Te rerekētanga i waenga i te uaua whiri me te uaua maeneene
Ko te uaua he kiko tinana e kawe ana i te nekehanga o ngā wāhanga rerekē o te tinana i roto i ngā mea ora. I roto i te pūnaha uaua me ngā hononga o te tangata, ka taea te whakarōpū i ngā uaua ki ngā momo matua e toru: te uaua angaanga, te uaua maeneene, me te uaua ngākau. Ahakoa he mahi nui tā ēnei momo uaua katoa ki ngā mahi a te tinana, ka arotahi tēnei tuhinga ki ngā rerekētanga matua i waenga i te uaua angaanga me te uaua maeneene, tae atu ki ō rātou hanganga, mahi, tauwāhi, me te tikanga mahi.
Hanganga Makaroiti
Uaua Tūtae:
E mōhiotia ana hoki te uaua whakarara ko te uaua angaanga nā te mea e piri ana ki ngā wheua. He āhua motuhake tōna ina tirohia i raro i te karuārai - he āhua whakarara, he "whakarara" rānei. Nā te whakaritenga ōrite o ngā sarcomeres tēnei whakarara, arā, ngā wāhanga o ngā muka uaua kei roto ngā miro actin me myosin kua whakarārangihia pai.
Ko te uaua whakarara he muka uaua roa, porotaka, he maha ngā karihi kei te taha o te pūtau. He rerekē te rahi o ēnei muka, engari he maha henimita te roa, ā, tae atu ki te 100 maikiromita te whānui.
Ngā Uaua Maeneene:
He rerekē te hanganga o te uaua maeneene. He rite te āhua o ngā pūtau uaua maeneene ki te miro, he whaiti ngā pito, ā, kotahi te pūtake kei waenganui o te pūtau. Kāore he rārangi e kitea ana i roto i te uaua maeneene nā te mea kāore i te rite te whakaritenga o ngā sarcomeres me ngā miro whakawhāiti.
He iti ake te rahi o ngā pūtau uaua maeneene ki te whakaritea ki te uaua whiri, e 20-200 maikiromita te roa, ā, he iti ake anō hoki te whānui.
Te Mahi me te Tikanga Mahi
Uaua Tūtae:
Ko ngā uaua whiri te kawenga mō ngā nekehanga ā-tūao, ā-whakaaro rānei. Hei tauira, ina hikoi, ina oma, ina hiki taumaha rānei tātou, ka mahi ngā uaua whiri. Ko te tikanga o te whakahekenga o ngā uaua whiri ka whakahaeretia e te pūnaha io tinana, ka tukuna ngā tohu hiko mai i te roro, i te taurakira rānei ki ngā muka uaua mā roto i ngā neuron motuka.
Ko te whakawhāititanga o te uaua striated e pā ana ki te taunekeneke i waenga i ngā miro actin me te myosin i roto i te sarcomere. Ka tīmata tēnei tukanga me te tohu e whakaoho ana i te tukunga o ngā iona konupūmā, ka herea ki te troponin, he pūmua e āwhina ana ki te whakahaere i ngā taunekeneke actin-myosin. Nō reira, ka paheke ngā miro myosin i runga i ngā miro actin, ka puta te whakawhāititanga o te muka uaua.
Ngā Uaua Maeneene:
Ko ngā uaua maeneene ia, e whakahaere ana i ngā nekehanga koretake, koretake rānei. Kei roto i ngā pakitara o ngā whekau o roto pēnei i te whekau, ngā uaua toto, te pūhā, me te kōpū ēnei uaua. Ko te pūnaha io aunoa, e wehea ana ki ngā pūnaha io atawhai me ngā pūnaha io paraha, e whakahaere ana i ngā whakahekenga uaua maeneene.
Me whai i ngā katote konupūmā te whakawhāititanga o te uaua maeneene engari kāore e uru te troponin. Engari, ka herea ngā katote konupūmā ki te calmodulin, he pūmua whakahaere. Kātahi ka whakahohehia e tēnei matatini calmodulin te whākōkī myosin light chain kinase (MLCK), e whakapūpū ana i te myosin, ka taea ai e ia te taunekeneke ki te actin me te whakaputa i te whakawhāititanga.
Tauwāhi me te Tohatoha
Uaua Tūtae:
Ko ngā uaua whiri e kitea ana e piri ana ki ngā wheua puta noa i te tinana, mai i ngā uaua nui pēnei i te quadriceps ki ngā uaua iti i te nikau o te ringa. E hono ana ia uaua whiri ki tētahi uaua, he kiko honohono kaha e hono ana i te uaua ki te wheua, e whakarato ana i te whānuitanga o te nekehanga.
Ngā Uaua Maeneene:
E ai ki te kōrero i mua ake nei, kei roto i ngā pakitara o ngā whekau o roto ngā uaua maeneene. Kei roto i ngā wāhi pērā i ngā pakitara o te ara kai, ngā oko toto, te ara mimi, te trachea, me te pakitara kōpū i roto i ngā wāhine. Ko tā rātou mahi matua he whakahaere i te whānui me te peristalsis, arā, ngā nekehanga porowhita auau e āwhina ana ki te pana i ngā ihirangi mā roto i ngā awaawa, i ngā ngongo rānei.
Te Whakahaere Io
Uaua Tūtae:
Ko te pūnaha io matua e whakahaere ana i te mana whakahaere o te uaua angaanga. Ka whakapūmauhia e ia angaanga he maha o ngā muka uaua, ka hangaia he mea e mōhiotia ana ko te waeine angaanga. Ko te urupare a te uaua angaanga ki ēnei tohu o te angaanga he tino tere, engari ka ngenge wawe mēnā ka whakamahia tonutia mō ngā wā roa me te kore e nui te okiokinga.
Ngā Uaua Maeneene:
Ko te pūnaha io motuhake te mea e whakahaeretia ana te uaua maeneene, e mahi ana i waho o te mana whakahaere o tō tātou hinengaro. He puhoi ake te urupare a te uaua maeneene ki ngā tohu io i te uaua kikokore, engari he ātete ake ki te ngenge. He maha hoki ngā wā ka pāngia te whakahekenga o te uaua maeneene e ētahi atu āhuatanga matū pēnei i ngā homoni me ngā matū ā-rohe.
Pūngao me te Pūngao
Uaua Tūtae:
He pai te whakamahi a ngā uaua kikokore i te pākia o te tinana i roto i te tinana, engari ka taea hoki te huri ki te pākia o te tinana i raro i ngā āhuatanga kore-hāora, pērā i te wā e kaha ana te whakakori tinana. Hei tautoko i te whakakori tinana tere, nui te pūngao, ka rongoa e rātou he nui te glycogen, ka taea te wawahi hei hukahuka.
Ngā Uaua Maeneene:
Ko ngā uaua maeneene e whakawhirinaki ana ki te pākia o te tinana kia tutuki ai ō rātou hiahia pūngao. Nā te mea kāore e hiahiatia he whakaheke tere, kaha pērā i ngā uaua whiri, he iti ake te hiahia pūngao o ngā uaua maeneene, ā, ka taea te pupuri i te āhua pākia pumau mō ngā wā roa.
Te Whakaora me te Whakaora
Uaua Tūtae:
Ko te whakaoranga o ngā uaua striated e whakawhirinaki ana ki ngā pūtau amiorangi, he momo pūtau take kei waenganui i te kiriuhi raro me te sarcolemma o ngā muka uaua. I muri i te whara, ka taea e ngā pūtau amiorangi te whakanui me te hono atu ki ngā muka uaua hei whakatika, hei whakakapi rānei i ngā kiko kua pakaru. Heoi, he iti noa iho te kaha o tō rātou whakaora, ā, ka roa pea te tukanga whakaora.
Ngā Uaua Maeneene:
He nui ake te kaha o te uaua maeneene ki te whakaora i te uaua kikokore i te uaua kikokore. Ka taea e ngā pūtau uaua maeneene te whakaputa uri me te wehewehe hei whakatika me te whakakapi i ngā kiko kua pakaru. Hei tauira, i raro i ētahi āhuatanga ā-tinana, pērā i te hāputanga, ka taea te piki ake te maha o ngā pūtau uaua maeneene i roto i te pakitara kōpū hei whakatutuki i ngā hiahia mahi kua piki ake.
Whakamutunga
Ahakoa he mea nui ngā uaua kikorangi me ngā uaua maeneene mō ngā mahi tinana rerekē, he maha ngā rerekētanga i waenganui i a rāua, mai i te hanganga me te mahi tae atu ki ngā tikanga mahi. Ko ngā uaua kikorangi, me ō rātou hanganga kikorangi me te mana whakahaere tūao, te kawenga mō ngā nekehanga tere, kaha, ko ngā uaua maeneene ia, me ō rātou hanganga kore-kikorangi me te mana whakahaere tūao, te kawenga mō ngā nekehanga puhoi, pumau i roto i ngā whekau o roto. Mā te mārama ki ēnei rerekētanga ka āwhina i a tātou kia mārama ake ki te mahi a ō tātou tinana me te tautoko a ngā momo kiko uaua rerekē i ō tātou oranga o ia rā.
