Ntchito ya minofu yosalala minofu. Yosalala minofu minofu: kapangidwe

Nsalu - ya kapangidwe zofanana khungu, amene kugawana zinthu wamba. Pafupifupi zamoyo zonse multicellular ndi lopangidwa osiyanasiyana zimakhala.

Gawo

Nyama ndi anthu alipo mu thupi zotsatirazi mitundu minofu:

• zaminyewa;
• wamanjenje;
• mphambano;
• minofu.

anthu amenewa anali amaphatikiza mitundu angapo. Choncho, minofu connective ndi mafuta, chichereŵechereŵe, fupa. Mulinso magazi ndi lymph. Zaminyewa minofu pali umodzi-wosanjikiza ndi Mipikisano wosanjikiza, malingana ndi kapangidwe ka maselo akhoza olekanitsidwa mosabisa, kiyubiki, cylindrical epithelium, ndi zina zotero. D. mantha mtundu umodzi wokha. mtundu A minofu minofu tikambirana mwatsatanetsatane m'nkhani ino.

Mitundu ya minofu minofu

Mu thupi la nyama zonse secrete mitundu ake atatu:

• yosalala minofu;
• striated minofu;
• mtima minofu minofu.

Ntchito ya minofu yosalala minofu ndi osiyana ndi anthu a striated ndi mtima, kotero iye ndi dongosolo. Tiyeni tione mwatsatanetsatane dongosolo la mtundu uliwonse wa minofu.

General maonekedwe a minofu minofu

Popeza kuti onse atatu ali m'modzi, ali ndi zambiri zofanana.

Minofu maselo otchedwa myocytes, kapena ulusi. Malinga zosiyanasiyana zimakhala, akhale ndi dongosolo losiyana.

Minofu minofu, zithunzi zimene Tingaone pansipa, ali pafupifupi palibe mankhwala intercellular.

China wamba mitundu yonse ya minofu ndi kuti iwo angathe kuchepetsedwa Komabe, mitundu yosiyanasiyana, ndondomeko izi zimachitika payekha.

Features myocytes

Ena a minofu yosalala minofu, ngati striated ndi mtima ndi mawonekedwe elongated. Komanso ali ndi organelles wakupambulika dzinache myofibrils, kapena myofilaments. Iwo ali mapuloteni contractile (akitini, myosin). Iwo pofuna kayendedwe ka minofu. A chofunika minofu kugwira ntchito, popanda kukhalapo kwa mapulotini contractile, ndi pamaso pa ayoni kashiamu mu maselo. Choncho, osakwanira kapena kumwetsa mowa zakudya ndi okhutira mkulu wa amafotokozera zimenezi zikhoza wonongeka minofu - onse yosalala ndi striated.

Komanso, maselo pano wina mapuloteni yeniyeni - myoglobin. M'pofunika kulankhula ndi mpweya ndi kusunga.

Ponena organelles, popanda pamaso pa myofibrillar wapadera kwa minofu zili minofu ndi ambiri mitochondria selo - dvumembrannyh organelles udindo kupuma ma. Zimenezi n'zosadabwitsa, ngati minofu CHIKWANGWANI kuchepetsa wambirimbiri mphamvu ayenera kupangidwa pa kupuma mu mitochondria.

Mu ena myocytes imapezekanso mwa pachimake kuposa wina. Izi ndi khalidwe la ena a minofu striated kuti anyamula pafupi twente mitima, ndipo nthawizina chithunzi lino mpaka zana. Ichi ndi chifukwa chakuti CHIKWANGWANI minofu striated aumbike maselo angapo, ndiye amaphatikizidwa mu chimodzi.

Kapangidwe ka minofu striated

mtundu wa nsalu wotchedwa minofu chigoba. Yapamwamba a mtundu umenewu kutalika minofu, anasonkhana mu mitolo. Maselo amenewa akhoza kukhala masentimita angapo yaitali (10-12). Iwo ali mtima ambiri, mitochondria ndi myofibrils. Mfundo zikuluzikulu structural unit wa aliyense myofibril minofu striated - sarcomere. Amakhala ndi mapuloteni contractile.

Mbali yaikulu ya minofu izi kuti akhoza lizilamuliridwa mozindikira, mosiyana ndi yosalala ndi mtima.

Ulusi wa nsalu amagwira mafupa kudzera tendons. N'chifukwa chake zimenezi zimatchedwa minofu chigoba ndi.

Kapangidwe ka minofu yosalala minofu

Yosalala minofu kumalumikiza ena ziwalo mkati monga matumbo, chiberekero, chikhodzodzo, ndi mitsempha ya magazi. Komanso, iwo apanga sphincters ndi Mitsemphayi.

Yosalala minofu CHIKWANGWANI si bola striated lapansi. Koma wochindikala ndi wamkulu kuposa pa nkhani ya minofu chigoba. Ena a minofu yosalala minofu ndi veretonopodobnoy mawonekedwe osati filamentary monga myocytes striated.

Nyumba kuti obesechivayut minofu yosalala chidule, wotchedwa protofibrils. Mosiyana myofibrils, iwo ndi dongosolo chosavuta. Koma nkhani imene iwo ali omangidwa - yemweyo mapuloteni contractile akitini ndi myosin.

Mitochondria mu myocytes minofu yosalala ndi zosakwana ku maselo a striated ndi mtima. Komanso, iwo ali yekha phata limodzi.

Features a minofu mtima

Akatswiri ena tanthauzo monga subspecies wa striated minofu minofu. CHIKWANGWANI wawo uli kwambiri mofanana. mtima maselo - cardiomyocytes - muli mitima angapo, ambiri myofibrils ndi mitochondria. nsalu iyi, komanso minofu chigoba angathe kuchepetsedwa zambiri mofulumira ndi wamphamvu kuposa minofu yosalala.

Komabe, mbali yaikulu kusiyanitsa minofu mtima striated, ndi kuti sangathe ankalamulira bwino. Kuchepetsa yekha zimachitika basi, monga mu nkhani ya minofu yosalala.

Monga mbali ya minofu mtima, kuwonjezera maselo lililonse imapezekanso secretory cardiomyocytes. Iwo mulibe myofibrils ndipo ali yafupika. Maselo amenewa otvesayut atriopeptina kwa kupanga timadzi, amene n'kofunika kuti lamulo la magazi ndi ulamuliro buku magazi.

Mchitidwe wa minofu striated

ntchito yaikulu - kusuntha thupi m'malere. Ndi kayendedwe ka ziwalo wachibale wina ndi mzake.

Mwa ntchito zina striated minofu akhoza taonera kukhalabe kugwedeza zofikira madzi ndi mchere. Komanso, adzagwiritsidwa ntchito zoteteza, makamaka pankhani ya minofu m'mimba popewa kuwonongeka mawotchi ziwalo mkati.

ntchito akhoza kukhala m'gulu la lamulo la kutentha kwa musculature striated, monga amapezeka zamoyo wa kutentha ndithu ndi yogwira akulu chidule. Ndicho chifukwa pamene peremerzanii minofu unayamba kunjenjemera involuntarily.

Ntchito ya minofu yosalala minofu

Musculature wa mtundu uwu amachita achoke ntchito. Iwo kwagona kuti minofu yosalala intestine ndi kulikankhira chopondapo kwa malo Kupha kwawo kwa thupi. Komanso, ntchito imeneyi akuwonekera pa kubadwa, pamene minofu yosalala chiberekero kulikankhira zipatso za thupi.

Ntchito ya minofu yosalala minofu si zochepa. Komanso yofunika kwambiri sphincter awo. Nsalu ya mtundu uwu anapanga ndi wapadera zozungulira minofu kuti akhoza occlude ndi lotseguka. Sphincters alipo kapepala kakuti mkodzo, m'matumbo, pakati pa m'mimba ndi kum'mero, chikhodzodzo ndulu, mu mwana wa.

Ntchito ina yofunika minofu yosalala - mapangidwe zida za ligamentous. M'pofunika kukhala malo olondola a ziwalo mkati. Ndi kutsitsa kamvekedwe ka minofu imeneyi prolapse ziwalo zina angayambe.

Pa ntchito iyi yosalala minofu mapeto.

Cholinga cha minofu mtima

Apa, mfundo, palibe wapadera kunena. Waukulu ndi kokha ntchito ya minofu imeneyi - kupereka magazi m'thupi.

Kutsiliza: kusiyanitsa mitundu itatu ya minofu minofu

Pakuti Kuwulura nkhani tilalikira tebulo:

Ndi makhalidwe zonse zoyambirira za striated, yosalala ndi mtima minofu minofu. Tsopano muli bwino ntchito zawo, kapangidwe, ndi kusiyana chachikulu ndi zofanana.
