The Mhando chikuru masero

Mumuviri, zvinomera uye mhuka secrete-siyana tishu masero. Nemicheka zvinogona kusiyana sezvo muchitokisi mamiriro, uye urongwa extracellular chizvaro, uyewo avo mabasa. Various Sero mhando zvingave zvakasiyana pane chimiro, ukuru, kuvapo kana kusavapo kwemamwe organelles. Mhando dzakasiyana masero nokuumba rakasiyana-siyana munyama. Funga Mhando chikuru masero.

Muriwo, howa, mhuka, kwemabhakitiriya

kupatsanura Masero aya, zvichienderana zvipenyu dzinovakwa. Heino nokuenzanisa chati, izvo zvinoratidza mhando masero, kusiyana kwavo uye zvakafanana.

Mhando masero munyama siyana

masero Various siyana vanoumba tishu. Mukuwedzera, mumwe uye chinokosha chete rinoumbwa pakubhadhara akasiyana siyana emasero.

masero epithelial

Dzinonzi masero epithelial. Izvi polar differentsiirovannye masero yaiva pedyo nepedyo. Vangave cubic, platy kana cylindrical chimiro. Masero Epithelial kazhinji iri basal membrane.

Mhando connective tishu masero

Connective zvinyama Kune mhando dzakawanda:

• reticular;
• batana fibrous;
• anongoremberera faibha;
• pfupa;
• shwashwa;
• mafuta;
• ropa;
• node.

Mumwe nomumwe nyama idzi ane zvakasiyana siyana emasero intercellular fuma. Reticulum ine reticulocytes uye reticular fibers. Of reticulocytes zvingaite masero hematopoietic uye macrophages - masero basa mukudzivirira muviri kurwisa utachiona.

Rizere fibrous zvinyama rinoumbwa chaizvoizvo kuti fibers uye unzenza - kubva amorphous fuma. Rizere fibrous zvinyama elasticity anopa hurumende, uye kusazvibata kunozadza pakakoromorwa pakati zvomukati.

Bone rinenge rine mhando dzakasiyana masero: osteogenic, osteoblasts, osteoclasts, uye osteocytes. Ekupedzisira zvinhu zvinokosha tishu masero. Osteogenic - ndivo masero undifferentiated kuti zvingaite pfupa masero, osteoblasts uye osteoclasts. Osteoblasts berekai zvinhu anoumba extracellular chizvaro repfupa. Osteoclasts ndivo mhosva resorption remafupa rinenge kana zvakakodzera. Mamwe masayendisiti haana undodziisa pfupa masero.

Shwashwa zvinyama ine chondrocytes uye chondroblasts chondroclasts. Wokutanga ari rokunze paiva shwashwa. Vane fusiform chimiro. Chondroblasts iri yomukati rukoko. Vane denderedzwa kana tenderera chimiro. Chondroclasts basa kurasira shwashwa masero akare.

Adipose zvinyama ine chimwe chete mhando masero: adipocytes. Inosanganisira yakawanda kupembedza mafuta.

A siyana masero eropa uye node

Ropa rine marudzi akawanda masero, akadana masero eropa. Iri ropa masero matsvuku, maplatelet uye masero eropa, izvo rakakamurwa marudzi anoverengeka. Erythrocytes vane flattened tenderera chimiro. Ivo ane puroteni inonzi hemoglobin, ndicho Zvaiitwa - the chokufambisa reokisijeni rose muviri. Maplatelet - duku non-zvenyukireya masero. Ivo ndivo kweropa. Leukocytes muri munhu uye mhuka zvirwere.

masero eropa machena rakakamurwa mapoka makuru maviri: granular uye nezernistye. Aimbova zvinosanganisira neutrophils, eosinophils, uye basophils. Wokutanga vanokwanisa phagocytosis - pokudya utachiona utsinye uye wanda. Eosinophils vari kugonawo phagocytosis, asi ichi hachisi chavainyanya basa. chikuru basa ravo kuparadza histamine aburitswa nemamwe masero panguva kushoma, izvo zvinogona kukonzera kuzvimba. Basophils svitsanisa kuzvimba uye secrete eosinophil chemotactic chikonzero.

Nezernistye leukocytes akakamurwa lymphocytes uye monocytes. Chokutanga rakakamurwa nemakirasi matatu, zvichienderana mabasa avo. Kune T-masero, B masero uye masero null. B masero nebasa kugadzira antibodies. T masero vane basa kuzivikanwa masero vatorwa, uye kweiyi basa B-lymphocytes uye monocytes. Zero lymphocytes zvakachengeterwa.

Monocytes kana macrophages, muri kugonawo phagocytosis. Vanoparadza nemavhairasi uye utachiona.

huta tishu

Zvinotevera mhando masero etsinga;

• kwakakodzera tsinga;
• glia.

Masero etsinga vanonzi Tutsinga tunofambisa mashoko utwu. Zvinosanganisira mhuru pezvakaitwa: refu axon uye pfupi dendrite branching. Ivo basa nokuumbwa uye tichimhanya chinja. Zvichienderana nokuwanda propagules akanga voga unipolar (imwe), nedambudziko (mbiri), uye multipolar (a muzvizhinji) Tutsinga tunofambisa mashoko utwu. Multipolar Inonyanya muvanhu nemhuka.

masero Glial anoshanda uye muviri rutsigiro mashandiro kubvumira kugadzikana placement muchadenga uye nerubatsiro zvinovaka muviri kune Tutsinga tunofambisa mashoko utwu.

mhasuro masero

Dzinonzi myocytes, kana fibers. Kune zvitatu mhando tsandanyama tishu :

• striated;
• mwoyo;
• pachaenzaniswa.

Zvichienderana zvinyama mhando, myocytes zvakasiyana. In striated zvinyama vava refu, elongated, vane cores akawanda uye vakawanda mitochondria. Uyezve, vari zvakanyatsobatana. Smooth tsandanyama rinenge kunoratidzwa myocytes duku nuclei vashoma uye mitochondria. Smooth tsandanyama rinenge haasi kukwanisa kuderedzwa nokukurumidza striated. The pomwoyo rinoumbwa tsandanyama masero, zvakawanda zvakafanana striated tishu. myocytes All zvine contractile mapuroteni: actin uye myosin.
