Yiziphi ulwelwesi ingqondo

Ubuchopho bomuntu iyingxenye ohlelweni sezinzwa, esakhiwa inqwaba izinqubo ezihlobene of amangqamuzana ezinzwa futhi unesibopho zonke imisebenzi yomzimba. umnyango ingaphakathi Cranial, equkethe medulla, ukuvikela amathambo zangaphandle amathonya lokukhanda. Ubuchopho, kanye nomgogodla, imbozwe ulwelwesi ezintathu: kanzima, soft futhi arachnoid, ngamunye okhona njengamanje owenza umsebenzi walo.

Ukwakheka Dura

Luhlala Isikhathi Eside okuqinile igobolondo ingqondo kuyisimo periosteum obukhulu cranial, okuyinto has a obuqinile. Ebusweni engaphakathi igobolondo has ezihlobene eziningana ukungena ezijulile ebuchosheni umqhewu eminyangweni ehlukene. Umhlangano omkhulu kunayo yonke inqubo enjalo itholakala phakathi ama- amabili, okubonisa ukufana isikela posterior kwesigaba okuyinto okuhlanganisiwe ne snaring cerebellum futhi kuvimbela it kusukela iyizingxenye occipital. Phezu ulwelwesi aminyene ubuchopho, kukhona enye inqubo ukuthi ibekwe emhlabeni lo turcica sella, ukwakha uhlobo beso nokunikeza ukuvikelwa pituitary ngokweqile ubuchopho mass ingcindezi. Ngezinye izingxenye abafanele kukhona sinuses okhethekileyo, obizwa ngokuthi sinusitis, okuyinto eyenzeka Reflux emithambo yegazi.

Isakhiwo arachnoid ikhanda nobuchopho

Arachnoid ubuchopho igobolondo esisogwini ngaphakathi igobolondo kanzima. Nakuba ayehlala mncane kakhulu futhi esobala, kodwa akusho ukungena imifantu futhi Grooves ama- ngesikhathi esifanayo esehlanganise bonke ubuso ketshezi ebuchosheni, futhi ezihamba ngezinyawo besuka kwenye ingxenye kwelinye. Kusukela cerebrovascular ulwelwesi arachnoid ehlukanisa isikhala subarachnoid, okuyinto ugcwele cerebrospinal fluid. Lapho igobolondo itholakala kwi anemifantu ejulile nebanzi, isikhala subarachnoid liya livuleka njengoba zikhula, ukwakha ezihlukahlukene ithangi osayizi. Ngenhla izingxenye convex, ikakhulu ngaphezu convolutions, ulwelwesi ithambe futhi arachnoid zobuchopho eduze bezama nomunye, ngakho isikhala subarachnoid kulezi zindawo ayisesemikhulu kakhulu futhi igebe capillary.

Amagama imithombo emikhulu subarachnoid:

• itheku cerebellar-cerebral itholakala inkatho phakathi cerebellum futhi indawo lapho itholakala the oblongata medulla ;
• izimbobo itheku lateral elise ohlangothini engezansi ama- cerebral;
• chiasm tank isebenza ikhanda basal, ne phambi chiasm optic;
• Kwasendaweni ithangi interpeduncular - phakathi kwemilenze ebuchosheni fossa interpeduncular.

ulwelwesi lwesisu, kwenze ingqondo kuyizinto zezinzwa izakhiwo izicubu, nakho amboze asebuchosheni nomgogodla. Zenza umsebenzi Ukuvikelwa, ukudala gistogematicheskie, likvorogematichesky likvorotkanevy Imigoqo ezihambelana umzimba futhi outflow lomcebo cerebrospinal. Ngaphandle kwalezi izakhiwo akukwazi ukusebenza evamile zobuchopho futhi eyanele zonke izinto zakhe ezibalulekile.
