I-ventricles yobuchopho yimijondolo emine engaphakathi kobuchopho equkethe ubuchopho bomgogodla (CSF) . Kunezinhlobo ezimbili ze-lateral ventricles- eyodwa ohlangothini ngalunye lwe-cortex ye-cerebral. I-ventricles lateral iyaqhubeka ne-ventricle yesithathu, ephansi ebuchosheni. I-ventricle yesithathu iyaqhubeka ne-ventricle yesine, egijima ku-brainstem.
I-ventricles yonke ingxenye ebalulekile ye-"system system". Ama-ventricles ahlangene nomunye nomunye, futhi futhi nomsele ongaphakathi womgogodla kanye nesikhala esingaphansi komhlaba (isikhala esiphakathi kwezixhumanisi ezimbili ezihlukanisa ubuchopho kusuka i-skull). I-CSF ikhiqizwa yi-lining of ventricles. I-CSF ibuye ijikeleze kulo lonke uhlelo lwe-ventricular futhi ekugcineni liphinde lifakwe kabusha esikhaleni esinqunyiwe.
Okubalulekile
Uhlelo lwe-ventricular lubaluleke kakhulu ekusebenzeni okuvamile kwesistimu yezinzwa zomphakathi. Ivikela ubuchopho ngokuyivumela ukuba "iqhubekele" ekugezeni okuketshezi futhi inikeze isithakazelo sokwethuka ngokumelene nokuhlukunyezwa kwekhanda. I-CSF ngokwayo iyasiza futhi ukuhlinzeka izakhi emcimbini futhi igcine ubuchopho ngokulinganisela kwamakhemikhali.
Izinkinga ezingenzeka
Ukuvimbela ukugeleza kwe-CSF kubangela ukuthi ingcindezi ikhuphuke ngaphakathi kwesimiso se-ventricular futhi ingaveza i-hydrocephalus.
Ukutheleleka (njengokuthi i- meningitis ) noma ukuphuma kwegazi kungashintsha izici ze-CSF. Ukukhishwa kwe-lumbar (LP), okubizwa nangokuthi umgogodla womgogodla, kungasetshenziswa ukukala ukucindezela ngaphakathi komgogodla womgogodla, nokuhlola i-CSF ngezibonakaliso zokutheleleka, ukuvuvukala, noma ukulimaza.
I-LP ivame ukubaluleka ekuhloleni izifo zesimiso sezinzwa eziphakathi.
Isibonelo, ekuqhumeni kwe- subarachnoid , i-CT scan ingaba yinto evamile, kodwa i-LP izoveza igazi kwi-CSF.
