Iiseli engenamqheba: iimpawu zezakhiwo, iinketho amagama kunye nendawo eyendawo

Umzimba womntu - ke izigidi iiseli iimilo ezahlukeneyo, iintlobo kunye nobukhulu. Bona zincinane kakhulu ukuba siqwalasele ndibahlolisise kuphela phantsi ngemicroscope. Enyanisweni, iiseli - i iibhloko zokwakha kakhulu ngenxa yethemba izihlunu, amalungu, iinkqubo kunye nezinto eziphilayo yonke. Nangona umahluko neefom zonke iiseli yi umzobo jikelele eso sakhiwo. Ziqulethe i inwebu sangaphezulu, ngumongo engundoqo kunye icytoplasm semiliquid. Malunga neentlobo ezahlukeneyo iiseli kunokuba intetho elide, kodwa eli nqaku liza kuthathelwa ingqalelo uhlobo olunye kuphela, ekuthiwa ziiseli engenamqheba. Siza kuzama ukuqonda ukuba yintoni na, ukuba ibekwe khona ukuze izinto zihambe njani na.

ongakhetha isihloko

iiseli ezinjalo zaziwa phantsi amagama eziliqela. ibinzana elithi "enterocyte engenamqheba", "engenamqheba ekzokrinotsid" yaye "engenamqheba grandulotsit" lidla ngokusetyenziswa. iiseli engenamqheba Latin ekuthiwa enterocytus caliciformis. Maxa wambi igama elithi "neendebe iseli," nto leyo ebhekisela iiseli engenamqheba. Zonke ezi magama lilingana omnye komnye kwaye lusetyenziswe ntonye.

Igama wawubonisa imilo angaqhelekanga iiseli. Zibonakala njenge ende, iglasi emxinwa idlabhuzwe kancinci phezulu.

Iiseli yale hlobo kwakucingwa ukuba epithelium le inwebu yangaphakathi kwaye benza kwimveliso yencindi yomlomo. Zikhona emzimbeni ezingabantu nezilwanyana.

Eyendawo. amathumbu

iiseli engenamqheba yinxalenye yimibutho eyahlukeneyo epithelial. Enye iindawo eyendawo - amathumbu. epithelium isisu has isakhiwo kunokuba ezintsonkothileyo. Luhlanganisa iintlobo ezininzi enterocytes, kuquka limbic, engenamqheba, acidophilus, beskaemchatye, yonyango, kunye nezinye kakuhle umohluko. Bonke bephela amadlala elilodwa olunye-kunye nemisebenzi eyahlukeneyo. Ngokomzekelo, iiseli limbic epithelial abandakanyeka Parietal yokwetyiswa ukufunxeka. Engenamqheba unoxanduva lokuyila yencindi yomlomo (bona ngezantsi intetho ngaphezulu). iiseli Ezingokuqandusela ukuvelisa iihomoni phecana, iiseli acidophilus Punnett uvelise enzyme ngakumbi. Umsebenzi iiseli undifferentiated - nokuhlaziya ngokutsa epithelium.

iiseli engenamqheba yethumbu zibekwe phezu villi emathunjini. Zakhiwa ngamatsha kwi enye phakathi kwiiseli limbic. Kwi inxalenye apical ye villi kunye ezingontsingontsini tubular le inwebu yangaphakathi, ebizwa amadlala liberkyunovymi okanye crypts isisu, iiseli engenamqheba akafunyanwa. Nangona kukho iimeko ezinqabileyo.

In emathunjini amancinci yale hlobo iiseli ezinkulu. 9.5% enterocytes - iiseli engenamqheba epithelial. Ngaphezu koko, kwandisa inani labo ekuyeni colon distal. nombala zisasazwe phezu komphezulu wenqwelwana le crypts kunye villi, ezincinane labo elininzi villi ngokwabo.

yomoya

Enye indawo kwasendaweni engenamqheba iiseli exocrine - iphecana sokuphefumla. Apha kule seli phantse-30% ye-epithelium. Iiseli ikwalungiswe zibangele. Bona ziqulathe vacuoles ezaliswe secretion yangaphakathi. Vacuoles ekwandiseni inxalenye apical. Intamo isabelo seli liqulathe zakhiwo Golgi kunye mitochondria ezininzi. Umgudu engenamqheba cell microvilli inikezelwa, leyo, emva yencindi baba buqapheleke.

yencindi into oguquguqukayo kwindalo, nto zixhomekeke imiba yangaphandle, ukutsho oko lobushushu nokufuma.

cells engenamqheba Conjunctival

Indawo esilandelayo eyendawo kweeseli wayifinca - amehlo conjunctiva. Ezi isifo conjunctival baninzi. Le mfihlelo, secreted yi ezi seli yahlukile kwi yencindi secreted kwi epithelium zeminye imibutho. iiseli engenamqheba Conjunctival ingabekwa umaleko carcinomas ke mbhoxo, setyhula. Yencindi, abathi nokulungelelanisa kwaye cell, ebotshiwe uhlobo lomsebenzi womnatha libamba ingxelo namaqumrhu angaphandle kunye neentsholongwane. Ngeli ebengezelayo, i-network eyaphukileyo lususwa ngohlangothi medial, asuse amehlo ukusuka kobutyobo kunye neentsholongwane.

iiseli engenamqheba kule pancreas

iiseli engenamqheba ezisegumbini imibhobho yokuphuma zepancreas. Azikho kwi yonke ubude duct, yaye inxalenye yawo ebanzi. Kukho exocrine ndlala kwakhiwa isifo.

ndlala Parotid

Le ndlala amathe kwakhona zizityebi iiseli engenamqheba. Bona zibekwe kufutshane emlonyeni cell yencindi, ukukwazi ukufezekisa umqobo imichiza njengomhlaba. Nge ubudala, inani leeseli wayifinca kwi kwamadlala amathe lifinyele. umqobo elwa buthathaka.

Funda ngaphezulu malunga neempawu

iiseli engenamqheba ukuvelisa yencindi ezingenakunyibilika into ekuthiwa mucin. Mucin olunga- isifo, maxa wambi engapheliyo okusuka 1.5 mm. Ukuze enze oko, granules mutsitogennye ukufunxa amanzi adumbe. Yencindi kweeseli engenamqheba inemisebenzi eziliqela. Esiswini, injeke nakumathumbu isifo moisturizes ukuba imizimba kukhuthaza esiswini kunye neziqulatho isisu, yinxalenye ekugayeni eludongeni. Le conjunctiva ngaphandle humidification la engenamsebenzi akhuselayo kwamadlala amathe - umqobo.

Izilwa engenamqheba cells

Ngesiqhelo omzimba ukuba engenamqheba iiseli abangekhoyo egazini. Ukuba uhlalutyo igazi emthanjeni lachonga ngayo ezi zithinteli, oko kuthetha ukuba isigulana umntu okwenziwa sisilonda sikabhobhosi. Ngoko ke, omzimba uhlalutyo iseli wayifinca ezimiselweyo umahluko izifo ezingapheliyo namathumbu arhabaxa.
