Mesebetsi ya dinama tse nyenyane tse mesifa le mefuta sebopeho

'Mele oa liphoofolo tsohle, ho akarelletsa le batho, e entsoe ka mefuta e mene ea lisele: epithelial, ke tšohile, connective le mesifa. Ka bobeli li tla tšohloa sehloohong sena.

Mefuta e fapaneng ya dinama tse nyenyane tse mesifa

Ke tsa mefuta e meraro:

• striated;
• boreleli;
• pelo.

Mesebetsi ya mesifa dinama tse nyenyane tse mefuta e fapaneng tsela e sa tšoaneng. Le sebopeho haholo.

ke moo mesifa dinama tse nyenyane tse ka 'mele oa motho?

Muscle dinama tse nyenyane tse mefuta e fapaneng lula sebakeng se fapaneng ka 'mele oa batho le liphoofolo. Ka tsela eo, ka lebaka la ho mesifa pelo, e le lebitso la ka fana ka maikutlo a, e hahiloeng pelo.

Ho tswa ho striated mesifa ya marapo thehoa mesifa dinama tse nyenyane tse.

mesifa Smooth mohala hare cavity, eo lokela ho tsa fokotswa. Ena, ka mohlala, mala, senya, popelo, mala, joalo-joalo

mesifa sebōpeho sa mefuta e fapaneng fapana. Ka puo ea hae ka ho qaqileng haholoanyane e tlang.

Joang mesifa dinama tse nyenyane tse?

Ho na le ka lisele tse kholo-boholo bo lekaneng - lisele tse mesifa. Ba ile ba boela ba boetse o bitsoa le litlheferetsi. Muscle lisele tse nang le selotlolo mantlha 'me ba bangata mitochondria - organelles le boikarabelo ba ho fana ka tlhahiso matla.

Ho feta moo, sebopeho sa mesifa ea lisele batho le liphoofolo ho akarelletsa ho ba teng ha e nyenyane ea intercellular ntho e nang le collagen, eo fana ka elasticity mesifa.

A re ke re sheba ka sebopeho le mosebetsi oa mesifa dinama tse nyenyane tse mefuta e fapaneng ka thoko.

Sebopeho le karolo e phethoang ke mesifa le boreleli dinama tse nyenyane tse

lesela lena e laoloa ke tsamaiso ea methapo autonomic. Ka lebaka leo, motho a ke ke fokotsa mesifa natla hahoa tloha lesela boreleli.

Ho Ho thehoa ho tswa mesenchyme ena. Ho e mosa ea embryonic connective dinama tse nyenyane tse.

Fokotsa dinama tse nyenyane tse ena ke haholo ka tlaase ho moo a sebetsang a 'me ka potlako ho feta striated.

Boreleli lesela e hahoa ya sebopeho myocytes fusiform le lipheletsong nchocho. Bolelele ea lisele tsena e ka ba ho tloha micrometers 100 ho tse 500, le botenya - tse ka bang 10 micrometers. Lisele tsa dinama tse nyenyane tse le a mononuclear. khubu ea teng e bohareng ba myocyte ena. Ho feta moo, hantle-ntshetswa pele organelles kang mitochondria le EPS agranular. Hape le mesifa boreleli lisele tse dinama tse nyenyane tse ke palo e khōlō ea inclusions glycogen, e etsa hore mehloli ea limatlafatsi.

Karolo eo e fana ka phokotso ea mesifa dinama tse nyenyane tse mefuta ea, ba myofilaments. Ba ka hahoa liprotheine tse peli contractile actin le myosin. Bophara myofilaments hore bopilwe myosin, ke 17 nanometers, 'me ba tse hahoa actin - 7 nanometers. Ho boetse ho na myofilaments lipakeng bao bophara e 10 nanometers. Dikamano longitudinal myofibrils.

Sebōpeho sa mofuta ona wa dinama tse nyenyane tse mesifa e boetse e akarelletsa kantle ho sele popeho ya collagen, eo e fana ka puisano pakeng tsa myocytes motho.

Mesebetsi ya mesifa dinama tse nyenyane tse ea mofuta ona:

• Sphincter. Ke ea lisele tse boreleli mesifa lokisetsa ka chitja laolang diteng tsa le phetoho 'mele ho e' ngoe kapa ho tloha karolong e 'ngoe ea' mele ea ho e 'ngoe.
• Sebakeng seo. Ho itšetlehile ka 'nete ea hore mesifa e boreleli thusa' mele excrete lihlahisoa lesupi, hammoho le ho kenya letsoho ha tshebetso ya ho pelehi.
• Bōpa e lumen vascular.
• Sebopeho sa sethusathuto le ligamentous. Thanks ho eena, litho tsa ka hare tse ngata, tse kang liphio, ba tšoareloa sebakeng.

Joale a re sheba sebōpeho sa dinama tse nyenyane tse mesifa.

Striated

E laoloa ke sa tsamaiso ea methapo somatic. Ka lebaka leo, monna a ka natla laola mofuta ona wa mesifa. Ho tswa ho striated ya marapo mesifa dinama tse nyenyane tse thehoa.

dinama tse nyenyane tse ena e na le likhoele. Tsena ke lisele tse ba le plurality ea cores ho lokeng haufi le lera lero la mali. Ho phaella moo, ba na le e ngata ea inclusions glycogen. Hantle-ntshetswa pele organelles kang mitochondria. Ba haufi le lisele tsa contractile ea thepa ea motheo. organelles tse ling tsohle tse haufi le nuclei le hampe ntshetswa pele.

Mehaho e ka eo sefapano metsero lesela e fokotsehile, ke myofibrils. bophara ba bona e pakeng tsa e 'ngoe le e' meli micrometers. Myofibrils lula ho fetisisa ea sele 'me ba tsamaisa ka ho setsi sa lona. Dikamano longitudinal myofibrils. Ba li na le leseli 'me disks lefifi, fapanyetsana, e baka sefapano "metsero" lesela.

Mesebetsi ya mesifa dinama tse nyenyane tse ea mofuta ona:

• Fana ka 'mele ho fallela ka sebaka.
• Ke eena ea ikarabellang bakeng sa motsamao oa likarolo 'mele oa amanang le ho e mong le e tse ling.
• le bokhoni ba ho boloka mele ea 'mele ea.
• Amehang ka molao oa tsamaiso ea mocheso: ya fokotswa mesifa mafolofolo, a phahameng mocheso. Ha freezing mesifa striated a ka qala ho tšoaroa ke involuntarily. Sena se hlalosa hore na ho thothomela ea 'mele.
• Sebeletsa mosebetsi e sireletsang. Sena ke 'nete haholo-holo ha mesifa mpeng, eo ho sireletsa litho tsa ka hare tse ngata ka hare ho tloha senya.
• Ho sebetsa e le depo ea metsi le matsoai.

Cardiac mesifa dinama tse nyenyane tse

lesela Sena ke ka tsela e tšoanang bobeli ka striated, 'me e be tse boreleli. Hammoho le boreleli, e laoloa ke tsamaiso ea methapo ea kutlo autonomic. Leha ho le joalo, ntseng le nyenyefala e le ka mafolofolo e le striated.

Ho e na le lisele tse bitsoang cardiomyocytes.

Mesebetsi ya mesifa dinama tse nyenyane tse ea mofuta ona:

• Ke e 'ngoe feela: e leng ho etsa bonnete ba motsamao oa mali ka' mele.
