The mefuta e ka sehloohong ea lisele

'Meleng, limela le liphoofolo secrete mefuta e sa tšoaneng ea lisele lisele. Masela a ka ba e fapaneng ka ho sebopehong seleng, le sebopeho sa popeho kantle ho sele, hammoho le mesebetsi ya bona. mefuta e sa tšoaneng tsona seleng e ka 'na ba e fapaneng ho feta sebopeho sa, boholo, boteng kapa ba sieo ha organelles itseng. mefuta e fapaneng ea lisele eaba ba etsa mefuta e fapaneng ya lisele. Nahana ka mefuta e ka sehloohong ea liseleng.

Meroho, masheromo, liphoofolo, baktheria

tlhophiso ena ea lisele, ho itšetlehile ka lintho tse e hahoa. Mona ke papiso chate, e bontša mefuta ea lisele, ho se tšoane bona le ho tšoana.

Mefuta ea lisele tsa lisele tse sa tšoaneng

Tse sa tšoaneng lisele tse fapaneng theha dinama tse nyenyane tse. Ho phaella moo, e mong le lesela tšoanang e entsoe ka mefuta e 'maloa e fapaneng ea lisele.

lisele tse epithelial

Ba ba bitsoa lisele tse epithelial. Sena Polar lisele tse differentsiirovannye teng haufi le e mong le e tse ling. Ba ka 'na ba dikhubu, platy kapa sebopeho cylindrical. lisele tse Epithelial atisa ho fumaneha ka lera basal.

Mefuta ea lisele connective dinama tse nyenyane tse

Connective dinama tse nyenyane tse ho na le mefuta e 'maloa:

• reticular;
• le letšo-letšo fibrous;
• hlephileng faeba;
• lesapo;
• lefufuru;
• mafura;
• mali;
• lisele tsa mmele.

E mong le e ba lisele tsena o na le mefuta e fapaneng ea lisele le ho intercellular ntho. Reticulum na le reticulocytes le likhoele reticular. Ea reticulocytes ka theha lisele tse hematopoietic le macrophages - lisele tse nang le boikarabelo bakeng sa ho sireletsa 'mele khahlanong le likokoana-hloko.

The le letšo-letšo fibrous dinama tse nyenyane tse e na le e le hantle ya likhoele le hlephileng - ho tloha ntho amorphous. The le letšo-letšo fibrous dinama tse nyenyane tse elasticity fana ba boholong, 'me hlephileng tletseng ho likheo pakeng tsa litho tsa ka hare.

Bone dinama tse nyenyane tse e na le mefuta e fapaneng ea lisele: osteogenic, osteoblasts, osteoclasts, le osteocytes. Ea bobeli ke ea motheo lisele tse dinama tse nyenyane tse. Osteogenic - ke undifferentiated lisele ka theha lesapo lisele tse, osteoblasts le osteoclasts. Osteoblasts hlahisa dintho tse etsang popeho kantle ho sele ea masapo. Osteoclasts ba na le boikarabelo bakeng sa resorption ya dinama tse nyenyane tse lesapo, haeba ho hlokahala. Ba bang ba bo-rasaense ba se ke ba ise lisele tsa masapo.

Lefufuru dinama tse nyenyane tse e na le chondrocytes le chondroblasts chondroclasts. Ea pele ke ea lera ka ntle la lefufuru. Ba na le fusiform sebopeho. Chondroblasts sebakeng lera ka hare. Ba na le oval kapa sebopeho chitja. Chondroclasts nang le boikarabelo bakeng sa ho lahla ea lisele tsa khale lefufuru.

Adipose dinama tse nyenyane tse e na le mofuta o le mong feela ea lisele: adipocytes. Ba na le le leholo palo ea mafura a qenehela.

A mefuta e fapaneng ya lisele tsa mali le lisele tsa mmele

Mali e na le mefuta e mengata ea lisele tse bitsoang lisele tsa mali. Ena ea mali tse khubelu lisele tse, li-platelet le lisele tse tšoeu tsa mali, tse arotsoe ka mefuta e 'maloa. Erythrocytes na le pantshisi-tse chitja sebopeho. Ba na le protheine haemoglobin, e leng mosebetsi ya - ho tsamaisa oksijene ho pholletsa le 'mele. Liplatelete - tse nyenyane lisele tse bao e seng ea nyutlelie. Ba na le boikarabelo ba hoama ea mali. Leukocytes ke batho le liphoofolo sesole sa 'mele.

lisele tse tšoeu mali li arotsoe ka lihlopha tse peli tse khōlō: granular le nezernistye. Tsa pele kenyeletsa neutrophils, eosinophils, le basophils. Pele ba ka khona ho phagocytosis - ho ja libaktheria tletseng bora 'me likokoana-hloko. Eosinophils boetse ho na le ea nang le bokhoni ea phagocytosis, empa sena ha se karolo ea bona e khōlō. mosebetsi bona se seholo ke ho timetsa ba histamine lokolloa ka liseleng tse ling ka nako ya tshebetso a hlabang, e leng ho ka etsa hore ho ruruha. Basophils kena dipakeng tsa ho ruruha le secrete eosinophil chemotactic lebaka.

Nezernistye leukocytes ba arotsoe ka lymphocytes le monocytes. Pele e arotsoe litlelase tse tharo, ho itšetlehile ka mesebetsi ea bona. Ho na le T-lisele tse, lisele tse B le lisele tse null. lisele tse B le boikarabelo ba ho hlahisa lisireletsi. lisele tse T na le boikarabelo ba ho amohelwa ha lisele tse tsoang linaheng tse ling, 'me ho hlasimolla ba mosebetsi oa B-lymphocytes le monocytes. Lefela lymphocytes li sirelelitsoe.

Monocytes kapa macrophages, boetse ho na le ea nang le bokhoni ea phagocytosis. Ba timetsa likokoana-hloko 'me libaktheria li.

dinama tse nyenyane tse ea methapo

Latelang mefuta ea lisele methapo ea kutlo:

• methapo ea kutlo e loketseng;
• glia.

lisele tse methapo ea kutlo tse bitsoang methapo ea kutlo. Ba bopilwe ka namane le dithulaganyo: telele axon le lekgutshwanyane dendrite branching. Ba na le boikarabelo ba ho thehoe le botsitso phetiso. Ho itšetlehile ka palo ea propagules ile ka thōko monopolar (nngwe), ferekanyang (a mabeli), le multipolar (a plurality) methapo ea kutlo. Multipolar atileng ka ho fetisisa ho batho le liphoofolo.

lisele tse Glial sebetsa le phepo e nepahetseng tšehetso mesebetsi lumella placement setaleng sebaka le phepelo ke limatlafatsi ho methapo ea kutlo.

lisele tse mesifa

Ba ba bitsoa myocytes, kapa likhoele. Ho na le tse tharo mefuta e sa dinama tse nyenyane tse mesifa :

• striated;
• pelo;
• boreleli.

Ho itšetlehile ka mofuta o le dinama tse nyenyane tse, myocytes tse fapaneng. Ka dinama tse nyenyane tse striated ba nako e telele, o molelele o, na cores 'maloa' me palo e khōlō ea mitochondria. Ho feta moo, ba ile ba ba lohellana. Smooth mesifa dinama tse nyenyane tse e tšoauoa ka myocytes tse nyenyane le nuclei mmalwa le mitochondria. Smooth mesifa dinama tse nyenyane tse e sa khone ho fokotsoa kapele kamoo striated. The mesifa pelo e entsoe ka lisele tse mesifa, ho ka tšoanang le tsa dinama tse nyenyane tse striated. myocytes tsohle na le lihaha-'mele contractile: actin le myosin.
