Mashandiro anoita mvere tsandanyama tishu. Smooth tsandanyama tishu: mamiriro

Jira - kuva yakafanana muchitokisi mamiriro, izvo kugoverana nevakawanda zvinhu. Zvinenge zvose zvinenge zvipuka zvine masero akawanda akaumbwa rakasiyana-siyana munyama.

kupatsanura

In mhuka uye vanhu mumuviri inotevera tishu mhando:

• epithelial;
• huta;
• Junction;
• tsandanyama.

Mapoka aya kubatanidzwa kuti mhando dzakawanda. Nokudaro, connective zvinyama wakakora, shwashwa, mapfupa. Kunosanganisirawo ropa uye node. Epithelial zvinyama pane chimwe rukoko uye multi-layer zvichienderana nemamiriro masero zvinogona dzoga sandara, cubic, cylindrical epithelium, uye zvichingodaro. D. huta ndiyo chete mhando imwe. A mhando tsandanyama rinenge ichakurukurwa muudzame munyaya ino.

Mhando tsandanyama tishu

Mumuviri mhuka dzose secrete dzaro mhando nhatu:

• wakatsetseka mhasuro;
• striated mhasuro;
• cardiac tsandanyama tishu.

Mashandiro anoita kumeso tsandanyama rinenge yakasiyana vaya striated uye mwoyo, saka zvose iye nechivako. Ngatimboongororai zvakadzama sechivako neimwe mhando tsandanyama.

General unhu tsandanyama tishu

Sezvo vose vatatu kwakadaro, vane zvakawanda zvakafanana.

Muscle masero anonzi myocytes, kana fibers. Zvichienderana-siyana munyama, ivo vangava akasiyana yakarongeka.

Muscle rinenge mapikicha izvo zvinogona kuonekwa pazasi, ane anenge asina intercellular fuma.

Chimwe zvakafanana kuchiitwa marudzi ose tsandanyama ndechokuti zvingaderedzwa Zvisinei, zvakasiyana mhando, izvi kunoitika nomumwe.

Features myocytes

Masero wakatsetseka tsandanyama rinenge rakaita striated uye cardiac vane elongated chimiro. Mukuwedzera, vane organelles anokosha rinonzi myofibrils, kana myofilaments. Inosanganisira contractile mapuroteni (actin, myosin). Ndivo zvakakodzera kuitira kufamba netsandanyama. Chinodiwa tsandanyama kushanda, kunze pamberi contractile mapuroteni, ndiyewo kuvapo calcium ions ari mumasero. Naizvozvo, kushomeka kana kunyanya kunwa zvekudya rurefu zviri maatomu akafanana izvi zvingakonzera atadze kushanda zvakanaka tsandanyama - zvose kumeso uye striated.

Uyezve, masero varipo chete dzakananga mapuroteni - myoglobin. Zvakakodzera kutaura okisijeni uye kuchengeta nayo.

Achitaura organelles, kunze pamberi myofibrillar chaiwo tsandanyama rinenge tigutsikane chiri vazhinji mitochondria muchitokisi - dvumembrannyh organelles anokonzera cellular afemeruke. Izvi hazvishamisi, sezvo tsandanyama faibha kuderedza yakawanda simba anofanira kubudiswa panguva afemeruke mu mitochondria.

Mune dzimwe myocytes vari kuuyawo kupfuura imwe core. Izvi manyorerwo striated tsandanyama masero kuti ingasanganisira cores vanenge makumi maviri, uye dzimwe nguva nhamba iyi kunosvika kumusoro zana. Izvi imhaka ndechokuti zvachose striated tsandanyama achiumbwa masero akawanda, ipapo aibatanidza imwe.

Sechivako striated mhasuro

Izvi mhando rejira anonzi skeletal tsandanyama. Fibers kwaiita tsandanyama urefu, yakaunganidzwa mwanda. Masero aya ave dzakawanda masendimita refu (kusvika 10-12). Dzine vakawanda nuclei, mitochondria uye myofibrils. The inokosha STRUCTURAL chairema nerimwe myofibril ose striated zvinyama - sarcomere. It rine contractile mapuroteni.

The chikuru chinoratidza tsandanyama ichi ndechokuti zvinogona kudzorwa nokungwaririra, mukusiyana kune kumeso uye cardiac.

The fibers of Mucheka vari kurerekera mapfupa Via nemarunda. Ndokusaka izvi dzinonzi skeletal tsandanyama uye.

Maumbirwo wakatsetseka tsandanyama tishu

Smooth tsandanyama lining dzimwe zvomukati dzakadai muura, dumbu, dundira, nemidziyo ropa. Mukuwedzera, vanoumba sphincters nemarunda.

Smooth tsandanyama faibha hakusi sokuvapo striated. Asi Ukobvu mukuru kuna skeletal tsandanyama. Masero kumeso tsandanyama rinenge vane veretonopodobnoy chimiro pane filamentary sezvo striated myocytes.

Zvivako kuti obesechivayut wakatsetseka tsandanyama marwadzo, akadana protofibrils. Kusiyana myofibrils, vane nyore yakarongeka. Asi zvinhu izvo yakavakwa uko - zvakafanana contractile mapuroteni actin uye myosin.

Mitochondria mu myocytes kumeso tsandanyama zvakare muduku kupfuura mumasero striated uye cardiac. Mukuwedzera, ivo maingova neerekitironi rimwe.

Zvakakurukurwa mwoyo mhasuro

Vamwe vatsvakurudzi vanokurondedzera somunhu subspecies pamusoro striated tsandanyama tishu. faibha yavo iri yakawanda zvakafanana. mwoyo masero - cardiomyocytes - dzinewo cores kakawanda, vakawanda myofibrils uye mitochondria. jira ichi, uyewo skeletal tsandanyama, anogona kuderedzwa zvikuru nokukurumidza uye akasimba kupfuura kumeso tsandanyama.

Zvisinei, chikuru chepfungwa kusiyanisa pomwoyo kubva striated, ndiko kuti rukoniwe kudzorwa nokungwaririra. Kuderedza chete zvinoitika rwoga, sezvo zvakaita kumeso netsandanyama.

Sezvo chikamu mwoyo rinenge kuwedzera mumufananidzo masero vari kuuyawo secretory cardiomyocytes. Havazivi dzine myofibrils uye haana kuderedzwa. Masero aya otvesayut atriopeptina kuti kugadzirwa kemikari, izvo zvinokosha kuti mutemo BP uye ropa vhoriyamu kuzvidzora.

Basa striated mhasuro

Chavainyanya basa - kufamba muviri muchadenga. Ndizvo sangano wemigove dzomuviri hama kune mumwe.

Zvimwewo mabasa striated tsandanyama zvinogona kucherechedzwa kuramba postures chakazara nemvura uye munyu. Mukuwedzera, ivo vanoshumira unodzivirira basa, kunyanya panyaya abdominal tsandanyama kudzivisa zvokuimba kukuvadza zvomukati.

The mabasa inogona kuverengwa pakati mutemo tembiricha iri striated musculature, sezvo rinowanika Kushanduka zvikuru kupisa chete zvinoshingaira tsandanyama marwadzo. Ndicho chikonzero kana peremerzanii tsandanyama dzinotanga kubvunda involuntarily.

Mashandiro anoita wakatsetseka tsandanyama tishu

Musculature iyi mhando anoita kubvisa chaitika. It iri pakuti anotsvedzerera tsandanyama zviri ura kusunda pachituru kunzvimbo kuchaitwa yavo kubva mumuviri. Uyewo, basa iri kunoratidzwa pakuzvarwa, kana kumeso tsandanyama pamusoro dumbu kusunda zvibereko zvomuviri.

Mashandiro anoita kumeso tsandanyama rinenge havana shoma. Uyewo chinhu chinokosha sphincter yavo. Jira yakadaro inoumbwa chaiwo dzeraundi tsandanyama kuti anogona occlude uye akazaruka. Sphincters varipo vari Urinary turakiti, ari dumbu, pakati mudumbu uye yegurokuro, nenduru dundira, ari mudzidzi.

Chimwe chinokosha basa anotsvedzerera tsandanyama - paumbwe ligamentous midziyo. Zvakakosha kuramba akarurama chinzvimbo zvomukati. By achideredza mataurire tsandanyama idzi prolapse dzimwe nhengo anogona kuitika.

At ichi basa kumeso tsandanyama magumo.

Chinangwa pomwoyo

Pano, pfungwa, hapana inokosha kutaura. Huru uye chete kushanda zvinyama ichi - kupa ropa kuparadzirwa mumuviri.

Mhedziso: The misiyano pakati vatatu mhando tsandanyama tishu

Nokuti Kuziviswa nyaya ratinoparidza tafura:

Ndizvo zvose zvinokosha zvinoitwa striated, kumeso uye cardiac tsandanyama tishu. Zvino imi muri vanoziva mabasa avo, mamiriro, uye zvikuru kusiyana uye zvakafanana.
