Ngaba wakha wacinga ngendlela ingqondo yethu eyinkimbinkimbi neyilwe ngayo ngokumangalisayo? Ukuze ingqondo isebenze kakuhle, idinga igazi elicocekileyo neligcwele ioksijini rhoqo. Ngoko ke ukuze yenze lo msebenzi ngokufanelekileyo, ingqondo inenkqubo yokhuseleko emangalisayo. Ifana nesangqa esikhulu esiphakathi kwesixeko, esikunceda ukuba uthathe enye indlela ukuba kukho ukuxinana kweemoto. Namhlanje sithetha ngale nkqubo yokhuseleko emangalisayo.
Yintoni iCircle of Willis?
Ngamafutshane,
iCircle of Willis (CoW) sisakhiwo esifana nesangqa esenziwe yimithambo yegazi
(imithambo yegazi) ekwisiseko sobuchopho bethu, oko kukuthi, ezantsi. Inesimo esifana nepentagram. Le yindlela edibanisa imithambo yegazi emibini ephambili ehambisa igazi ebuchotsheni bethu. Khawuthelekelele ukuba kukho imithambo yegazi emibini ephambili ehambisa igazi ebuchotsheni bethu. 1.
I-Internal Carotid Artery: Le yindlela ehambisa uninzi lwegazi ngaphambili kobuchopho. 2.
I-Vertebral Artery: Le yindlela ehambisa igazi ngasemva kobuchopho. Ngoko ke, zombini ezi mithambo yegazi zidibana kwindawo ejikelezayo ebizwa ngokuba yiCircle of Willis. Ngenxa yoku, ukuba kukho naluphi na uthintelo okanye ukuvaleka komthambo omnye, igazi lingathunyelwa kwindawo efunekayo ngenye imithambo yegazi. Oku kufana nenkqubo yendalo 'ekhuselekileyo' yokhuseleko lobuchopho bethu. Ibizwa ngokuba yi "Ring of Willis" ukuhlonipha isazi se-anatomist uThomas Willis, owafumanisa okuninzi malunga nesi sakhiwo simangalisayo.
Ngaba wonke umntu unalo eli ring?
Nantsi into emangalisayo. Ngokutsho kwabaphandi, ngaphantsi kwesiqingatha sabantu abanalo
indandatho epheleleyo yeWillis . Oko kuthetha ukuba uninzi lwabantu lunokuba notshintsho oluncinci, okanye ukungafezeki, kule ndandatho. Utshintsho olunjalo luzalwa nalo. Olu lutshintsho lwendalo olwenzeka xa imithambo yegazi yethu isenziwa esibelekweni. Oku akusisifo okanye isiphene.
Ukuba nendandatho kaWillis engaphelelanga akuthethi ukuba uyagula. Abantu abaninzi baphila ubomi obusempilweni xa benendandatho kaWillis engaphelelanga.
Kodwa, nantsi into. Ukuba umntu one-annulus engaphelelanga unemeko enxulumene nemithambo yegazi engqondweni, efana ne
- stroke , iziphumo zinokuba nkulu kancinci. Kuba loo 'ndlela eyahlukileyo' okanye 'indlela ephambukayo' esithethe ngayo ayisebenzi kakuhle. Le asiyonto esinokuyitshintsha, yile ndlela umzimba wethu owakhiwe ngayo.
Iyintoni intsingiselo yokwenyani yeRing of Willis?
Eyona ndlela ilungileyo yokuyiqonda le nto kukuchaza ngakumbi ngomzekelo wendlela ejikelezileyo esikhankanyileyo ngaphambili. Khawucinge nge-roundabout enkulu efana nale ikwiHolo yeDolophu yaseColombo. Idibanisa iindlela ezininzi ezinkulu. Ngoku khawucinge ukuba kukho ingozi enkulu kwenye yeendlela ezinkulu kwaye indlela ivaliwe ngokupheleleyo. Kwenzeka ntoni ke? Izithuthi ezivela kwezinye iindlela zingasebenzisa le roundabout, zidlule kwindlela evaliweyo zize zifike apho ziya khona. I-Ring of Willis yenza
kanye oku . Ukuba umthambo wegazi omkhulu othwala igazi ebuchotsheni uvaliwe okanye wonakele, ukuba kukho i-Ring of Willis epheleleyo, igazi elivela kwelinye icala lingadlula kule ring lize linike igazi kwinxalenye yengqondo ephulukene negazi. Oku kuthintela umonakalo omkhulu kwiimeko ezininzi. Ukuba ne-Ring of Willis epheleleyo kunokukukhusela kwimiphumo emibi yeemeko ezilandelayo:
| Imeko yezonyango | Ukhuseleko olubonelelwa yiRing of Willis |
|---|
| Istroke | Nokuba umthambo wegazi uvalekile, igazi liyajikiswa ngenye indlela, nto leyo enciphisa umonakalo engqondweni. |
| Ukuqhuma kwe -aneurysm yobuchopho | Inceda ukugcina igazi lihamba kwiindawo ezijikeleze umthambo owonakeleyo. |
| Ukufakwa kwamafutha kwimithambo yegazi (i-atherosclerosis) | Njengoko umthambo uncipha kancinci kancinci, ukuhamba kwegazi kwezinye izitho kuyanda ukuze kulungiswe loo ngxaki. |
| Isifo seCarotid Artery | Nokuba umthambo omkhulu entanyeni uvalekile, oko kunceda ukugcina igazi lihamba engqondweni. |
Ngawaphi amathuba okuba ugqirha akuxelele ngale nto?
Ngokwesiqhelo, uninzi lwabantu alusoze lukwazi ukuba lune-ring kaWillis de kufunyaniswe ukuba lunesifo. Nangona kunjalo, kwezinye iimeko, ugqirha wakho unokukuxelela ngayo.
- Ukuba une - brain aneurysm : Malunga ne-85% yee-brain aneurysms zenzeka kwiRing of Willis.
- Ukuba unestroke : Istroke inokubangelwa kukuvaleka okanye ukopha emthanjeni wegazi kwiRingi yeWillis.
- Ukuba unesifo sikaMoyamoya: Esi sisifo esingaqhelekanga kakhulu esibangela ukuba imithambo yegazi ekwiRingi yeWillis inciphe kancinci kancinci ize ivaleke.
- Ukuba kufuneka utyando olusezantsi kwengqondo: Umzekelo, xa usenza utyando kwi-aneurysm okanye i-pituitary gland tumor, kubaluleke kakhulu ukuphepha ukonakalisa iringi kaWillis.
- Ukuba une -brain scan : Ukuba une-exam ekhethekileyo, efana ne -MRI yengqondo okanye i-cerebral angiogram, ingxelo ingabandakanya ulwazi malunga nohlobo lwe-Ring of Willis yakho.
Yintoni esifanele siyenze ukuze sigcine iRing of Willis isempilweni?
Njengoko besitshilo ngaphambili, asinakutshintsha ulwakhiwo lweRing of Willis. Yinto ekhoyo xa umntu ezalwa. Nangona kunjalo, zininzi izinto esinokuzenza ukugcina imithambo yegazi engaphakathi kuloo ring iphilile kwaye ingenazithintelo. Ngamafutshane,
kufuneka silawule izinto ezinobungozi ezonakalisa imithambo yegazi engqondweni. Makhe sijonge ukuba zeziphi ezi zinto zinobungozi. Ukulawula ezi zinto akulunganga kwiRing of Willis yakho kuphela, kodwa nakumzimba wakho wonke, ngakumbi intliziyo yakho.
| Into enobungozi | Kwenziwe ntoni |
|---|
| Igazi elonyukayo | Sebenzisa amayeza kanye njengoko ugqirha ewayalele. Nciphisa ukutya ityuwa. Zilolonge. |
| I-Cholesterol ephezulu | Nciphisa ioyile, ukutya okuqhotsiweyo, kunye nokutya okukhawulezayo. Yitya imifuno, iziqhamo, kunye nemifuno eluhlaza ngakumbi. |
| Isifo seswekile | Gcina amanqanaba eswekile egazini lakho ephantsi kolawulo. Landela ukutya kwakho kunye neengcebiso zonyango. |
| Ukutshaya | Yeka ukutshaya ngokupheleleyo. Oku kubangela umonakalo omkhulu kwimithambo yegazi. |
| Ukutyeba kakhulu | Lawula ubunzima bomzimba wakho ngokutya ukutya okufanelekileyo kunye nokuzilolonga rhoqo. |
| Ukusetyenziswa kotywala | Kuphephe ukusela utywala kakhulu. |
Eyona nto ingcono onokuyenza kukuthetha nogqirha wakho wosapho ngale micimbi uze ulungise indlela ophila ngayo ukuze ihambelane nawe.
Umyalezo Wokuya Ekhaya
- I-Circle of Willis yiringi ekhuselayo ezantsi kwengqondo eyenziwe yingqokelela yemithambo yegazi ehambisa igazi engqondweni.
- Umsebenzi wayo ophambili kukunciphisa umonakalo engqondweni ngokujika igazi liye kwenye indlela ukuba omnye wemithambo yegazi ethwala igazi liye engqondweni uyavaleka.
- Asinguye wonke umntu oneringi 'egqibeleleyo'. Uninzi lwabantu lunezahluko ezincinci. Ayisosifo, kodwa yimeko yendalo ephuma ekuzalweni.
- Nangona singenakuyitshintsha imilo yale ring, singayigcina le mithambo yegazi isempilweni ngokulawula uxinzelelo lwegazi, i-cholesterol, isifo seswekile , nokuphepha ukutshaya.
- Ukuba uvavanywa ingqondo okanye uthetha ngemeko ethile yempilo, ukuba ugqirha uyakukhankanya oku, ungoyiki ukubuza uze ufumane impendulo. Unelungelo lokwazi ngomzimba wakho.
Isangqa sikaWillis, ukunikezelwa kwegazi ebuchotsheni, isifo sohlangothi, i-aneurysm yobuchopho, imithambo yegazi ebuchotsheni, ulwakhiwo lobuchopho, i-anatomy ngesiSinhala
