Inyama yabantu

inyama lomntu isakhiwo zeeseli abantu extracellular, ngokwembali. isakhiwo ngamnye uneempawu ezithile morphological kwaye esebenza ukuba ethile kuyo. Emzimbeni ukusebenzisana yonke inyama yabantu. Oku inika umanyano morphological kwaye esebenza kuyo.

Types of inyama yabantu

Kukho iintlobo ezine izakhiwo cell. Xa umzimba kukho epithelial, luvo, izihlunu kunye zomzimba nokuqina.

Umda (epithelial) isakhiwo iqulathe iiseli epithelial ngakwimida phezu nemingxuma omzimba kunye inwebu kwiinwebu izibilini emzimbeni kwaye zenze esinobubovu kunye secretion ngaphakathi langaphandle.

Iiseli zobuchopho epithelial yabantu olunga- phakathi isifo, ibekwe ndizayo ongaphantsi. Umphezulu engaphakathi kwale maleko lijongene ngqo yemeko ezisingqongileyo. Ukutya loo inyama epithelial ikhutshwa phandle nokuhanjiswa ioksijini kunye nezinto nge ongaphantsi inwebu kwemithambo yegazi.

Kuxhomekeka imilo iseli zihlelwe tyaba (eluswini), zezindlu (emathunjini), cubic (capsule sezintso glomerulus) umaleko. Kuxhomekeka nenani lamanqanaba ukwahlula abangatshatanga kunye multilayer ilaphu. Ukuba zonke iiseli isakhiwo inwebu iyazalisekiswa, oko epithelium esinee-single-. Xa iiseli inwebu-bakhonkxiwe kumqolo omnye, ngoxa abanye ukuba zikhululekile, oko - a epithelium multilayered. A single-umaleko epithelial inyama kunokuba single-core okanye multi-core. Oku kuxhomekeke kwinqanaba apho eziba khona amaziko. Kwezinye iimeko ezikhoyo kubume ejongene sangaphandle bume ciliary isiliya.

Isakhiwo angafaniyo kakhulu kwizicwili yinto yabantu. Nangona kunjalo, bonke Ukrainian lunee ntlobo zalo akhiwa mesenchymal (phakathi intsholongwane umaleko). Ngokudibanisa sakhiwo kufuneka lichazwe ezinezikhondo, cartilaginous, emithanjeni, izicwili hematopoietic kunye negazi. Zonke ezi ntlobo bangamalungu isakhiwo engaphakathi eliphakathi.

Igazi oqulethe izinto esizicelayo: zegazi, iiseli ezimhlophe zegazi, iiseli ezibomvu. Ukongeza, ukuba sele plasma ulwelo. na emzimbeni, imizimba omzimba, izondlo plasma. Xa umongo wethambo (ebomvu) na inyama hematopoietic. Kwiindawo nkovu, lo isifo isisu, isibindi, udakada, thymus isakhiwo emithanjeni ibekwe kunye namanye amaziko.

Nokuqina izihlunu ezinezikhondo isakhiwo, ngaphandle iiseli, yaye ziquka nezinye izinto. Bona, ingakumbi, ubonisa eliphakathi zimelwe ngokohlobo collagen, elastin, argiofilnyh neerhali reticular leyo afakwe kulo mbandela isiseko.

Zonke ancedisana zitho Imicu zeethishu langoku nokuqina. Noko ke, ukuba kugqame kakhulu apho kukho umthwalo omkhulu ngomatshini.

Ubume lithambo iiseli ithambo langoku. Bona bayakwazi zenze eliphakathi, ebandakanya kunye neetyuwa kwezimbiwa kwakunye kwimicu zeethishu nokuqina.

Ukuma cartilaginous yahlulwe hyaline, ilastiki kunye fibrocartilage. Xa fibrocartilage chondrin iqulethe isixa elaneleyo kwimicu collagen ukuze libanike ngamandla intlala. I-elastic intlala chondrin umaleko ngaphandle collagen, imicu elastic yaye iquka iiseli intlala, ngaloo unezinga elithile luthambe. isakhiwo Hyaline ngokwaneleyo ashinyeneyo, kodwa ngaphantsi yomelela kuthelekiswa nabanye.

Kwezihlunu zomuntu ziquka izihlunu intliziyo, anencasa imicu striated. Ngenxa kule sakhiwo, unciphiso iphumile imithambo yegazi, enyama yangaphakathi, kwakunye nentshukumo yamalungu omzimba wenziwe. Ukuncitshiswa zihlunu striated kwenzeka ngokuthanda komntu. imisipha intliziyo neerhali agudileyo ifakiwe isakhiwo nezibilini. Nabo balukayo abawuthobeli ncam kwiminqweno umntu.
