Kiko uaua maeneene: hanganga āhuatanga. Ko te āhuatanga o te kiko uaua maeneene

te kopa kararehe te mahi i te mahi tino nui i roto i te tinana o mea ora - puka me te aho okana me ngā pūnaha katoa. O ngā faufaa i roto i enei uaua kua ara, pera tona faufaa i roto i te hanganga o te waho, me te kōhao i roto o nga wahi hanganga o te kaupapa matua tinana. Ka titiro tēnei tuhinga i te mea i te kiko uaua maeneene, rawa te hanganga o ona āhuatanga.

Ngā momo o enei kopa

Te rauropi kararehe he momo uaua iti:

• transversely whakahekeheke;
• kiko uaua maeneene.

i to ratou ake ngā āhuatanga āhuatanga o te hanganga, ngā mahi e rua o ratou, a whakaaturia te āhuatanga. I tua atu, e mea ohie ki te wehewehe i waenganui ia ratou. I muri i te katoa, ka whai e rua ratou ake tauira ahurei, i hanga nei e na roto i te hanga wahi o nga wae pūmua o ngā pūtau.

Kei te wehea pai Striated ki e rua ngā momo matua:

• kōhiwi;
• ngakau.

Ko te ingoa ano whakaata te wāhi matua o te wāhi o te tinana. He tino nui ona āhuatanga, no te mea ko tenei te musculature whakarato te hukihuki o te ngakau, te kaupapa o wahi me te tahi atu wahi neke katoa o te tinana. Heoi, uaua maeneene, me te kore iti nui. He aha e ona āhuatanga, whakaaro atu.

I roto i te whānui, e taea te kite i te reira e te mahi pai-ruruku anake, whakamana e te kiko uaua maeneene me te striated, tuku i te tinana katoa ki te mahi pai. Na reira, ki te whakatau atu iti nui o ratou ranei e taea.

Maheni kiko uaua: hanganga āhuatanga

Basic āhuatanga rerekē o tenei hanganga takoto i roto i te hanganga me te hanganga o ona pūtau - pūtau uaua. Ka rite ki tetahi atu, i hanga tenei papanga e te rōpū o ngā pūtau e he rite i roto i te hanganga, ngā āhuatanga, hanganga me ngā mahi whakamana. Ka taea te whakaahuatia ngā āhuatanga noa o te hanganga i roto i te torutoru kōwae.

1. karapotia ia pūtau e te TANGLE tangotango o muka kiko tūhonohono, e titiro rite te capsule.
2. Ia kōwae hanganga raru ki te tahi atu, e tata ngaro nga wāhi intercellular. Tenei ka taea te papanga katoa ki te kia Kikī, hanganga me te mārō.
3. Rerekē ritenga striated, kia tenei hanganga e titoa o ngā pūtau o te āhua taurite.

Tenei, o te akoranga, e kore nga āhuatanga katoa e whai kiko uaua maeneene. Āhuatanga o te hanganga, i rite whakaritea kua teka i roto i myocytes ratou, o ratou mahi, me te hanganga. Na reira, i raro i te take ka reira e kōrero i roto i te taipitopito nui.

myocytes uaua Whakaene

Ko o āhua rerekē Myocytes. Ka rerekē i runga i te wāhi i roto i te okana ngā, taea e ratou:

• porotītaha;
• fusiform elongated;
• häunga;
• Tukanga.

Heoi, i roto i tetahi take, he rite ki a ratou te hanganga whānui. Kei roto ratou organelles pērā i:

• pai whakahuatia a te mahi pungaraungao;
• Golgi matatini;
• matua, atu elongated i roto i te āhua;
• kiriuwhi;
• lysosomes.

Noatia, tikanga me inclusions cytoplasm hoki reira. Te mea faahiahia, hipoki waho myocytes uaua maeneene plasmolemma kore anake membrane (basal) engari. E whakarato ana ratou ki te whai wāhi atu ki te whakapā atu i ia atu.

Enei āhuatanga hanga te whakapā tuu kiko uaua maeneene. Whakapā i te wahi e kiia te nohonga. Na roto ratou, me te roto i te kōputaputa, i roto i enei wahi e wātea ana i roto i te membrane, tuku te pini e i waenganui i ngā pūtau, utu mōhiohio, rāpoi wai me ētahi atu pūhui.

Tera atu ano tetahi āhuatanga rerekē, e kua te kiko uaua maeneene. Āhuatanga o te hanganga o ona myocytes e whai kore katoa o ratou te mau hopearaa io. Te aha e mea nohonga kia nui. Ko nga mea katoa e kore e kotahi pūtau noho kahore innervation, a taea te tuku i te torohaki roto i te hanganga i muri ki runga ki te papanga.

E rua ngā momo taketake o ngā pūtau uaua.

1. Secretory. Ratou mahi matua ko te whakatupuranga me te haaputuputuraa o granules glycogen, te whakaū i te plurality o polysomes pungaraungao me wae ribosomal. Ko te ingoa o te hanganga ahu i te pūmua i roto i reira. Tenei contractile kakawaea actin me ngā whenu pūtōtepe. Kei te maha paetata ēnei pūtau i te taha o te kiko.
2. Maheni muka uaua. A ani i te puka o ngā hanganga muka-āhua elongated kei roto i te karihi porotītaha neke ki te waenganui o te whare herehere. Ko tētahi atu ingoa leyomiotsity. Āhuatanga e te meka e whai ratou he rahi nui. matūriki ētahi tinana uterine ake ki te 500 microns! Ko te tino he ahua nui i roto i te papamuri o te tahi atu pūtau katoa i roto i te tinana roa anake te hua manu tenei.

Ko hoki mahi uaua maeneene i roto i te meka e synthesize ratou te pūhui e whai ake nei:

• glycoproteins;
• procollagen;
• elastanes;
• taonga intercellular;
• proteoglycans.

Tahi mahi ruruku me te pāhekoheko momo whakaritea myocytes me whakarato ratou hanganga whakahaere i te kiko uaua maheni.

Ko te take o tenei uaua

hanganga Pūtake o tenei momo i roto i te uaua tinana atu i te kotahi. i reira e toru ngā kōwhiringa matua mo te takenga. E whakamārama ana tēnei i te rerekētanga, e kua te hanganga o te kiko uaua maeneene.

1. takenga Mesenchymal. Ko te wahi nui o te muka maheni. Ko reira no te mea o te mezenhimi i hanga tata te kopa katoa e raina te roto o nga whekau tuwhera.
2. takenga Epidermal. Ko te ingoa ano korero e pā ana ki te localization o ngā pae - repe kiri katoa me o ratou aerodynamics. E hanga e ratou e muka maeneene he tae taua kē. Werawera, huware, waiu, roimata - enei repe te huna hoki he ngaro e tika ana ki te ritenga myoepitheliocytes pūtau - matūriki hanganga o te tinana whakaaro.
3. takenga Neural. E paetata peheé muka i roto i te kotahi wahi ngā - Iris ko tetahi o te kiriuhi kanohi. innervated Tuhinga whakarahi o te tauira ranei kei te ka whakahaeretia e enei pūtau uaua maeneene.

Ahakoa te huru tupuraa rau, te hanganga ā-me ngā āhuatanga o kawea katoa momo pūtau i roto i te kikokiko i raro i whakaarohia noho tata te taua.

Ko te āhuatanga matua o te kikokiko

Āhuatanga uaua maeneene hāngai ki te hunga mo te striated. I roto i tenei e tahoê ratou. Ko ratou:

• kawe ia;
• excitability;
• lability;
• contractility.

I te wa ano i reira he ano he āhuatanga tika motuhake. Ki te taea hohoro nga uaua kōhiwi striated holomui (te pai faahoho'ahia tenei i te faaati i roto i te tinana tangata), ka taea e koe maeneene hoki te wa roa tū i roto i te āhua kōpeke. Ano, e kore e ngohengohe ki te pai ai, me te hinengaro o te tangata ona mahi. Mai kaiwhakawhiwhi reira te pūnaha io autonomic.

He āhuatanga tino nui ko te kaha ki te pōturi toronga wā roa-(whakaiti) me te whakangā taua. Na, e hāngai ana tenei i runga i te mahi o te tōngāmimi. I raro i te mahi o te inu koiora (tona ihirangi) he reira e taea ki te kia totoro a ka holomui. E kapi katoa ona taiepa ki uaua maheni reira.

pūmua pūtau

Kei kikokiko Myocytes whakaaro maha pūhui rerekē. Heoi, ko te nui tino o enei, e whakarato ana te mahi o te hukihuki, me te whakangā, he rāpoi ngota pūmua tika. O ratou kitea konei:

• kakawaea myosin;
• actin;
• nebulin;
• connectin;
• tropomyosin.

Kei te nuinga o ēnei wāhanga kei roto i te cytoplasm o ngā pūtau taratahi i ia atu, kahore hanga māpele. Heoi, i roto i etahi whēkau i roto i nga kararehe āhua paihere ranei whenu, ka karanga myofibrils.

Wāhi i roto i te kikokiko o enei kurupae nuinga roa. Rua kakawaea myosin me actin. Ko te hua ko te whatunga i roto i nei e mea whatu nga pito etahi taha ki atu rāpoi ngota pūmua. He mea nui hoki te whakaiti tere, me te tika o te papanga katoa.

whakaiti takekore ko e whai ake: kia rite ki te wahi o te taiao ā-o te pūtau i vesicles pinocytic, e tika kei katote konupūmā. A, no te tae mai i te pana io, korero e pā ana ki te hiahia ki te whakaiti i tenei mirumiru huarahi te fibril. Ka rite ki te hua, te konupūmā katote actin hōhā me ia kōkiritanga hohonu i waenganui i nga kakawaea o myosin. arata'i tenei ki te karapotinga o te wē membrane me rite ki te hua o te myocyte iti te.

kiko uaua Whakaene: tuhi

Ki te kōrero tatou e pā ana ki te kiko striated, kei te ngāwari mohio ai e striations. Ko konei rite e whakaaro tatou te hanganga, ka tenei e kore e tupu. He aha te mea tino rerekē atu i tona hoa tata tauira uaua maeneene? Ko e tika ana ki te aroaro me te wāhi o te wāhanga pūmua i roto i te myocytes tenei. Hei wāhanga o te maheni myofibrils uaua ngangana o rerekē āhua paetata huru, me kahore whakaritea kāwanatanga whakahau.

Ko Ko te aha te tauira papanga ko noa e kore e wātea. I roto i te kakawaea actin striated ä whakakapi e te ripeka-myosin. Ko te hua ko te pikitia - striation, e tika ana ki nei whiwhi te papanga tona ingoa.

I raro i te karu, titiro papanga maeneene rawa maeneene me te kaunuku, te whakawhetai ki piri pātata ki ia atu ōna whakaritea myocytes elongated.

wāhi mokowā i roto i te tinana

kiko uaua maeneene hanga he maha tika nui o whekau nui i roto i te tinana kararehe. Na, i hanga e ia:

• whekau;
• kikokiko;
• momo katoa o oko toto;
• mate pukupuku;
• whekau puha o te pūnaha;
• wahi romahā;
• wahi o te analyzer ataata;
• whēkau o te pūnaha kūnatu.

Oia mau, e tino kanorau, me te nui o nga localization o kikokiko i raro i whiriwhiria. I tua atu, kia tuhia te reira e taua puka i roto i te uaua te nuinga aua tinana e e ngohengohe ki te automaticity i whakahaere.

Methods whakaora

kiko uaua maeneene hanga he hanganga tika nui e whai i te kaha ki te whakaora. Na reira, Kei te āhuatanga i reira e rua huarahi matua i roto i whara o ngā momo.

1. Myocyte mitotic wehenga ki te hanga i te nui e hiahiatia ana o kiko. Ko te ara māmā, me te tere tino noa ki te ora. Ko te kupu i reira ko te faaho'iraa mai i roto o tetahi okana i hanga e te uaua maeneene.
2. Myofibroblasts taea ki te whakaahua ke ki maheni pūtau uaua kikokiko, ki te tika. Ko reira atu uaua, me te taupetupetu mahi whakaora i ara o te kiko.

Innervation o uaua maeneene

kiko uaua maeneene mahi ona mahi takitahi o te hiahia hiahia ranei o te taata ora. Tenei he no te mea e waha ana tona karere te pūnaha io autonomic, me te te tukanga o te karere ganglia (tuaiwi).

Na he tauira o tenei tohu e taea te mahi ki te whakaiti i te whakapiki ake i te rahi o te puku, ate, kōateate ranei, totoro me te hukihuki o te tōngāmimi.

Ko te mahi o te kiko uaua maeneene

He aha te mea te auraa o tenei hanganga? He aha he maheni kiko uaua? Mahi whai reira:

• whakaiti wā roa-o te tinana taiepa;
• production ngaro;
• kaha ki te urupare ki whakaohooho, me te pānga o te excitability.
