Ko te mahi o te kiko uaua maeneene. kiko uaua Whakaene: hanganga

Papanga - he huinga o te hanganga pūtau rite, e faaite i ngā āhuatanga noa. Tata e tito kaiao multicellular katoa o ngā momo rerekē o te kopa.

whakarōpū

I roto i te kararehe, me te tangata e kitea i roto i te tinana e whai ake nei ngā momo kiko:

• epithelial;
• io;
• huinga;
• uaua.

i ngā ēnei rōpū mō te maha o ngā momo. Ko te kupu, ko te kiko tūhonohono he ngako, ngohe, wheua. Kei roto hoki i te toto me te tīpona. kiko epithelial reira he taea hoki te taratahi te kotahi-apa, me te maha-apa, i runga i te hanganga o te pūtau rānei, papa rawa, pūtoru, epithelium porotakaroa, a na i runga i. D. Nervous ko tetahi anake ahua. Ka kia kōrero te momo o te uaua kikokiko i roto i te taipitopito ake i roto i tenei tuhinga.

Ngā momo o uaua kiko

I roto i te tinana o te kararehe katoa o te huna hoki i ona momo e toru:

• uaua maeneene;
• striated uaua;
• kiko uaua cardiac.

Ko te mahi o te kiko uaua maeneene e rerekē i te hunga o te striated me ngakau, na e rua ia me te hanganga. Kia whakaaro o roto i te kōrero atu te hanganga o ia momo o uaua.

āhuatanga General o te uaua kiko

Mai te katoa e toru ko te momo kotahi, i ratou he rota i roto i te noa.

pūtau uaua huaina myocytes, muka ranei. Tei runga i te momo o te kopa, kia whai ratou i te hanganga rerekē.

Uaua kiko, whakaahua o e taea te kite i raro, e tata kahore taonga intercellular.

Ko tētahi atu āhuatanga noa o ngā momo katoa o te uaua, ko te e taea te heke ratou, Heoi, i roto i ngā momo rerekē, puta takitahi tenei tukanga.

āhuatanga myocytes

Pūtau kiko uaua maeneene, rite te striated me cardiac whai āhua elongated. I tua atu, to ratou he organelles motuhake i huaina myofibrils, myofilaments ranei. Kei roto ratou pūmua contractile (actin, myosin). E tika ana ki te whakarite i te kaupapa o uaua ratou. He mahi uaua fie, motu ke i te aroaro o pūmua contractile, ko ano hoki te aroaro o katote konupūmā i roto i te pūtau. Na reira, kohi iti nui ranei o kai ki te ihirangi tiketike o tenei huānga kia meinga arā uaua - e rua maeneene me te striated.

I tua atu, pūtau hakari kotahi te pūmua motuhake - myoglobin. He mea tika ki te kōrero ki te hāora, me te rokiroki i te reira.

No nia i organelles, motu ke i te aroaro o motuhake myofibrillar mō te ihirangi kiko uaua ko reira he maha nui o ngā pungaraungao i roto i te pūtau - dvumembrannyh organelles kawenga mō te respiration pūkoro. Ko te kore e maere tenei, kia rite ki te muka uaua ki te whakaiti i te nui nui o te pūngao me te hua i roto i respiration i pungaraungao.

I roto i te tahi mau myocytes e kitea i roto i neke atu i te kotahi matua hoki. He āhuatanga o ngā pūtau uaua striated e kia roto e pā ana ki e rua tekau otaota, a ētahi wā tenei ahua tae ake ki te kotahi rau tenei. Ko e tika ana ki te meka i hanga e te muka o te uaua striated te o te maha pūtau, ka ngā ki tetahi tenei.

Ko te hanganga o te uaua striated

ka karanga tenei momo o te papanga te uaua kōhiwi. Muka o tenei momo o te roa uaua, kohia ki paihere. kia ēnei pūtau maha ngā henimita te roa (ki runga, ki te 10-12). Kei roto ratou maha karihi, pungaraungao me myofibrils. Ko te kōwae hanganga taketake o ia myofibril o kikokiko striated - sarcomere. Kei a ia ko te pūmua contractile.

Ko te āhuatanga matua o tenei uaua ko e taea te whakahaere i taua aau, i roto i te rerekē ki te maeneene me te cardiac.

Kua piri ana te muka o te papanga ki wheua mā tendons. Ko te aha i huaina enei e uaua kōhiwi, me te.

Hanganga o te kiko uaua maeneene

uaua maeneene ngohi te etahi o nga whekau pērā i te paru, kōpū, tōngāmimi, me oko toto. I tua atu, i whai ahua ai ratou sphincters me tuhonohono.

e kore te mea rite te roa rite te striated muka uaua Smooth. Ko he nui atu i roto i te take o uaua kōhiwi tona matotoru. Pūtau maheni kiko uaua i veretonopodobnoy puka, nui atu i filamentary rite myocytes striated.

Structures e obesechivayut hukihuki uaua maeneene, ka karanga protofibrils. I roto i te rerekē ki te myofibrils, to ratou he hanganga ohie. Ko te rauemi e hanga i nei e ratou - te pūmua contractile taua actin me myosin.

Pungaraungao i roto i myocytes he iti iho i te i roto i te pūtau o te striated me cardiac hoki uaua maeneene. I tua atu, i roto ratou tetahi anake karihi.

Āhuatanga o te uaua ngakau

Ētahi kairangahau tautuhi reira rite te momo o te kiko uaua striated. Ko te tino to ratou muka te rota rite tahi. pūtau ngakau - cardiomyocytes - Kei roto hoki otaota maha, he maha nui o myofibrils me pungaraungao. Tenei papanga, me te uaua kōhiwi, taea ki te kia heke nui tere me te kaha atu i te uaua maeneene ko.

Heoi, ko te āhuatanga matua wehe i te uaua ngakau i striated, he e kore e taea te whakahaere i te reira aau. Whakaiti i te reira anake tupu aunoa, pera i roto i te take o te uaua maeneene.

Ka rite ki te wahi o te kiko ngakau, i roto i te tua ki ngā pūtau angamaheni e hoki hakari cardiomyocytes secretory. e kore e ratou i roto i myofibrils me kahore e iti. Ēnei pūtau atriopeptina otvesayut mō te hanga o te taiaki, i te mea faufaa mo te ture o te pēhanga toto me te mana rōrahi toto.

Taumahi o uaua striated

Ratou mahi matua - ki te neke i te tinana i roto i te wāhi. Ko reira ano hoki te kaupapa o nga wahi whanaunga ki ia atu te tinana.

I roto i te tahi atu mahi kia tuhia ai uaua striated te pupuri wai āraitia te taupuni me te tai. I tua atu, e mahi ratou i te tūranga paruru, ngā ki te faatura ki te uaua puku ki te ārai kino pūkaha ki te whekau.

Ka taea e hoki te mahi kia kiia i roto i te ture o te pāmahana o te musculature striated, rite puta kukuwhatanga o te wera nui ki te hukihuki uaua kaha. Ko te aha, no ka timata peremerzanii uaua ki te wiri i oke ai.

Ko te mahi o te kiko uaua maeneene

Musculature o tenei momo mahi hōneatanga mahi. takoto te reira i roto i te meka e pana nga uaua maeneene o te whēkau te kumete ki te wahi o to ratou whakakorenga i te tinana. Ano hoki, whakakitea tenei tūranga te i whanau, ina pana te hua o te tinana te uaua maeneene o te kōpū.

E kore e iti nga mahi o te kiko uaua maeneene. Ano he wahi nui o to ratou sphincter. Papanga o tenei momo e hanga e e uaua porowhita motuhake e taea occlude me tuwhera. He Sphincters reira i roto i te mimi, i roto i te punuatuna, i waenganui i te puku me te pū kai, te au tōngāmimi, i roto i te whatupango.

Ko tētahi atu wāhi nui o te uaua maeneene - te hanganga o te taputapu ligamentous. He mea tika ki te mau tonu i te tūranga tika o nga whekau. Na roto i te e tukupu te reo o enei uaua prolapse o etahi whekau taea puta.

I tenei mahi mutunga uaua maeneene.

Whakaaro o te uaua ngakau

Here, i roto i te parau tumu, i reira he mea ki te mea motuhake. Ko te mahi matua, me te anake o tenei kikokiko - te whakarato i te tohanga toto i roto i te tinana.

Conclusion: Ko te rerekētanga i waenganui i nga momo e toru o te uaua kiko

Hoki whākinga o te take tapaea tatou he tepu:

Ko te nga āhuatanga taketake katoa o striated, kiko uaua maeneene me te cardiac. Na ko mōhio ki o ratou mahi, hanganga, me nga rerekētanga matua me ngā ōritenga koutou.
