ʻalalā e hiki ai i ka iwi.

Spongy

ʻAʻole like ka iwi Spongy me ka iwi puʻupuʻu a ʻano like me ka meli meli. Loaʻa iā ia nā ana e paʻa ai ka iwi ʻulaʻula a melemele paha.

He mea nui ka iwi Spongy no ka neʻe. Inā kūpili kou mau iwi iwi āpau, kaumaha paha ʻoe i ka neʻe ʻana. Kōkua pū ka iwi Spongy e omo i ka haʻalulu a me ke koʻikoʻi mai ka neʻe ʻana.

Nā ʻano ʻāpana iwi

Aia nā ʻano ʻokoʻa o nā hunaola i loko o kou mau iwi.

Nā pūnaewele koʻokoʻo Mesenchymal

ʻO kēia nā hunaola i loaʻa i loko o kou mau iwi. Hiki iā lākou ke hoʻomohala i loko o nā ʻano like ʻole o ke keena, me osteoblast.

Osteoblast

ʻO kēia mau pūnaewele mai nā pūnaewele mesenchymal stem. Hana lākou e waiho collagen a me nā minelala e lilo i iwi makua.

Ke hoʻopau lākou i kēia, hiki i nā osteoblast ke lilo i cell i ka iwi o ka iwi, e ulu a lilo i osteositte, a i make paha i kahi hana kūlohelohe i kapa ʻia ʻo apoptosis.

Osteosit

Hoʻopaʻa ʻia nā osteocytes i loko o ka iwi iwi a ʻo ia ka nui o nā ʻano o nā pūnaewele i nā mākua iwi oʻo. Nānā lākou i nā mea e like me ke koʻikoʻi, ka nui o ka iwi, a me nā mea momona.

He mea nui lākou no ka hōʻailona ʻana i ka wā o ka hoʻoponopono hou ʻana o ka iwi, ke kaʻina o ka resorption iwi a me ka hanauna ʻana o ka iwi iwi hou e hiki ke ukali.

Osteoklas

ʻO nā osteoclasts nā hunaola nui. Hūnā lākou i nā ʻona like ʻole a me nā enzyme e ʻae ai e resorbed kaʻiʻo o ka iwi. Hiki ke hoʻohana ʻia nā mea i resorbed ʻia e hana i kahi iwi iwi hou.

ʻO ka lawe lawe ʻana

Hana ʻoi aku ka nui o kou mau iwi ma mua o ke kākoʻo i kou kino. Mālama lākou i ka neʻe ʻana, hāʻawi i ka pale i nā mea kūloko, a he mea nui ia no ka hoʻokumu ʻana o ke aʻa koko a me ka mālama ʻana i nā mea momona.

Hoʻokaʻawale ʻia kou mau iwi e like me ka nui a me ka hana. Ma loko, loaʻa i nā iwi kekahi ʻano o nā kinona like ʻole a me nā hunaola. Hana pū kēia mau mea āpau i ka hana ʻana i kou mau iwi i nā ʻāpana multifunctional ʻo lākou ia.
