Izinhlobo ezinkulu amaseli

Emzimbeni, izitshalo nezilwane secrete izinhlobo ezahlukene izicubu amaseli. Kwangezikhathi kungaba ezahlukene njengoba isakhiwo cell, kanye nesakhiwo matrix extracellular, kanye nemisebenzi yabo. Abahlukahlukene zamangqamuzana zingahluka kuka ukuma, ubukhulu, khona noma ukungabi khona organelles ezithile. izinhlobo ezihlukene zamangqamuzana ukwakha izinhlobo ezahlukene kwezicubu. Cabangela izinhlobo ezinkulu amaseli.

Vegetable, amakhowe, isilwane, webhaktheriya

Lokhu kuhlukaniswa amaseli, kuncike eziphilayo zakhiwa. Nasi ishadi ukuqhathanisa, elibonisa izinhlobo zamangqamuzana, ukungaboni ngaso linye kwabo ngazo nezinto ezifana ngazo.

Izinhlobo amaseli kwezicubu ahlukahlukene

amaseli abahlukahlukene ezahlukene yakha izicubu. Ngaphezu kwalokho, omunye futhi lendwangu efanayo yakhiwa izinhlobo eziningana ezihlukene zamangqamuzana.

amaseli EPITHELIAL

Zibizwa ngokuthi amaseli EPITHELIAL. Lokhu polar differentsiirovannye amaseli elise eduze komunye nomunye. Kungenzeka cubic, platy noma ukuma cylindrical. amaseli EPITHELIAL kuvame esisogwini ulwelwesi basal.

Izinhlobo zezinzwa izicubu amaseli

ezicutshini Kunezinhlobo eziningana:

• reticular;
• fibrous obukhulu;
• fibre okuxekethile;
• ithambo;
• uqwanga;
• amafutha;
• igazi;
• lymph.

Ngayinye yalezi kwezicubu possesses ezihlukahlukene amaseli nempahla intercellular. Reticulum siqukethe reticulocytes yemisipha reticular. Of reticulocytes ungakheka amaseli hematopoietic futhi macrophage - amaseli obhekene ekuvikeleni umzimba ukulwa namagciwane.

I obukhulu izicubu fibrous siqukethe ngokuyisisekelo imicu kanye okuxekethile - kusukela izidakamizwa amorphous. I obukhulu fibrous izicubu kuyaqina unikeza iziphathimandla, athukulule igcwalisa igebe phakathi kwezitho zangaphakathi.

Bone izicubu siqukethe izinhlobo ezihlukene zamangqamuzana: osteogenic, osteoblasts, osteoclasts, futhi osteocytes. I yamuva ayizona izicubu eziyisisekelo amaseli. Osteogenic - namangqamuzana undifferentiated ezingaba yakha ithambo amaseli, osteoblasts futhi osteoclasts. Osteoblasts ukukhiqiza izinto ezakha matrix extracellular ithambo. Osteoclasts banesibopho resorption ithambo izicubu, uma kunesidingo. Abanye ososayensi musa uzise ithambo amaseli.

izicubu Uqwanga siqukethe chondrocytes futhi chondroblasts chondroclasts. Eyokuqala e olwelwesini uqwanga. Sinenkosi simise fusiform. Chondroblasts ise ungqimba kwangaphakathi. Sinenkosi okweqanda noma ukuma isiyingi. Chondroclasts obhekene anawo uqwanga amaseli ubudala.

izicubu Adipose siqukethe uhlobo olulodwa kuphela amaseli: adipocytes. Ziqukethe semali amafutha ezisele.

A ezihlukahlukene egazi kanye lymph

Igazi liqukethe izinhlobo eziningi cell, elibizwa ngokuthi egazi. Lokhu igazi amangqamuzana abomvu, izinhlayiya zegazi kanye egazi amhlophe, okuyinto zihlukaniswe izinhlobo eziningana. Erythrocyte abe isicaba ukuma isiyingi. Bona aneprotheni i-hemoglobin, okuyinto umsebenzi - ukuthwala umoya-mpilo wonke umzimba. Ama-platelet I - encane amaseli non-izikhali zenuzi. Bazi ukuthi banesibophezelo igazi ekunqandeni. Leukocyte bangabantu futhi isilwane izivikeli mzimba.

Amangqamuzana amhlophe egazi zihlukaniswe amaqembu amabili ayinhloko: luyimbudumbudu futhi nezernistye. Lo mqeqeshi owake wapheka zihlanganisa ama-neutrophil eosinophils, futhi basophils. Eyokuqala labo abazokwazi phagocytosis - ukudliwa amagciwane ezinenzondo amagciwane. Eosinophils nazo uyakwazi phagocytosis, kodwa lokhu akulona indima yabo eyinhloko. umsebenzi ngokuyinhloko ukubhubhisa histamine ezikhishwe kwamanye amangqamuzana ngesikhathi ukuvuvukala, okungase kubangele ukuvuvukala. Basophils sokulamula ukuvuvukala secrete eosinophil chemotactic isici.

Nezernistye leukocyte zihlukaniswe lymphocyte futhi monocytes. Esokuqala yizigaba ezintathu, kuye ngokuthi imisebenti yabo. Kukhona T-cell, B cell kanye amaseli null. B cell obhekene kokukhiqiza amasosha omzimba. T cell banesibopho ukuqashelwa lamaseli lesinye isizwe, futhi ukukhuthazwa umsebenzi B-lymphocyte futhi monocytes. Zero lymphocyte agodliwe.

Monocytes noma ama-macrophage, futhi uyakwazi phagocytosis. Ayayona amagciwane namagciwane.

izicubu sezinzwa

Lezi zinhlobo ezilandelayo njengoba amangqamuzana ezinzwa e:

• ezinzwa efanele;
• glia.

Njengoba amangqamuzana ezinzwa e abizwa ngokuthi izinzwa. Zakhiwa nethole izinqubo: Axon eside futhi dendrite iDemo ekhelini. Ziyakwazi ukwakheka kanye nomfutho yokudlulisa. Kuye inani propagules ukuthi angawodwa unipolar (owodwa), okuguquguqukayo (ezimbili), kanye multipolar (sebuningini) izinzwa. Multipolar evamile kubantu nasezilwaneni.

amaseli Glial isebenze futhi lokudla imisebenzi okuvumela ukubekwa esitebeleni isikhala kanye supply izakhamzimba izinzwa.

imisipha amaseli

Zibizwa ngokuthi myocytes, noma zesivikelo sesifuba. Kunezinhlobo ezintathu izinhlobo kwemisipha izicubu :

• striated;
• inhliziyo;
• bushelelezi.

Kuye ohlotsheni izicubu, myocytes zihlukile. Ngo izicubu striated bade, side, babe cores eziningana futhi inani elikhulu mitochondria. Ngaphezu kwalokho, munye. Smooth kwemisipha izicubu libhekene myocytes encane nge nuclei okumbalwa mitochondria. Smooth kwemisipha izicubu akakwazi zingancishiswa ngokukhulu ukushesha striated. Imisipha yenhliziyo yakhiwa imisipha amaseli, zifana nalezo izicubu striated. Zonke myocytes aqukethe amaprotheni contractile: actin futhi myosin.
