I-Epithelium

I-epithelium iwuhlobo lwesicubu esakhiwe ungqimba olulodwa noma ngaphezulu lwamangqamuzana amboza ubuso bomzimba, alayini imigodi yangaphakathi nezitho, futhi akhe izindlala. Lesi sicubu sisebenza imisebenzi eminingana ebalulekile ehlanganisa ukuvikela, ukumuncwa, ukuhlunga, ukukhipha, ukufihla, nokwamukela izinzwa. Amaseli e-Epithelial zipakishwe ngokuqinile, zinendawo encane ye-intercellular, futhi zinamathiselwe ongqimbeni oluncane lwezicubu ezixhumeneyo ezaziwa ngokuthi ulwelwesi olungaphansi, oluzisekela futhi luzihlukanise nezicubu ezingaphansi.

Ngokuvamile lolu hlobo lwesicubu lutholakala kuphi?

Izicubu ze-epithelial zitholakala kuwo wonke umzimba, zombili zimboza izindawo ezingaphandle kanye nolwelwesi lwezikhala zangaphakathi nezakhiwo. Ezinye izibonelo zihlanganisa:

• Isikhumba: Sakha isembozo sangaphandle somzimba, sivikela ekuphelelweni amanzi emzimbeni, ekulimaleni, nasezifweni. Ingaphezulu lenziwe ngezinto ezikhethekile ama-squamous cell.
• I-Digestive tract: Ihlanganisa umlomo, umminzo, isisu, amathumbu kanye ne-rectum, yenza kube lula ukumuncwa nokuphuma.
• Isistimu yokuphefumula: Ihlanganisa imigudu yamakhala, uqhoqhoqho, namaphaphu, okuhlanganisa ukungena kanye nokugcinwa komswakama. Lolu hlobo lwezicubu lubizwa ngokuthi i-epithelium yokuphefumula.
• Isistimu yomchamo: Ihlanganisa izinso, ureters, isinye, kanye ne-urethra, ebandakanyeka ekuhlungeni nasekuphumeni. Lolu hlobo lwezicubu lubizwa ngokuthi i-urothelium.
• Amapheshana okuzala: Izakhiwo zemigqa kuzo zombili izinhlelo zokuzala zabesilisa nabesifazane, ezibandakanyeka emisebenzini eyahlukene yokuzala.
• Izindlala: Zombili izindlala ze-endocrine (ukukhulula amahomoni ngqo egazini noma i-lymph) kanye ne-exocrine (ukukhulula izinto ngemibhobho eya endaweni ye-epithelial) ziphuma kuzicubu ze-epithelial.

Hlobo luni lomdlavuza oluqala kumaseli ku-epithelium?

Umdlavuza ovela kumaseli e-epithelial aziwa ngokuthi umdlavuza, futhi ziwuhlobo oluvame kakhulu lomdlavuza. Izinhlobo ze-carcinomas zihlanganisa:

• I-squamous cell carcinoma: Isuka ku i-squamous epithelium ezitholakala ezindaweni ezifana nesikhumba, umlomo, umminzo, nolwelwesi lwamapheshana okuphefumula nokugaya ukudla.
• I-Adenocarcinoma: Isuka ku okuyindlala amangqamuzana e-epithelial amugqa noma amboze izitho ezifana nebele, i-prostate, iphaphu, isisu, amanyikwe, kanye nekholoni.
• I-Basal cell carcinoma: Uhlobo oluvame kakhulu lomdlavuza wesikhumba, oluvela ku- amaseli e-basal ku-epidermis.
• I-urothelial carcinoma: Iqala ku-urothelium, ehlanganisa isinye, i-ureters, nezingxenye zezinso ne-urethra.
• I-renal cell carcinoma: Kuvela kumaseli e-epithelial we-renal tubules ezinso.

Ukuhlonzwa nokuhlukaniswa kwe-carcinomas kubalulekile ekunqumeni amasu okwelapha aphumelela kakhulu, njengoba izinhlobo ezahlukene zomdlavuza we-epithelial zingahluka kakhulu ekuziphatheni, ekusakazeni, nasekuphenduleni ekwelashweni.
