Smooth mesifa dinama tse nyenyane tse: ha se ikamahantse le thato ea monna

Joalokaha u tseba, lisele tsohle mesifa na makgetheng tloaelehileng. Empa esita le karolelano ya kalafi seithuti hore e ho le bonolo ho khetholla le mekhoa ea mefuta e fapaneng ea lisele. Smooth mesifa dinama tse nyenyane tse nang le ho se tšoane bath. 'Me haeba u na le bonyane fokolang haholo tsebo, u ke ke ua ferekanya striated le boreleli mesifa. Ho e bonolo ka ho lekaneng. A sehloohong sena a re tla bua ka seo ke le boreleli mesifa dinama tse nyenyane tse, empa hape le ka thepa ea eona le sebopeho.

The tšobotsi sehlooho tseo distinguishes mofuta ona wa dinama tse nyenyane tse ho tswa ho mesifa dinama tse nyenyane tse, e leng e khannoang ke kelo-hloko batho (leha e le efe), - lebaka la ho hloka ea sefapano-striations. Ka seleng e 'ngoe ho na le ke e' ngoe feela ea se nang molekane ea mantlha, haufi le bohareng ba eona (mokhoeng o tšoanang ke mesifa pelo). Ke lōna bao 'me u tla bona tlas'a ya microscope slide.

Karolo e khōlō ea boreleli mesifa dinama tse nyenyane tse e teng marakong a makala sekoti ea litsamaiso fapaneng, hammoho le karolo ea marako a sejana. Ha lisele ena e teng ka lerako la 'mele, hangata ho bopa le dikarolo tse peli. Inner - lesale le ka ntle - longitudinal. Leha ho le joalo, likarolong tse ling tsa tsamaiso ea tse sa tšoaneng tsa puso ea ena e hataketse, le likhoele li lokisetsa spirally, ho etsa mohlala, ka methapo kgolo. Feela ka boemo ba arterioles mesifa dinama tse nyenyane tse batho ba lokisetsa ka likhoele tse chitja.

le dikarolo ba ne ba le boreleli mofuta oa dinama tse nyenyane tse arotsoe ka dingata tsa likhoele, e mong le e ea eona e pota-potiloe ke dinama tse nyenyane tse connective, eo ka eona liseleng mesifa ke a loketse bakeng sa ka methapo ea kutlo le vials mali. The tufts ba lohellana le mong ho e mong, 'me ka hona e bopa e mosa ea kopantswe marangrang tsa likhoele mesifa, e phethe mosebetsi oa bona hammoho.

Smooth mesifa dinama tse nyenyane tse hammoho le mesifa pelo, ke boikarabelo ba tsamaiso ea methapo autonomic, 'me ka hona tšebetso ea oona ha ho ya taolo elang hloko. lesela ena ke khona ho nako e telele ka ho boemong ba ho fokotsa ho a leeme (tšehetsa molumo). Ka lebaka leo, mehaho e tubular khona ho nako e telele ho ba le rengwa itseng. Sena ke sa bohlokoa bakeng sa ka tekanyo e itseng ka khatello ea batlang e le kamehla mali.

Haeba molumo e ntlafatsoa, ho lumen ka narrowed. Ka linako tse ling ho ke ke pathological. Ka mohlala, ha motho a le bothata ba ho le asma e, le boreleli mesifa molumo nyenyane ka ho fetisisa bronchial methapo fetoha ka tsela e feteletseng, 'me moea ke ke potoloha hantle. Tsela e tšoanang, ho ea ka litlaleho tse ling, ke ka lebaka la sebōpeho sa kgatelelo ya madi ka batho.

Smooth mesifa dinama tse nyenyane tse e boetse ke matla a ho laola palo ea elastin ka methapo ea mali. Marakong a pampitšana gastrointestinal, ho ureters le fallopian methapo boreleli konteraka mesifa rhythmically, eaba ba etsa seo ho thoeng ke maqhubu peristaltic eo matha ka methapo le sutumelletsa bona ka litaba tse ka hare tsela e nepahetseng.

Ha re bapisa striated le boreleli lisele tse mesifa, ho ka ho hlokomela hore le boreleli fokolloa tse ling tse ngata, butle-butle. Mokhelo - boreleli thaka dibopeho hore hang-hang ba arabela joang leseli.

E le o tsejoa, ka mesifa dinama tse nyenyane tse e na le liprotheine tse actin le myosin. Ho ile ha fumanoa hore actin liseleng boreleli mesifa ho feta ka striated. Hape, lithuto tsa sebelisa eketsehile haholo microscopes senola hore reticulum sarcoplasmic ka lisele tse boreleli mesifa e ka tlase tsoetseng pele ho feta ka striated ena.

Joalokaha re bone ka holimo, ho na le mefuta e 'meli ea mofuta o dinama tse nyenyane tse ka eona. Lisele tsa pele, e leng e entsoe ka 'mele, ke khona ho sekama butle haholo. mofuta ona o bitsoa visceral. Empa boreleli mesifa dinama tse nyenyane tse ka sebopeho sa sphincter tsa thaka ea, ke khona ho fokotswa ka potlako, e mesifa dinama tse nyenyane tse o bitsoa le motho ea faeba innervation. Ka lebitso la bobeli, moo e mong le e faeba na methapo ea kutlo lona. Mofuta oa pele oa ditjeo 'mele "theko e tlaase" - tshebetso tšohile ho' nile ha e ngata faeba.

More ka mesifa boreleli dinama tse nyenyane tse ka fumanoa libuka tsa sobotta. Empa ho fumana boitsebiso bo bao e seng baruti sehloohong sena e lokela ho ba lekana.
