Vamwe uterine muviri nezvimedu kusvika 500 microns! Uyu chaizvo zvinonyatsooneka ndeuke pakanyorwa dzimwe masero ose mumuviri refu kunze zai.

kwakanaka tsandanyama basa iri uyewo iri chokwadi kuti synthesize zvinotevera yeimwe:

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

Joint kwakarongeka basa uye kudyidzana mhando akasarudzwa myocytes uye sangano ravo marongerwo inopa mvere tsandanyama tishu.

Mabviro mhasuro ichi

Source paumbwe ichi mhando mumuviri tsandanyama pane mumwe. pane chikuru zvitatu nokuda mavambo. Izvi rinotsanangura kusiyana, iro rine maumbirwo mvere tsandanyama tishu.

1. Mesenchymal mavambo. Zviri guru chikamu kumeso fibers. Imhaka mezenhimi vakaumba zvinenge munyama zvose kuti anomira mukati negomba zvomukati.
2. Epidermal mavambo. The zita pacharo rinotaura pamusoro localization nzvimbo - zvose ganda mumasero vavo ducts. Vari inoumbwa kumeso fibers vane musiyano wezvinyorwa kwakadaro wasvika. Ziya, nemate, mukaka, misodzi - mumasero izvi secrete zvakavanzika nokuda kutsamwa myoepitheliocytes masero - STRUCTURAL nezvimedu of nezvomuviri.
3. Neural mavambo. fibers vakadaro vemunyika mune imwe nzvimbo yakati - Iris mumwe ziso membranes. Zvinoderedza kana akawedzera mboni iri innervated uye kudzora kumeso tsandanyama masero aya.

Pasinei zvaimbenge, dzomunyika marongerwo uye zvivako zvose akatakura sero mhando iri rinenge pasi kukurukurwa kuramba ndezvomuzana chete.

The chikuru ehupfumi ari tishu

Properties kumeso tsandanyama anoenderana avo nokuda striated. In ichi vanobatana. Ivo:

• conductivity;
• excitability;
• lability;
• contractility.

Panguva iyoyo kunewo zvakanaka chaizvo chinhu. Kana striated skeletal tsandanyama anogona kukurumidza shure (izvi zvakanaka nezvakaitwa tremor mumuviri womunhu), unogona chechetere kwenguva refu yaiitirwa compressed mamiriro. Uyezve, mabasa ayo havasi pasi kuda uye nepfungwa murume. Sezvo anopa autonomic tsinga.

A chinokosha zvikuru chinhu kukwanisa kuderedza chiwedzerwa kwenguva refu (rutapudzo) uye zvakafanana kuzvivaraidza. Saka, ichi kunobva pabasa dundira. Under Zvakaitwa zvipenyu mvura (ayo kugutsikana) zviri kukwanisa ruchatambanudzirwa uye ipapo shure. masvingo aro mudungwe pamwe mvere tsandanyama nayo.

sero mapuroteni

Myocytes vaiona zvinyama rine yeimwe siyana dzakawanda. Zvisinei, chinonyanya kukosha izvi, anopa mashandiro anoita marwadzo uye kutandara, inongova mapuroteni mamorekuru. Vavo vakawana pano:

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

zvinoriumba aya kazhinji riri cytoplasm masero kure mumwe pasina nokuumba aggregates. Zvisinei, mune zvimwe nhengo kwemhuka zvakaumbwa mwanda kana tambo, inonzi myofibrils.

Location ari zvinyama pamusoro matanda aya kunyanya longitudinal. Vose myosin filaments uye actin. Zvinoguma samambure umo kumigumo vari rakarukwa zvimwe kumicheto nevamwe mapuroteni mamorekuru. Zvinokosha kuti kufambira uye zvakakodzera rutapudzo yacho rejira yose.

Hazvibetseri rutapudzo iri sezvinotevera: sechikamu dzomunyika kwezvakatipoteredza muchitokisi vane pinocytic vesicles, izvo hazvo rine karusiyamu ions. Kana tsinga zvairatidza wasvika, kutaura nezvokukosha kuderedza sefuro ichi anosvika fibril. Somugumisiro, mashoko karusiyamu Ion kunetsa actin uye kufambira mberi zvakadzika pakati filaments ose myosin. Izvi zvinotungamirira kupoteredza yeplasma Kamudzira uye somugumisiro wacho myocyte ipfupi.

Smooth tsandanyama tishu: richiswedera

Kana isu kutaura pamusoro striated rinenge riri nyore anozivikanwa striations. Asi pano sezvo tiri kufunga mamiriro, ipapo ichi hazviitiki. Sei kwakanaka tsandanyama muenzaniso zvakasiyana pane yake yepamwoyo muvakidzani? Izvi imhaka pamberi uye nzvimbo yacho puroteni zvinoumba ari myocytes. Senzira kumeso tsandanyama myofibrils pemavara akasiyana vemunyika hunhu runobva, pasina wakaiswa akarayira mamiriro.

Ndokusaka Mucheka muenzaniso hadzisi kuwanika. In striated actin filament successively chikatsiviwa muchinjikwa myosin. Zvinoguma mufananidzo - striation, nokuda izvo Mucheka inowana zita rayo.

Pasi maikorosikopu, jira kumeso anotarisa kumeso chaizvo uye streamlined, nemhaka zvakasimba yakabatana mumwe longitudinally akaronga elongated myocytes.
