Smooth tsoka nama: tsarin fasali. The kaddarorin da santsi tsoka nama

Animal tsokoki yi wani muhimmanci sosai aiki a jikin halittu masu rai - tsari da kuma layin duk gabobin da kuma tsarin. Na musamman muhimmancin tsakanin wadannan tsoka yana wato, kamar yadda da muhimmancin a cikin samuwar cikin matsanancin da kuma na ciki rami na tsarin sassa na jiki na fifiko. Wannan talifin zai dubi abin da santsi tsoka nama, musamman tsarin da kaddarorin.

Irin wadannan tsokoki

The dabba kwayoyin yana da kadan tsoka iri:

• transversely sofane.
• m tsoka nama.

Dukansu biyu suna da nasu halayyar fasali na tsarin, ayyuka da kuma farfado da kaddarorin. Bugu da ƙari kuma, shi ne mai sauki rarrabe tsakanin su. Bayan duk, kuma duka suna da nasu musamman juna, wanda aka kafa ta hanyar kafa wani ɓangare na gina jiki aka gyara na sel.

Striated kyau ne zuwa kashi biyu main iri:

Sunan kanta nuna babban yankunan na jiki ta location. Its fasali su ne da muhimmanci sosai, saboda wannan ne musculature samar da wani ƙanƙancewa na zuciya, da motsi na wata gabar jiki da kuma duk sauran motsi sassa na jiki. Duk da haka, m tsoka da babu kasa mai muhimmanci. Mene ne ta fasali, la'akari da kara.

A general, shi za a iya gani cewa kawai da-hadewa aikin, yi da santsi da kuma striated tsoka nama, da barin dukan jiki zuwa aiki cikin nasara. Saboda haka, domin sanin fiye ko žasa da gagarumin na su ne ba zai yiwu ba.

Smooth tsoka nama: tsarin fasali

Basic m siffofin da wannan tsarin karya a cikin tsari da kuma abun da ke ciki na ta Kwayoyin - tsoka Kwayoyin. Kamar kowane sauran, wannan masana'anta da aka kafa ta a rukuni na Kwayoyin da suke da irin wannan a cikin tsarin, Properties, abun da ke ciki da kuma ayyuka yi. Common fasali na wani tsarin za a iya bayyana a 'yan sakin.

1. Kowane cell da aka kewaye da wani m tangle na connective nama zaruruwa, wanda yai kama da wani kwantena.
2. Kowane tsarin naúrar m ga sauran, da intercellular sarari ne kusan ba ya nan. Wannan damar dukan masana'anta da za a cushe, ginannun da kuma m.
3. Ba kamar striated takwarorinsu, wannan tsarin iya hada sel unequal siffar.

Wannan, ba shakka, ba dukan halaye da cewa suna da m tsoka nama. Features na tsarin, kamar yadda riga da doka qarya a myocytes kansu, su aiki da abun da ke ciki. Saboda haka, a kasa da batun shi za a tattauna a zurfafe.

Smooth tsoka myocytes

Myocytes ne na daban-daban siffar. Ya danganta da wurin a cikin wani musamman sashin jiki, za su iya zama:

• m.
• elongated fusiform.
• taso keya.
• Tsari.

Duk da haka, a cikin wani hali, da sauran abun da ke ciki shi ne kama da su. Sun dauke da wasu gabbansa, kamar:

• da bayyana, kuma aiki mitochondria.
• Golgi hadaddun.
• core, mafi elongated a siffar.
• endoplasmic reticulum.
• lysosomes.

Babu shakka, na al'ada da kuma cytoplasm inclusions ma ba. Sha'awa, m tsoka myocytes waje rufe ba kawai plasmolemma amma membrane (muhimmi). Yana bayar da su tare da wani ƙarin damar tuntubar juna.

Wadannan siffofin sa lamba sanya m tsoka nama. Saduwa da wuri da ake kira The Nexus. Ta hanyar su, kazalika da ta cikin pores, wanda a wadannan wurare suna samuwa a cikin membrane, bugun jini yana daukar kwayar cutar a tsakanin sel, bayanai musayar, ruwa kwayoyin da sauran mahadi.

Akwai wani sabon abu fasalin, wanda yana da santsi tsoka nama. Features na tsarin ta myocytes cewa ba dukkan su suna da jijiya endings. Me shi ne don haka muhimmanci Nexus. Abin daya cell ba ya zama ba tare da innervation, kuma da lokacinta za a iya daukar kwayar cutar ta hanyar da gaba tsarin kan masana'anta.

Akwai biyu na asali iri tsoka Kwayoyin.

1. Secretory. Su main aiki ne zamanin da jari na glycogen granules, rike da wani jam'i na mitochondria polysomes da ribosomal raka'a. Sunan tsarin asali daga sunadarai žunsa. Wannan contractile actin filaments da fibrin strands. Wadannan Kwayoyin suna da yawa sarrafa a periphery da nama.
2. Smooth tsoka zaruruwa. Suna da wani nau'i na elongated dogara sanda-dimbin yawa Tsarin dauke da wani m tsakiya canja zuwa tsakiyar keji. Wani sunan leyomiotsity.

Babban kaddarorin da nama

Kadarorin m tsoka dace ga waɗanda for striated. A wannan su a haɗe. Su ne:

• watsin.
• excitability.
• lability.
• contractility.

A daidai wannan lokaci, akwai kuma wata fairly takamaiman fasalin. Idan striated kwarangwal tsokoki iya sauri ji ƙyama (wannan yana da kyau kwatanta ta da tsãwa a jikin mutum), za ka iya santsi na dogon lokaci da aka gudanar a wani matsa jihar. Bugu da ƙari, da ayyukan ba batun nufin da tunanin mutum. Tun da shi SUPPLiES da autonomic juyayi tsarin.

A muhimmanci sosai alama ne da ikon zuwa rage tsawon lokaci tsawo (saukarwa) da kuma guda shakatawa. Saboda haka, wannan dogara ne a kan aikin da mafitsara. A karkashin mataki na nazarin halittu ruwa (da abun ciki) shi ne iya a miƙa sa'an nan ƙyama. Its ganuwar suna liyi tare da m tsokoki da shi.
