I-nuchal lymph nodes yimizimba eyenza umsebenzi wefayile. Kuye kudlulela i-lymph evela kuzo zonke iinxalenye zomzimba. Kulapha ukuba iziganeko zangaphandle ezitholakale emzimbeni zichongiwe. Emva koko, i-immune system isabela kwisiphumo. Kwizikhundla kukho ukuphindaphinda kweeseli ezikhethekileyo ezihlasela amaprotheni angaphandle, ngaloo ndlela zikhusela umzimba.
Imisebenzi ephambili
Ama-lymph nodes atholakala kuwo wonke umzimba. Phakathi kwabo badibaniswe yinkqubo enye, apho umlambo uhamba khona. Ngexesha lokusebenza komsebenzi walo oyintloko, nayiphi na i-lymph node inokwandisa ubungakanani - oku kwenzekayo xa usulelo lungena emzimbeni, nokuba ngaba ibhakteria, i-parasitic, i-viral okanye nayiphi na enye. Zizo zimbutho ezigcina ama-microorganisms ngendlela engafanelekanga kumzimba womntu.
Ukuvuvukala kwe-node ye-occipital kuthiwa yi-lymphadenitis, kwaye ukuvuvukala kuthiwa yi-lymphadenopathy. Kubantwana, iingxaki zeentlanzi ziqheleke ngakumbi kunabantu abadala. Oku kungenxa yokuphuhliswa kwe-immune system, engenako ngokwaneleyo ukumelana nokusuleleka. Inkqubo eyinkqubo yokusuleleka iyinkimbinkimbi kakhulu, ikhudlwana ubukhulu beendawo kunye neentlungu ezingaphezulu.
Izizathu zokuvuvukala i-lymph nodes
I-Lymphadenitis ihlukaniswe ngo: ayikho into ecacileyo kunye neyodwa. Okukugqibela kuyimpawu zezifo ezinzulu ezifana:
- isifo sofuba;
- imasisi;
- AIDS;
- mononucleosis .
Ukongezelela, intlungu e-occipital lymph nodes ingabonisa i-rheumatoid arthritis okanye i-leukemia.
Uhlobo olungapheliyo lwe-lymphadenitis luvame ukuxilongwa xa kugxininiswa kokuvuvukala kufutshane neentlanzi. Ngokuqhelekileyo imbangela yilezi zifo ezingapheliyo:
- ziqeshwe;
- i-phlegmon;
- i-angina ne- pharyngitis engapheliyo ;
- i-trophic ulcer;
- Otitis.
Ukuxilongwa kwezilwanyana
Ukuba ngokukhawuleza kwacaca ukuba i-occipital okanye nayiphi na i-lymph node yanda, kufuneka wenze i-aphoyintimenti kunye neengcali ngokukhawuleza. Ukuba iimpawu azidluli okanye ziqhubeke zibi kakhulu, kwaye ngaphezu koko kukho ukuphazamiseka komzimba, kungcono ukubuyela kwi-ambulensi. Ukuphuhliswa okukhawulezileyo kwesi sifo kuthetha kuphela ukuba iingxaki zingenzeka kwixesha elizayo, i-meningitis iqala.
Naluphi na ukuxilongwa luqala ngokuhlolwa kwangaphandle, okwenziwa ngugqirha ofanelekileyo. Ukuba akukho nto ingenakukwazi ukucacisa eso sifo ngeempawu zangaphandle, ngoko kungcono ukwenza uhlalutyo lwezinto.
