I-corona radiata iyimfumba yamagqabhagqabha enesibindi ekhona kwingqondo. Ngokukodwa, iiservices ze-corona radiata zithatha ulwazi phakathi kweeseli zengqondo ze-cortex yecerebral kunye neeseli zengqondo ebuchosheni.
I-cortex ye-cerebral yindawo yengqondo ejongene nokucwangcisa ulwazi oluqapheleyo, ngelixa ubuchopho buba buxhamli phakathi kwentambo yomgogodla kunye nengqondo.
Ingqondo ihamba kunye ne-cortex yecerebral ibandakanyeka kwi-sensation kunye ne-motor function, kwaye i-corona radiata idibanisa zombini imoto kunye neendlela zentliziyo eziphakathi kwezi zakhiwo.
I-Corona Radiata Ingaba
I-corona radiata ibalulekileyo iqela leentsholongwane ngenxa yendima yalo ekuthumeni nasekufumaneni imilayezo phakathi kwemimandla yengqondo. Iiseli zesibindi ze-corona radiata zichazwe njengezidibanisa kunye ezichanekileyo. Oku kuthetha ukuba bathatha imilayezo eya kunye nomzimba. Igama elithi 'inxulumene' libhekiselele kwingongoma yecala kunye nezinye igalelo ezithunyelwe emzimbeni ukuya kwingqondo, ngelixa igama elithi 'efferent' libhekisela kwimilayezo ethunyelwe ukusuka kwingqondo ukuya emzimbeni ukulawula umsebenzi weemoto I-corona radiata yenziwe ngamabini kunye nemibhobho eqhelekileyo edibanisa i-cortex ye-cerebral kunye nengqondo.
I-Corona Radiata Ukulimala kunye neStroke
I-corona radiata inokulimazwa ngengozi ebandakanya amagatsha amancinci emithambo yegazi.
Izibetho ezichaphazela i-corona radiata zibizwa ngokuba yimivimbo engama-subcortical , i-lacunar, izibetho ezincinane okanye iimpahia ezimhlophe.
Isizathu sokuba lo mmandla uchazwa njengombala omhlophe kukuba 'kakhulu i-myelinated', oku kuthetha ukuba ukhuselwe luhlobo olukhethekileyo lweethambo ezinamafutha ezikhusela kwaye zikhusela iisensi zeentsimbi.
Ikwachazwa nje ngokuba yi-subcortical kuba itholakala kwingingqi ephantsi kwengqungquthela yengqondo. Kwaye i-corona radiata i-stroke ichazwa ngokuthi 'i-lacunar stroke' okanye 'i-stroke encinci', kuba i-corona radiata ifumana ukunikezelwa kwegazi kumasebe amancinci emithambo engqondweni.
Abantu abachaphazelekayo ngemivimbo emincinci encinane kwi-corona radiata okanye kwenye indawo kwingqondo bavame ukuchazwa njengento ene- cerebrovascular disease, eyimeko ebonakaliswe yimida emancinci, i-blood clot i-blood circulation streaked in brain and strokes. Izibetho ezibandakanya i-corona radiata inokuba yincinci, kwaye ingabangela iimpawu. Izibetho ezinjalo zibizwa ngokuba yi- strokes .
Ngakolunye uhlangothi, i-stroke echaphazela i-corona radiata inokuvelisa iimpawu ezingezizo ezinjengokungakwazi ukuzinyamekela, oko kukuthi ulungelelaniso lwe-stroke , nangona kungekho zibonakaliso ezinkulu ze-stroke kwi-MRI yengqondo okanye kwi-Brain CT scan .
Ezinye iiNgxaki zeZonyango zingenza iRadio
Ngaphandle kwesifo, kukho ezinye izimbangela zokulimala kwi-corona radiata. Ezi ziquka izicubu zeengqondo, ukusasazeka komhlaza emzimbeni (i-metastasis), intlungu yesifo, ukuphuma kumbilini kunye nokusuleleka kwengqondo. Naliphi na le miqathango inokuchaphazela umsebenzi we-corona radiata.
Ukubaluleka kwe-Corona Radiata
Okuthakazelisayo kukuba, uphando olutshanje luye lwabonisa indima entsha ye-corona radiata ekuqikeleleni isiphumo sokuphazamiseka. Iingcali zenzululwazi zihlolisise imetabolism yemimandla eyahlukeneyo yengqondo emfutshane emva kokuphazamiseka, usebenzisa ubuchule bokucabangela ubugcisa. Emva kokuvavanya ukuhlaziywa kwesifo segulane, kwavela ukuba umsebenzi we-corona radiata ngaphakathi kweeyure ezingama-24 zokuqala emva kokuba u-stroke uqhathaniswe nokuqatshelwa kwesiphumo emva kokuphazamiseka.
ILizwi
Ukukhusela i-corona radiata isifo esikuyo kulwa nokukhuselwa kwesifo. Uthintelo lwe-Stroke lusekelwe kwizinto ezibalulekileyo ezibalulekileyo: iindlela zokuphila kwangexesha elide kunye nokunakekelwa kwezempilo rhoqo.
Ukutshaya kuyingozi enkulu yokuphazamiseka, ngoko ukuyeka ukutshaya kuyinto ebalulekileyo yokuthintela isifo. Ukutya ukutya okunempilo kunye nokuzivocavoca rhoqo kuyenzizinto zokukhusela isifo. Ingcinezelo yinto enye yokuphila engabangela ingozi yokuphazamiseka. Ukwenza imizamo yokuphucula nokunciphisa ingcinezelo kuye kwaboniswa ukunceda ukukhusela isifo.
Ukongeza, ukujongana nemiba yezokwelapha ezifana ne-cholesterol ephakamileyo kunye nokunyuswa kwengcinezelo yegazi kunokuncedisa ukunciphisa umngcipheko we-stroke. Xa kufikelele ekukhuselweni kwesithintelo, kubalulekile ukuba uhlolisise rhoqo ugqirha wakho, kuba iinkalo eziliqela zokuhlola rhoqo kwizonyango zenzelwe ukufumanisa ingozi ye-stroke.
