Ko te mahi o te uaua kiko me ngā momo hanganga

hanga te tinana o te kararehe katoa, me te tangata, kei te ake o ngā momo e whā o te kikokiko: epithelial, io, tūhonohono, me te uaua. I te whakamutunga ka e lāulea ki roto i tenei tuhinga.

Variety o uaua kiko

Ko reira o e toru momo:

• striated;
• maeneene;
• ngakau.

rerekē Functions o te kiko uaua o ngā momo rerekē paku. Na te hanganga rawa.

Kei hea ko te kiko uaua i roto i te tinana tangata?

Uaua kiko o ngā momo rerekē noho wāhi rerekē i roto i te tinana o te kararehe, me te tangata. Ko te kupu,, te ingoa titau rite, kei te hanga i te reira ngakau i roto o te uaua ngakau.

Mai i te uaua kōhiwi striated i hanga uaua kiko.

uaua Smooth raina te kōhao roto, e me te iti. Tenei, hei tauira, whēkau, tōngāmimi, kōpū, puku, me ētahi atu

hanganga uaua o ngā momo rerekē rerekē. I tona korero i roto i te kōrero atu i muri.

Nahea te kiko uaua?

Kei reira o te pūtau nui-rahi - pūtau uaua. hoki e karangatia hoki ratou muka. riro pūtau uaua maha-matua, me te maha pungaraungao - organelles kawenga mō te hanga pūngao.

I tua atu, ko te hanganga o te uaua o te kopa tangata me te kararehe tā te aroaro o te nui iti o te taonga kei roto collagen intercellular, e homai uaua elasticity.

Kia titiro a ki te hanganga me te mahi o te kiko uaua o ngā momo rerekē motuhake.

Ko te hanganga, me te tūranga o te kiko uaua maeneene

whakahaeretia ana tēnei papanga e te pūnaha io autonomic. Na reira, e kore e taea e tetahi te whakaiti i te uaua aau hangaia i papanga maheni.

Kei te hanga e te reira i i te mesenchyme. Ko te ahua o embryonic kiko tūhonohono.

Whakaiti Ko nui iti hohe, me te hohoro tenei kikokiko atu striated.

Maeneene hanga te papanga e o āhua myocytes fusiform ki pito koikoi. pea te roa o enei pūtau i 100 ki te 500 micrometers, me te matotoru - o e pā ana ki 10 micrometers. Ko te pūtau o te kikokiko he mononuclear. Kei te karihi te i roto i te pokapū o te myocyte. I tua atu, pai whakawhanakehia-organelles pērā i pungaraungao me EPS agranular. Ano i roto i te uaua maeneene pūtau kiko e he maha nui o inclusions glycogen, e kėia rāhui o ngā matūkai.

Ko te huānga e whakarato ana i te whakaiti o te uaua kikokiko o nga momo, he myofilaments. Ka taea te hanga ratou o rua pūmua contractile actin me myosin. myofilaments diameter e ngā o myosin, he 17 nanometers, me te hunga e hangaia o actin - 7 nanometers. He hoki myofilaments takawaenga nei diameter ko 10 nanometers. Takotoranga myofibrils ahopou.

Ko te hanganga o tenei momo o te uaua kikokiko hoki ngā kopu wahopūtau o collagen, e whakarato ana kōrero i waenganui i myocytes takitahi.

Functions o te kiko uaua o tenei ahua:

• Sphincter. He e o te kopa uaua maeneene whakaritea i roto i te porowhita ture te ihirangi o te tinana whakawhiti ki tetahi atu ranei i tetahi wahi o te tinana ki tetahi.
• Hōneatanga. takoto te reira i roto i te meka e te uaua maeneene tauturu i te hua ururua puha tinana, me te whai wāhi i roto i te tukanga o te whanautanga.
• Te hanga i te lumen iaia.
• Hanganga o te taputapu ligamentous. Ngā mihi ki a ia, he tokomaha whekau, pērā i whatukuhu, kua tū i roto i te wahi.

Na kia titiro a ki te ahua o te uaua kiko.

Striated

Kei te faaterehia te reira i te taha o te pūnaha io somatic. Na reira, ka taea e te tangata aau whakahaere tenei momo o te uaua. Mai i hanga e te kiko uaua kōhiwi striated te.

Kei tēnei kikokiko o muka. Ko nga pūtau e whai tikanga piri ki te membrane wē he plurality o otaota enei. I tua atu, i roto ratou moni nui o inclusions glycogen. organelles pai whakawhanakehia-pērā i pungaraungao. E tata ki te pūtau contractile o te huānga ratou. E kei tata nga karihi atu organelles katoa, me te painga whakawhanakehia.

Structures roto i heke papanga ripeka-purepure te, he myofibrils. Ratou diameter Ko waenganui i tetahi, me te rua micrometers. Myofibrils noho te nuinga o te pūtau, ka whakanohoia i roto i tona pokapū. Takotoranga myofibrils ahopou. E hanga ana ratou ki runga o te te marama, me kōpae pouri, tauutuutu, e hanga ripeka "Whakahekeheke" papanga.

Functions o te kiko uaua o tenei momo:

• Whakarato i te tinana neke i roto i te wāhi.
• Te kawenga mō te kaupapa o te wahi whanaunga ki ia atu te tinana.
• Ko te kaha ki te mau tonu tūranga o te tinana.
• Whai wāhi i roto i te ture o te pāmahana: te heke uaua kaha, te teitei te pāmahana. A, no te mīti uaua striated kia tīmata ki te kirimana i oke ai. whakamārama ana tēnei i te wiri o te tinana.
• Mahi atu ki te mahi tiaki. Ko rawa pono o te uaua puku, e tiaki maha whekau i te kino tenei.
• Ture rite te taupuni o te wai me te tai.

kiko uaua cardiac

he rite e rua i roto i te striated, a maheni tenei papanga. I tua atu i maheni, e whakaritea ai e te pūnaha io autonomic. Heoi, e holomui te reira rite kaha rite striated.

Kei a ia ko ngā pūtau i huaina cardiomyocytes.

Functions o te kiko uaua o tenei momo:

• Ko kotahi anake: ki te whakarite i te kaupapa o te toto i roto i te tinana.
