ʻŌnaehana muscular: hoʻokaʻawale a me nā ʻano o nā mākala
Anter
Kūlike ka ʻōnaehana muscular i ka pūʻulu o nā mākala i loko o ke kino e ʻae i nā neʻe e hoʻokō ʻia, a e hōʻoia hoʻi i ke kūlana, ka paʻa a me ke kākoʻo o ke kino. Hoʻokumu ʻia nā mākala e kahi ʻāpana o nā olonā, nā myofibril, i hoʻonohonoho ʻia i nā pūʻolo a hoʻopuni ʻia e nāʻiʻo.
Hiki i nā mākala ke hana i ka neʻe o ka contraction a me ka hoʻomaha a ʻo kēia ka mea makemake i ka hana o nā neʻe o kēlā me kēia lā, e like me ka hele wāwae, ka holo ʻana, ka lele ʻana, ka noho ʻana, a me nā mea ʻē aʻe e pono ai ka hana pololei ʻana o ke kino, e like me kaapuni i ke koko, hanu a hoʻokō i ka digestion.
Hoʻokaʻina o nā mākala
Hiki ke hoʻokaʻawale ʻia nā mākala e like me kā lākou hanana, hana a me nā hiʻohiʻona contraction. Wahi a kā lākou ʻano contraction, hiki i nā mākala ke:
- Nāʻaʻa, ke hoʻohui ʻia kāna contraction e ka ʻōnaehana makaʻu, i hoʻohuli ʻia e ka makemake o ke kanaka;
- Hana manawaleʻa, kahi a ka contraction a me ka hoʻomaha ʻana o ka mākala e pili ʻole ai i ka makemake o ke kanaka, e hana mau ʻia ana, e like me ke ʻano o ka mākala puʻuwai a me nā mākala i loko o ka ʻōpū e ʻae ai i nā neʻe peristaltic, no ka laʻana.
Wahi a kā lākou hana, hiki iā lākou ke hoʻokaʻawale ʻia i:
- Nā Agonists, ka mea ʻaelike me ka pahuhopu o ka hoʻokumu ʻana i ka neʻe;
- ʻO Synergists, ka mea ʻaelike ma ke ala like me nā agonists, e kōkua ana e hana i ka neʻe;
- ʻO Antagonists, ka mea kūʻē i ka neʻe i makemake ʻia, ʻo ia hoʻi, ʻoiai e hana ana nā mākala agonist i ka neʻe ʻana o ka contraction, hoʻolaha nā mea antagonists i ka hoʻomaha a me ka hoʻolōʻihi ʻana o ka mākala, e ʻae ana i ka neʻe i kahi ala i hoʻohui ʻia.
Hoʻohui ʻia, e like me nā ʻano o ke kūkulu ʻana, hiki ke hoʻokaʻawale ʻia nā mākala me he laumania, iwi a me ka puʻuwai. Pili pololei kēia mauʻiʻo me ka ʻōnaehana i mea e ʻae ai i ka neʻe ʻana i kahi ala pololei a me ka hoʻohui pū.
ʻAno Muscle
Wahi a ke ʻano, hiki ke hoʻokaʻawale ʻia kaʻiʻo o ka ʻūhā i ʻekolu ʻano like ʻole:
1. ʻO ka mākala Cardiac
ʻO ka puʻuwai puʻuwai, i kapa ʻia hoʻi he myocardium, ʻo ia ka mākala e uhi ana i ka puʻuwai a ʻae i nā neʻe ʻana o kēia meaola, e ʻoluʻolu i ka lawe ʻana o ke koko a me ka oxygen i nā mea ʻē aʻe a me nā ʻano o ke kino, e mālama ana i ka hana kūpono o ke kino.
Hoʻokaʻawale ʻia kēia mākala ma ke ʻano he hana ʻole, no ka mea, hoʻokō ʻia kāna hana me ka nānā ʻole i ka makemake o ke kanaka. Eia hou, he striations kona, a hiki ke kapa ʻia hoʻi he striatum cardiac, a he elongated a me branched keena e ʻaelike ikaika a me ka rhythmically.
2. Mākala mānoanoa
ʻO kēia ʻano mākala he kaohi hoʻoikaika ʻole a lohi hoʻi a hiki ke loaʻa i ka paia o nā ʻāpana hakahaka e like me ka ʻōnaehana digestive, bladder and artery, no ka laʻana. ʻAʻole like me ka puʻuwai puʻuwai, ʻaʻohe nā kaha o kēiaʻiʻo a, no laila, kapa ʻia he laumania.
3. Muscle iwi
ʻO ka mākala skeletal kekahi ʻano o nā mākala striated, eia naʻe ʻokoʻa ka ʻano o nā mākala ʻē aʻe, he manawaleʻa manawaleʻa ia, ʻo ia hoʻi, no ka neʻe ʻana, pono i ke kanaka e hāʻawi i kēia hōʻailona no ka ʻae o ka ʻiʻo. Hoʻopili kēia ʻano nāʻiʻo i nā iwi ma o nā ʻāʻī, e ʻae ai i ka neʻe ʻana o nā mākala o ka lima, nā wāwae a me nā lima, no ka laʻana.
