I-corona radiata iyisigxobo sezinzwa zomzimba ezisebuchosheni. Ngokuqondile, izinzwa ze-corona radiata zithwala ulwazi phakathi kwamaseli obuchopho be-cerebral cortex kanye namaseli obuchopho ebuchosheni.
I-cortex ye-cerebral yindawo yengqondo ephethe ukucubungula ulwazi oluqaphelayo, kuyilapho ubuchopho buba khona ukuxhumana phakathi komgogodla nobuchopho.
Ubuchopho buqala kanye ne-cortex ye-cerebral kokubili kuhileleke ekuzwayo kanye nemishini yokusebenza, futhi i-corona radiata ixhuma kokubili imigudu yezinzwa nezinzwa eziphakathi kwalezi zakhiwo.
Okushiwo yi-Corona Radiata
I-corona radiata yiqembu elibalulekile lezinzwa ngenxa yendima yalo ekuthumeni nasekutholeni imiyalezo phakathi kwezifunda ebuchosheni. Amaseli ayisisindo e-corona radiata achazwa njengama-afferent and efferent. Lokhu kusho ukuthi bathatha imilayezo eya nasemzimbeni. Igama elithi 'lihlukile' libhekisela ekufakweni kwezinzwa nokunye okuthunyelwe okuvela emzimbeni kuya ebuchosheni, kanti igama elithi 'efferent' libhekisela kwimilayezo ethunyelwe ebuchosheni eya emzimbeni ukulawula umsebenzi umsebenzi I-corona radiata yenziwe kokubili okuthandanayo kanye nemicu eqondile ehlanganisa i-cortex ye-cerebral kanye nobuchopho.
Ukulimala kweCorona Radiata kanye nesifo sohlangothi
I-corona radiata ingalimazwa yi-stroke ehlanganisa amagatsha amancane emithini yegazi.
Izibhamu ezithinta i-corona radiata ngokuvamile zibizwa ngokuthi ama- subcortical strokes , ama-lacunar, ama-strokes amancane noma ama-white strokes.
Isizathu sokuthi lesi sifundazwe sichazwa njengombala omhlophe ukuthi 'kakhulu i-myelinated,' okusho ukuthi ivikelwe uhlobo oluthile lwezicubu ezinamafutha ezivikela futhi zivikela amangqamuzana omzimba.
Ibuye ichazwe njenge-subcortical ngoba itholakala esifundeni esijulile esingaphansi kwe-brain. Futhi ukushaywa kwe-corona radiata kuchazwa ngokuthi 'i-lacunar stroke' noma 'isisindo esincane semikhumbi' ngoba i-corona radiata ithola igazi elivela emagatsheni amancane emithanjeni ebuchosheni.
Abantu ababhekene nezinhlangothi eziningana ezincane emgodini we-corona noma kwenye indawo ebuchosheni bavame ukuchazwa ngokuthi banezifo eziyingozi, okuyisimo esibonakala ngemithambo encane, egazini legazi elibhekene negazi elibhekene nobuchopho kanye nemivimbo emincane. Imivimbo ehlanganisa i-corona radiata ingahle ibe yincane, futhi ingase ingabangeli izimpawu. Izibhamu ezinjalo zivame ukubizwa ngokuthi izigubhu zomsindo .
Ngakolunye uhlangothi, ukushaywa komzimba okubandakanya i-corona radiata kungaveza izimpawu ezingenasici ezifana nokuhluleka ukuzikhathalela, okuyinto yokuqeda isifo , ngisho noma kungekho zibonakaliso ezinkulu zokushaywa komzimba ku-MRI ebuchosheni noma ku-Brain CT scan .
Ezinye izinkinga zemithi zingathinta i-Corona Radiata
Ngaphandle kwesifo, kunezinye izimbangela zokulimala kwi-corona radiata. Lezi zihlanganisa izicubu zobuchopho, ukusakazeka komdlavuza emzimbeni (imetastasis), ikhanda lokulimala, ukuphuma kwegazi ebuchosheni kanye nokutheleleka kobuchopho. Noma yimuphi wale mibandela ingathinta umsebenzi we-corona radiata.
Ukubaluleka kwe-Corona Radiata
Ngokuthakazelisayo, ukuhlolwa kwamuva kuye kwaveza indima entsha ye-corona radiata ekubikezelweni komphumela wesifo. Ososayensi bahlola ukuxubha kwemvelo ezindaweni ezihlukahlukene zobufushane bobuchopho ngemva kokushaywa yisisu, besebenzisa amasu okucabangela ama-sophisticated. Ngemva kokuhlola ukutholakala kwesifo sogulane, kwenzeka ukuthi umsebenzi we-corona radiata ngaphakathi kwamahora angu-24 okuqala ngemva kokushaywa kwesisu kwaqondana nomphumela ngemuva kokushaywa yisifo.
Izwi kusuka
Ukuvimbela i-corona radiata isifo sokuvimbela isifo sokuvimbela isifo. Ukuvimbela isisu kusekelwe ezintweni ezimbili eziyinhloko ezibalulekile: imikhuba yokuphila isikhathi eside nokunakekelwa kwezempilo njalo.
Ukubhema kuyingozi enkulu yokushaya isifo, ngakho ukuyeka ukubhema kuyingxenye ebalulekile yokuvimbela ukushaywa yisifo. Ukudla ukudla okunempilo nokuzivocavoca njalo nakho kuyisici sokuvimbela ukushaywa yisifo. Ukucindezeleka kungenye inkinga yokuphila engabangela ingozi yokuphazamiseka. Ukwenza imizamo yokuphumula nokunciphisa ukucindezeleka kuye kwaboniswa ukusiza ukuvimbela isifo.
Ngaphezu kwalokho, ukubhekana nezinkinga zezokwelapha ezifana ne-cholesterol ephezulu kanye nokucindezelwa kwegazi kungasiza ukunciphisa ingozi yokushaywa yisifo. Uma kuziwa ekuvimbeleni ukushaywa yisisu, kubalulekile ukugcina uhlolwe njalo nodokotela wakho, ngoba izici eziningana zesheke sakho sezokwelapha zijwayele ukukhomba ubungozi bokuhlaselwa.
