Eyona eziphambili ze iiseli

Emzimbeni, izityalo kunye nezilwanyana cell iintlobo ezahlukeneyo weeseli zeethishu. Amalaphu ingaba nomahluko njengolwakhiwo yeseli, kwaye ubume isizalo extracellular, kwakunye nemisebenzi yazo. iintlobo ezahlukeneyo iseli zinokuba nomahluko ngaphezu imilo, ubukhulu, ubukho okanye ukungabikho organelles ezithile. Iintlobo ngeentlobo zeeseli ezenza iintlobo ezahlukeneyo izicwili. Cinga iintlobo eziphambili iiseli.

Imifuno, mushroom, isilwanyana, elingena

Le ukuhlelwa iiseli, kuxhomekeke eziphilayo eyakhelwe. Nantsi itshati uthelekiso, nto leyo ibonisa iintlobo iiseli, iiyantlukwano zabo ezifanayo.

Iintlobo iiseli izicwili ezahlukeneyo

iiseli ezahlukeneyo ibe kwithishyu. Ukongeza, omnye kunye laphu efanayo ubunjwe iintlobo ngeentlobo zeeseli.

iiseli epithelial

Zibizwa ngokuba iiseli epithelial. Oku iiseli differentsiirovannye polar zibekwe kufutshane omnye komnye. Bangafika cubic, platy okanye imilo zezindlu. iiseli Epithelial ngokuqhelekileyo akhiwe kwi ndizayo Uhlobo Lokuqala.

Iintlobo iiseli zomzimba nokuqina

kwizicwili Kukho iintlobo ezininzi:

• reticular;
• ezinezikhondo ekhasa;
• ifayibha okubi;
• ithambo;
• intlala;
• fat;
• igazi;
• nkovu.

Nganye kwezi kwinyama Unazo iintlobo zeeseli kweziyobisi intercellular. Reticulum iqulathe reticulocytes neefayibha reticular. Of reticulocytes bangaba iiseli hematopoietic kunye macrophage - iiseli vutihlamuleri byakwe ku lwela umzimba iintsholongwane.

Inyama ashinyeneyo ezinezikhondo iqulathe ncakasana kwimicu kunye evakalala - ukusuka iziyobisi amorphous. I ashinyeneyo ezinezikhondo isicwili luthambe unika abasemagunyeni, yaye evakalala Wawuzalisa ngokulungileyo izikhewu phakathi kwamalungu zangaphakathi.

Bone inyama iqulethe iindidi ezahlukeneyo iiseli: osteogenic, osteoblasts, osteoclasts, kunye osteocytes. Le yokugqibela iiseli ezisisiseko kwithishyu. Osteogenic - iiseli undifferentiated enokuthi ibe ithambo iiseli, osteoblasts kunye osteoclasts. Osteoblasts ukuvelisa izinto ezakha matrix extracellular ithambo. Osteoclasts banoxanduva resorption esiqwini ithambo, xa kukho imfuneko. Ezinye izazinzulu musa ukuba iiseli ithambo.

inyama intlala ibandakanya chondrocytes kunye chondroblasts chondroclasts. Eyokuqala kule nwebu zangaphandle intlala. Zinelungelo imilo fusiform. Chondroblasts akhiwe kule nwebu engaphakathi. Baye okweqanda okanye imilo setyhula. Chondroclasts inoxanduva nokulahlwa iiseli ezindala intlala.

inyama Adipose ibandakanya omnye kuphela uhlobo iiseli: adipocytes. Bathi ziqulathe isixa esikhulu ngamanqatha nanceba.

Iintlobo ngeentlobo iiseli zegazi kunye nkovu

Igazi iqulethe iintlobo ezininzi iiseli, ekuthiwa ziiseli igazi. Eli igazi elibomvu iiseli, iiplatelets kunye neeseli zegazi ezimhlophe, apho zohlulwa ngokwendidi eziliqela. Erythrocytes abe imilo setyhula atshabalalisa. Aqulathe yihemoglobin, nto leyo umsebenzi - ukuthuthwa ioksijini wonke umzimba. Zegazi - ezincinane iiseli non-nuclear. Abanoxanduva ekunqandeni igazi. Leukocytes ukuba amajoni omzimba abantu kunye nezilwanyana.

iiseli ezimhlophe zegazi bohlulwa babe ngamaqela amabini eziphambili: granular kunye nezernistye. I yangaphambili ziquka neutrophils, eosinophils, kunye basophils. Eyokuqala ziyakwazi phagocytosis - ukudla kwiintsholongwane ezinobutshaba. Eosinophils nazo ziyakwazi phagocytosis, kodwa oku indima zazo eziphambili. Owona msebenzi wawo ukuba atshabalalise histamine eyakhutshwa ezinye iiseli ngexesha lenkqubo kwiintetho ezikralayo, nto leyo ibangele ukudumba. Basophils ukulamla nangokurhala, cell eosinophil chemotactic factor.

Nezernistye leukocytes zahlulwe lymphocyte kunye monocytes. Eyokuqala yahlulwe iiklasi ezintathu, kuxhomekeke kwimisebenzi yabo. Kukho T-iiseli, iiseli B kunye neeseli null. B iiseli unoxanduva ukuvelisa antibodies. iiseli T banoxanduva ingqalelo iiseli amazwe, nokukhuthazwa umsebenzi B-lymphocyte kunye monocytes. Zero lymphocyte kubekelelwe.

Monocytes okanye macrophage, nazo ziyakwazi phagocytosis. Konakalisa iintsholongwane neebhaktiriya.

inyama novalo

Ezi ndidi zilandelayo iiseli zemithambo-luvo:

• luvo efanelekileyo;
• glia.

iiseli zemithambo-luvo zibizwa ngokuba iiseli zemithambo-luvo. Ziqulethe ithole kunye neenkqubo: Umzobo wesi elide kunye dendrite mfutshane eyayizalwa. Ngabo unoxanduva lokuqulunqa noncedo transfer. Kuxhomekeka inani propagules waba unipolar (omnye), disorder (emibini), kunye multipolar (a Ukuba kwisininzi) luvo ekwanti. Multipolar ixhaphakileyo abantu nezilwanyana.

iiseli Glial asebenza kunye nemisebenzi lokudla uvumela ukufakwa isitali isithuba kwaye unikezelo mzimba luvo.

cells kwemisipha

Zibizwa myocytes, okanye imicu. Kukho ezintathu iintlobo esiqwini imisipha :

• striated;
• intliziyo;
• egudileyo.

Ngokuxhomekeka kuhlobo izihlunu, myocytes ezahlukileyo. Xa tissue striated zinde, laphela, kufuneka umphakathi eziliqela yaye inani elikhulu mitochondria. Ngapha koko, ukuba uyahambelana. Smooth ijwabu kwemisipha luphawulwa myocytes ezincinane kunye nuclei ezimbalwa kunye mitochondria. Smooth ijwabu kwemisipha lingenako kuncitshiswa ngokukhawuleza kangangoko striated. Le umsipha ubunjwe iiseli izihlunu, zifana nezo kwithishyu striated. Zonke myocytes ziqulathe iiproteni contractile: actin kunye myosin.
