Yosalala minofu minofu: mbali structural. The katundu wa minofu yosalala minofu

Animal zimakhala kuchita ntchito zofunika kwambiri mu thupi la zamoyo - mawonekedwe ndi mzere ziwalo zonse ndi kachitidwe. Zofunika makamaka pakati minofu awa ali ndicho, monga kufunika kwake mu mapangidwe lakunja ndi M'mimbamo lamkati la magawo structural wa patsogolo thupi. Nkhaniyi adzayang'ana pa zimene yosalala minofu minofu, makamaka kapangidwe ka katundu.

Zosiyanasiyana zimakhala izi

Chinyama chamoyo lili ndi mitundu minofu pang'ono:

• transversely wovulidwa;
• minofu yosalala minofu.

Onse a iwo ndi omwe zizindikiro zawo khalidwe la dongosolo, ntchito ndi akusonyeza katundu. Komanso, n'zosavuta kusiyanitsa pakati pawo. Ndipotu, ndi onse awo osiyana chitsanzo, amene anapanga kudzera kupanga gawo la zigawo mapuloteni maselo.

Striated bwino lagawidwa mitundu ikuluikulu iwiri:

• mafupa;
• mtima.

Dzina lokha amasonyeza madera chachikulu cha malo thupi. mbali zake ndi zofunika kwambiri, chifukwa ichi ndi musculature amapereka chidule cha mtima, kayendedwe ka miyendo ndi mbali zina zonse yoyamikira thupi. Komabe, yosalala minofu n'kofunika. M'magazini mwake, tiganizire moposera.

Ambiri, izo Tingaone okhawo amene ntchito bwino yolongosoka, anachita ndi yosalala ndi striated minofu minofu, kulola thupi lonse uziyenda bwino. Choncho, kudziwa zambiri kapena zochepa kwambiri a iwo n'zosatheka.

Yosalala minofu minofu: mbali structural

Kuweta zachilendo maonekedwe a dongosolo lino kugona mu kapangidwe ndi zikuchokera maselo ake - ena a minofu. Ngati wina aliyense, nsalu izi aumbike mwa gulu maselo ofanana mu dongosolo, katundu, kapangidwe ndi ntchito anachita. Nkhani zimene zimapezeka eg tinganene mu ndime zochepa.

1. Mukachipinda wazunguliridwa ndi tangle wandiweyani ulusi connective minofu, zomwe zikuwoneka ngati kapisozi a.
2. Lililonse limakhala structural zolimba kwa ena, malo intercellular ali pafupifupi kwina. Zimenezi zimathandiza nsalu lonse kunyamulidwa, kusasintha ndi olimba.
3. Mosiyana Anzawo striated, nyumba imeneyi mungakhale maselo a mawonekedwe wosiyana.

Izi, kumene, osati makhalidwe onse amene ali ndi minofu yosalala minofu. Features ya kapangidwe, monga kale chinanena mabodza myocytes okha, kugwira ntchito zawo ndi zikuchokera. Choncho, m'munsimu nkhani imene tikambirana mwatsatanetsatane.

myocytes yosalala minofu

Myocytes ndi wa mawonekedwe osiyana. Malinga ndi malo chiwalo makamaka, angakhale:

• chowulungika;
• elongated fusiform;
• anamaliza;
• Ndondomeko.

Komabe, mu Mulimonsemo, zikuchokera akukhudzidwira ndi ofanana ndi iwo. Iwo ali organelles monga:

• ofotokozedwa bwino ndipo likugwira mitochondria;
• Golgi zovuta;
• pachimake, elongated zambiri mu mawonekedwe;
• endoplasmic reticulum;
• lysosomes.

Mwachibadwa, ochiritsira ndi cytoplasm inclusions nawo pamsonkhanowo. N'zochititsa chidwi myocytes minofu yosalala kunja ataphimbidwa osati plasmolemma koma Kakhungu (woyambira). Imakhala ndi mwayi zina zolankhulirana ndi mzake.

zizindikiro zimenezi kupanga kukhudzana amaika minofu yosalala minofu. Lumikizanani malo dzina The Nexus. Kudzera mwa iwo, komanso kudzera pores, chimene malo awa akupezeka Kakhungu, ndi zimachitika imafalikira pakati pa maselo, kuwombola nkhani, mamolekyulu madzi ndi mankhwala ena.

Pali china chachilendo, amene ali ndi yosalala minofu minofu. Features ya kapangidwe ka myocytes ake kuti si onse amene ali ndi mitsempha mathero. Chifukwa chake ndi chofunika Nexus. Kaya khungu sakhala wopanda innervation, ndi patsogolo akhoza kudzera mwa dongosolo wotsatira nsalu.

Pali mitundu iwiri yaikulu ya maselo minofu.

1. Secretory. Ntchito yawo yaikulu ndi m'badwo ndipo kudzikundikira granules glycogen, kukhalabe kuchuluka polysomes mitochondria ndi mayunitsi ribosomal. Dzina dongosolo la zichokela ku zonsezo zili momwemo. contractile Izi akitini filaments ndi Ulimbo chingwe. Maselo amenewa nthawi zambiri isanafalikire pa periphery wa minofu.
2. Yosalala minofu ulusi. Ndi mawonekedwe a nyumba elongated spindle woboola pakati munali ndi phata chowulungika ankatembenukira pakati pa khola. Wina dzina leyomiotsity. Yodziwika ndi chakuti iwo ndi wokulirapo. Ena uterine thupi ta ku microns 500! Izi si chithunzi kwambiri maziko a maselo ena onse thupi yaitali koma dzira.

minofu yosalala ntchito ndi chakuti iwo lithe mankhwala zotsatirazi:

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

Olowa yolongosoka ntchito ndi anzake mitundu anasankha myocytes ndi bungwe dongosolo awo amapereka yosalala minofu minofu.

Magwero a minofu izi

Gwero mapangidwe mtundu uwu mu minofu thupi kuposa wina. pali zosankha zazikulu zitatu kwa anayambira. Ikufotokoza kusiyana lomwe lili dongosolo la minofu yosalala minofu.

1. Mesenchymal chiyambi. Ndi mbali yaikulu ya ulusi yosalala. Ndi chifukwa cha mezenhimi anapanga pafupifupi zimakhala zonse munzere mkati mwa ziwalo dzenje.
2. Epidermal chiyambi. Dzina lokha amalankhula za kutanthauzira malo - zopangitsa zonse khungu ndi ducts awo. Iwo anapanga ndi ulusi yosalala ndi zosinthika ngati ifika. Thukuta, malovu, mkaka, kuichotsa - zopangitsa izi secrete chinsinsi chifukwa mkwiyo myoepitheliocytes maselo - particles structural wa thupi ankaona.
3. Ubongo chiyambi. ulusi oterowo isanafalikire mu malo amodzi makamaka - Iris ndi imodzi mwa nembanemba diso. Kuchepetsa kapena kukulitsa wa mwana ndi innervated m'manja mwa maselo amenewa yosalala minofu.

Ngakhale osiyanasiyana, kapangidwe mkati ndi katundu wa ndense mitundu selo mu minofu pansi kulingalira kukhala pafupifupi ofanana.

The katundu waukulu minofu

Katundu yosalala minofu zizigwirizana anthu striated. Pochita zimenezi, iwo akugwirizana. Ali:

• madutsidwe;
• excitability;
• lability;
• contractility.

Pa nthawi yomweyo palinso mbali mwachilungamo yeniyeni. Ngati striated minofu chigoba mwamsanga kuotcha (ichi zikusonyezedwa bwino kugwedeza mu thupi la munthu), mukhoza kusalaza kwa nthawi yaitali boma wothinikizidwa. Komanso, ntchito zake sali pansi chifuniro ndi maganizo a munthu. Popeza amapereka mantha dongosolo autonomic.

A mbali yofunika kwambiri ndi luso m'mbuyo yaitali kutambasuka (kuchepetsa) ndi zosangalatsa chomwecho. Choncho, izi zachokera ntchito chikhodzodzo. Mu zochita za madzimadzi kwachilengedwenso (wokhutira) ndi wokhoza anatambasula kenako kuotcha. Makoma ake Ng'ona ndi minofu yosalala izo.

mapulotini selo

Myocytes ankaona minofu lili mankhwala osiyanasiyana. Komabe, zofunika kwambiri izi, amapereka ntchito za chidule ndi kutakasuka, ndi tinthu monga mapuloteni. A iwo apa:

• myosin filaments;
• akitini;
• nebulin;
• connectin;
• tropomyosin.

zigawo zikuluzikulu zimenezi zambiri imapezeka cytoplasm maselo olekanitsidwa mnzake popanda kupanga aggregates. Komabe, ziwalo zina nyama zooneka mitolo kapena chingwe, wotchedwa myofibrils.

Location mu minofu wa matabwa zimenezi makamaka kotenga. Onse myosin filaments ndi akitini. Chifukwa ndi maukonde imene malekezero imalukanira ena m'mbali ndi tinthu zina zomanga thupi. Nkofunika kwa mofulumira ndi choyenera kuchepetsa nsalu lonse.

Nkosafuna kuchepetsa chiri motere: ngati mbali ya chilengedwe mkati mwa selo ndi vesicles pinocytic, amene kwenikweni muli kashiamu ayoni. Pamene mitsempha mopupuluma akadzafika, akulankhula za kufunika kuchepetsa kuwira ikuyandikira ndi fibril. Chifukwa, kashiamu ion zosasangalatsa akitini ndipo mapanganowo chozama pakati pa filaments wa myosin. Apa tikutengegeredwa ku tingoti nembanemba plasma ndi chifukwa cha myocyte ndi yafupika.

Yosalala minofu minofu: kujambula

Ngati ife kulankhula za minofu striated, izo mosavuta anazindikira mwa striations. Koma pano monga tiganizire dongosolo, ndiye izi sizichitika. Chifukwa minofu yosalala chitsanzo n'zosiyana kwambiri kuposa inzake lapamtima? Ichi ndi chifukwa kukhalapo ndi malo zigawo mapuloteni mu myocytes lapansi. Monga mbali ya yosalala myofibrils minofu yarns zosiyanasiyana zachilengedwe m'madera wachisokonezo, popanda atathana analamula boma.

N'chifukwa chake chitsanzo nsalu si zilipo. Mu striated akitini filament successively m'malo mwa mtanda myosin. Chifukwa ndi chithunzi - striation, chifukwa chimene nsalu afika dzina lake.

Mu maso pa, nsalu yosalala zikuwoneka yosalala kwambiri ndi streamlined, chifukwa mwamphamvu pafupi wina ndi mnzake longitudinally anakonza myocytes elongated.

Okhudza malo malo mu thupi

Yosalala minofu minofu ndipamene chiwerengero mwachilungamo lalikulu ziwalo zofunika mkati mwa thupi nyama. Kotero, iye anapanga:

• matumbo;
• kumaliseche;
• mitundu yonse Mitsempha;
• khansara;
• ziwalo excretory a dongosolo;
• kupuma thirakiti;
• gawo la chowunikira zithunzi;
• ziwalo dongosolo m'mimba.

Nchachidziwikire, kutanthauzira minofu pansi kulingalira ndi osiyanasiyana kwambiri ndi zofunika. Komanso tisaiwale kuti mitundu ina mu minofu makamaka amene Matupi imvera automaticity anira.

Njira kuchira

Yosalala minofu minofu ndipamene nyumba mwachilungamo zofunika kuti angathe buluzi. Choncho, amakhala ndi njira ziwiri zazikulu mu kuvulala zamitundu yosiyanasiyana.

1. Myocyte mitotic magawano kupanga ndalama Napempha kwa minofu. Ambiri kumodzi ndi mwachangu njira kuchira. Choncho pali kubwezeretsa mkati mwa chiwalo chilichonse popangidwa ndi minofu yosalala.
2. Myofibroblasts kusintha mu ena a minofu yosalala minofu ngati n'koyenera. Ndi kovuta ndi infrequent njira kusinthika kwa minofu.

Innervation minofu yosalala

Yosalala minofu minofu amagwira ntchito yake popanda chikhumbo kapena kusafuna wa munthu wamoyo. Ichi ndi chifukwa mitsempha yake amanyamula dongosolo autonomic mantha, komanso ndondomeko ya ganglia mitsempha (msana).

Ndipo chitsanzo cha chitsimikizo angathe kutumikira kuchepetsa kapena kuwonjezera kukula kwa m'mimba, chiwindi, ndulu motsatizana ndi chidule cha chikhodzodzo.

Ntchito ya minofu yosalala minofu

Kodi tanthauzo la nyumba imeneyi ndi chiyani? N'chifukwa chiyani yosalala minofu minofu? Liziyenda ndizoonekeratu:

• kuchepetsa yaitali matupi pakhoma;
• zinsinsi kupanga;
• luso kulabadira zimene zikuchitika ndi zotsatira za excitability.
