Ama-sutures we-Cranial

Ama-suture we-Cranial yizintambo zezicubu ezixhuma amathambo ogebhezi.

Ukhakhayi lwengane lwakhiwa ngamathambo e-cranial (skull) ahlukene ayisithupha:

• Ithambo langaphambili
• Ithambo le-Occipital
• Amathambo amabili weparietali
• Amathambo amabili wesikhashana

La mathambo abanjwa ndawonye ngezicubu eziqinile, ezinemicu, ezinwebeka ezibizwa ngokuthi ama-sutures.

Izikhala eziphakathi kwamathambo ezihlala zivulekile ezinganeni nasezinganeni ezincane zibizwa ngama-fontanelles. Kwesinye isikhathi, zibizwa ngamabala athambile. Lezi zikhala ziyingxenye yentuthuko ejwayelekile. Amathambo e-cranial ahlala ahlukile izinyanga eziyishumi nambili kuya kwezingu-18. Bese zikhula ndawonye njengengxenye yokukhula okujwayelekile. Bahlala bexhumekile phakathi nokuba ngabantu abadala.

Ama-fontanelles amabili imvamisa akhona kugebhezi lomntwana osanda kuzalwa:

• Phezulu kwekhanda eliphakathi nendawo, phambili nje kwesikhungo (anterior fontanelle)
• Ngemuva maphakathi kwekhanda (posterior fontanelle)

I-fontanelle yangemuva imvamisa ivalwa ngeminyaka eyi-1 noma engu-2 yobudala. Kungenzeka ukuthi isivele ivaliwe lapho izalwa.

I-fontanelle yangaphakathi ivame ukuvala isikhathi esithile phakathi kwezinyanga eziyi-9 nezinyanga eziyi-18.

Ama-suture nama-fontanelles ayadingeka ekukhuleni kwengqondo nasenganeni ukukhula. Ngesikhathi sokubeletha, ukuguquguquka kwama-suture kuvumela amathambo ukuthi agudlane ukuze ikhanda lengane lidlule emseleni wokuzalwa ngaphandle kokucindezela nokulimaza ubuchopho bawo.

Ngesikhathi sobuntwana nasebuntwaneni, ama-suture ayaguquguquka. Lokhu kuvumela ubuchopho ukuthi bukhule masinyane futhi kuvikele ubuchopho emiphumeleni emincane ekhanda (njengalapho usana lufunda ukubamba ikhanda lalo, liginqike, futhi luhlale phansi). Ngaphandle kwemisipha nezintambo eziguquguqukayo, ubuchopho bengane abukwazanga ukukhula ngokwanele. Ingane ingaqala ukulimala ebuchosheni.

Ukuzwa ama-cranial sutures nama-fontanelles kungenye yezindlela abahlinzeki bezokunakekelwa kwempilo abalandela ngayo ukukhula nokukhula kwengane. Bayakwazi ukuhlola ingcindezi ngaphakathi kobuchopho ngokuzwa ukungezwani kwama-fontanelles. Ama-fontanelles kufanele azizwe eyisicaba futhi aqine. Ama-fontanelles aqhamukayo angaba uphawu lokucindezela okwandayo ngaphakathi kobuchopho. Kulokhu, abahlinzeki bangadinga ukusebenzisa amasu we-imaging ukubona ukwakheka kobuchopho, njenge-CT scan noma i-MRI scan. Kungadingeka ukwelashwa ukuze unciphise ingcindezi eyandayo.

Ama-fontanelles adangele, acindezelekile kwesinye isikhathi aluphawu lokwehla emzimbeni.
