Coupling of izicubu womuntu

ezicutshini zomzimba womuntu is umahluko kusuka izicubu embryonic - mesenchyme. Ngo inqubo lolu shintsho kwakhiwa kwezitho nezicubu zomzimba, okuyinto akheke nenjongo ehlukene. Ngu ohlelweni zezinzwa zihlanganisa imisipha bushelelezi, zezinzwa aminyene futhi okuxekethile uqwanga izicubu, uketshezi lomzimba, isimiso semithambo yegazi.

izicubu Okuxekethile zezinzwa yakha capsule kwezitho nezicubu. Izinhlaka eziyinhloko zezinzwa izicubu amaseli, amorphous futhi izakhiwo fibrous. Isakhiwo amaseli nemisebenzi yabo zahlukahlukene kakhulu. Amaphesenti eziyinhloko fibroblasts, okuyinto iqhaza kumiswa amaprotheni, eyandulela collagen, mucopolysaccharides. Kukhona nezinye izinhlobo fibroblasts ezihilelekile ekwakhekeni kwezitho nezicubu. It osteoblasts, chondroblasts, nabanye. Uhlelo ezicutshini iqukethe ama-macrophage, ehilelekile impendulo ukuvuvukala nezicubu ukulungisa, omzimba ukusabela ekulweni izifo ezibangelwa amagciwane kanye ezibangelwa amagciwane. amaseli Mast kukhona ezicutshini kwakhiwa obuningi phakathi ukuvuvukala, secrete balamuli (histamine, njll).

The main isithako - isisekelo esihlanganisa amaseli ayo yemisipha. Siqukethe proteoglycans, polysaccharides namaprotheni. ngamaketanga Proteoglycan aqukethe asidi i-hyaluronic, heparin, chondroitin sulfate. Hyaluronan inquma ulwelwesi permeability izindwangu. izakhiwo fibrous aqukethe enwebekayo Imicu yotshani kuyi-collagen.

imisebenzi
ezicutshini eqala umsebenzi asekelayo, njengoba kuyintando ngesisekelo amathambo, isikhumba kanye nezinhlaka we stroma. Indwangu buyimfanelo enamandla okusezingeni eliphezulu futhi kuyaqina ngesikhathi esifanayo, sibonga oyiyo fibrous.
umsebenzi trophic kwezicubu kungenxa entry lwalo igazi, lymph zomzimba. Proteoglycans zinengxenye amanzi exchange futhi izinqubo umzimba emzimbeni.

Umsebenzi ayisivikelo ezicutshini bunikezwa isikhumba, ulwelwesi kanye izitho zangaphakathi amaphilisi. umsebenzi reparative ukushabalalisa ikhono zezinzwa umonakalo asesibelethweni ukuhlukumezeka, ukusabela ukuvuvukala.

Zezinzwa izicubu isifo
Ngesisekelo zezinzwa izicubu isifo kuyinto ukuthuthukiswa inqubo sokugembula kule izicubu ngokwayo noma izithako zawo. Njengoba iyingxenye izitho eziningi nezicubu, izifo zalo angaqoqwa. Izifo kuhlangene ku isimiso etiological futhi pathogenetic okufana ngaso ukubonakaliswa emtholampilo.

Iqembu sokuqala rheumatism. Isigaba sesibili sihlanganisa isifo ehlasela umzimba (lupus, scleroderma, Sjögren Syndrome, letindzala zezinzwa izicubu isifo). Iqembu lesithathu - a vasculitis letindzala. iqembu Okwesine - rheumatoid arthritis, samathambo engamahlongandlebe. Kulandele: spondylitis ankylosing, isifo sokuqaqamba kwamalunga ezithathelwanayo ne-osteoarthritis.

Izimbangela yezifo ezicutshini
Ngo isifo ngasinye has izici zayo siqu etiological. Kodwa izimbangela ezivamile okuvela ezicutshini yilezi: igciwane strep, isifo sofuba Mycobacterium, agent causative of isipatsholo nogcunsula, Umkhuhlane amagciwane, isimungumungwane. Asikabi yofuzo e okuvela izifo letindzala. Isici okuholela okuvela kwezinso kukhona amaphutha amasosha omzimba. umonakalo Tissue kubangelwa sebethule izakhiwo mzimba kwakhiwa ngenxa omzimba ephendula ukuchayeka ejenti etiologic.

ukubonakaliswa emitholampilo
Ukuze isifo ngasinye ethize libhekene zako zokwelapha, kodwa kukhona ezijayelekileko. Kuyinto Yebo intuthuko futhi eside lesi sifo, inkathi febrile, isifo ngokuhlanganyela, ukuncipha emzibeni, iguliswa like ukusabela, izinguquko igazi amaprotheni amafraktjhini, ukunqotshwa esikhumbeni, yi emihle kusukela ukusetshenziswa kwezidakamizwa hormone.
