Mashandiro anoita tsandanyama rinenge uye mamiriro mhando

Muviri mhuka dzose, kusanganisira vanhu, rinoumbwa pakubhadhara zvina zvinyama: epithelial, achitya, connective uye tsandanyama. On yokupedzisira ichakurukurwa munyaya ino.

Siyana tsandanyama tishu

Zvinokosha siyana matatu:

• striated;
• chechetere;
• mwoyo.

Mabasa ose tsandanyama rinenge dzakasiyana kwemarudzi akasiyana zvishoma. Uye mamiriro zvakare.

Apo vari tsandanyama rinenge riri mumuviri womunhu?

Muscle rinenge dzakasiyana kwemarudzi ipi yakasiyana nzvimbo mumuviri mhuka uye vanhu. Saka, kubva mumwoyo tsandanyama, sezvo zita rinoreva kuti inovakwa mwoyo.

Kubva striated skeletal tsandanyama kuumbwa tsandanyama tishu.

Smooth tsandanyama anomira mukati mhango, izvo zvinofanira kuderedzwa. Izvi Somuenzaniso, ura, dundira, dumbu, dumbu, etc.

tsandanyama maumbirwo siyana kwemarudzi-siyana. On hurukuro yake muudzame inotevera.

kuti tsandanyama rinenge sei?

It rine masero guru kadikidiki - tsandanyama masero. Ivowo vanonziwo faibha. Muscle masero nhaka multi-Musimboti uye vazhinji mitochondria - organelles anokonzera simba kugadzirwa.

Uyezve, nemamiriro tsandanyama pakati nyama dzevanhu uye mhuka inosanganisira kuvapo shoma intercellular fuma ine collagen, izvo zvinopa elasticity tsandanyama.

Ngatimboonai marongerwo uye kushanda tsandanyama rinenge dzakasiyana kwemarudzi voga.

Marongerwo basa wakatsetseka tsandanyama tishu

jira ichi inotongwa autonomic tsinga. Naizvozvo, munhu haagoni kuderedza tsandanyama nokungwaririra zvakavakwa rejira wakatsetseka.

Zvinonzi aumba kubva mesenchyme. Zviri rudzi embryo connective tishu.

Kunoderedza zvinyama uyu zvikuru sekwaserera uye nokukurumidza pane striated.

Enzanisa chinokosha inovakwa pamusoro myocytes fusiform chimiro rwakavakwa miromo. Kureba masero aya zvingava 100 kusvika 500 micrometers, uye pakukora - vanenge 10 micrometers. Mumasero zvinyama zviri mononuclear. Musimboti iri mu pakati myocyte. Uyezve, zvakanaka dzakabudirira organelles zvakadai mitochondria uye agranular EPS. Uyewo ari kumeso tsandanyama rinenge masero vari vazhinji glycogen inclusions, izvo zvinoumba reserves nezvinovaka muviri.

The chinhu kuti anopa rutapudzo kuti tsandanyama rinenge kwemarudzi, muri myofilaments. Vanogona kuvakwa zviviri contractile mapuroteni actin uye myosin. Dhayamita myofilaments kuti ine myosin, ndiyo 17 nanometers, uye avo vari kuvakwa pamusoro actin - 7 nanometers. Panewo zvenguva myofilaments vane dhayamita ndiyo 10 nanometers. Dzidziso longitudinal myofibrils.

Sechivako kwakadai tsandanyama rinenge anosanganisirawo extracellular chizvaro pakati collagen, iyo inopa kutaurirana pakati nomumwe myocytes.

Mabasa ose tsandanyama rinenge ino ehove

• Sphincter. Ndiko kwakanaka tsandanyama dzomuviri kurongwa nenzira raundi yokudzora zviri kuchinja muviri mumwe kana kubva chikamu mumwe muviri mumwe.
• Kubvisa. It iri yokuti anotsvedzerera tsandanyama kubatsira muviri excrete tsvina, uyewo mubasa muitiro yokusununguka.
• Kutanga vascular lumen.
• Paumbwe ligamentous midziyo. Pamusana kwaari, nhengo dzakawanda, zvakadai itsvo, dzinoitirwa panzvimbo.

Zvino ngatitarise muchimiro tsandanyama tishu.

Striated

It hunodzorwa ari somatic tsinga. Naizvozvo, murume anogona nokungwaririra chengetedza kwakadai tsandanyama. Kubva striated skeletal tsandanyama rinenge riri kuumbwa.

zvinyama ichi une fibers. Ndivo masero vane muzvizhinji kuti cores dzinongoda pedyo plasma membrane. Mukuwedzera, dzine yakawanda glycogen inclusions. Zvakanaka-dzakabudirira organelles akadai mitochondria. Ndivo pedyo contractile mumasero okunze. dzimwe organelles All dziri pedyo nuclei uye havaratidzi yakatanga.

Zvivako kuburikidza izvo muchinjikwa mitsetse jira ipfupi, muri myofibrils. dhayamita ravo pakati mumwe uye vaviri micrometers. Myofibrils kugara dzakawanda muchitokisi uye akaisa zvayo pakati. Dzidziso longitudinal myofibrils. Ivo anoumbwa chiedza nerima disks, rakatumbuka, iyo pave muchinjikwa "Striped" jira.

Mabasa ose tsandanyama rinenge kwakadai:

• Kupa muviri uchifamba muchadenga.
• Mhosva kwebasa nhengo dzomuviri hama kune mumwe.
• Anogona kuramba muviri mamiriro.
• Munyaya mutemo tembiricha: shoma rinoita tsandanyama, dzakanga tembiricha. Kana kuoma nechando striated tsandanyama vanogona kutanga kubata involuntarily. Izvi rinotsanangura kudedera muviri.
• Shumirai rwokudzivirira basa. Izvi ndezvechokwadi kunyanya pamusoro abdominal tsandanyama, izvo inodzivirira zhinji nhengo dzomukati kubva kukuvara.
• Ave chitoro remvura uye munyu.

Cardiac tsandanyama tishu

jira Izvi zvakafanana zvose striated, uye kumeso. Uyewo mvere, zviri nokudzorwa autonomic tsinga. Zvisinei, todzokera nayo sezvo nokushingaira sezvo striated.

Inoitwa masero anonzi cardiomyocytes.

Mabasa ose tsandanyama rinenge kwakadai:

• Zviri chimwe chete: kuti tibu- kufamba kweropa kuburikidza nomuviri.
