Ukubuka konke

Ubuchopho buqukethe izinzwa ezingaphezu kwezigidi eziyizinkulungwane eziyinkulungwane. Amaqembu athile awo, asebenza ekhonsathini, asinikeza amandla okucabanga, ukuzwa imizwa, nokuqonda umhlaba. Futhi zisinika amandla okukhumbula izingcezu eziningi zolwazi.

Kunezinto ezintathu ezinkulu zobuchopho. I-cerebrum iyisakhi esikhulu kunazo zonke, eselulekela phezulu kwekhanda liye ezingeni lendlebe. I-cerebellum incane kune-cerebrum futhi itholakala ngaphansi kwayo, ngemuva kwezindlebe ezibheke emuva kwekhanda. Isiqu sobuchopho sincane kunazo zonke futhi sitholakala ngaphansi kwe-cerebellum, sehlela phansi sibuyele emuva entanyeni.

I-cerebral cortex yingxenye engaphandle ye-cerebrum, ebizwa nangokuthi "into empunga". Idala imicabango ebucayi kakhulu futhi ilawula ukunyakaza komzimba. I-cerebrum ihlukaniswe izinhlangothi ezingakwesobunxele nangakwesokudla, ezixhumana zodwa ngesiqu esincane semicu yezinzwa. Ama-grooves namafolda kwandisa indawo engaphezulu ye-cerebrum, okusivumela ukuthi sibe nenani elikhulu kakhulu lezinto ezimpunga ngaphakathi kogebhezi.

Uhlangothi lwesobunxele lobuchopho lulawula imisipha engakwesokudla komzimba futhi okuphambene nalokho. Lapha, uhlangothi lwangakwesobunxele luqokonyiswa ukukhombisa ukulawula ingalo yangakwesokudla nokunyakaza komlenze, kuthi uhlangothi lwangakwesokudla lobuchopho luqokonyiswe ukukhombisa ukulawula ingalo yangakwesobunxele nokunyakaza komlenze.

Ukunyakaza kokuzithandela komzimba kulawulwa yisifunda se-lobe engaphambili. I-lobe engaphambili futhi lapho sakha khona ukusabela okungokomzwelo nezinkulumo

Kunama-lobes amabili we-parietal, elilodwa ohlangothini ngalunye lobuchopho. Ama-lobes weparietali atholakala ngemuva kwe-lobe engaphambili ngasemuva kwekhanda nangaphezulu kwezindlebe. Isikhungo sokunambitha sitholakala kuma-lobes weparietal.

Yonke imisindo icutshungulwa ku-lobe yesikhashana. Futhi zibalulekile ekufundeni, kwimemori, nasemizweni. I-lobe ye-occipital itholakala ngemuva kwekhanda ngemuva kwe-lobari ye-parietal ne-temporal.

I-occipital lobe ihlaziya imininingwane ebonakalayo evela ku-retina bese icubungula lolo lwazi. Uma i-lobe ye-occipital yonakala, umuntu angaba yimpumputhe, noma ngabe amehlo akhe aqhubeka nokusebenza ngokujwayelekile

I-cerebellum itholakala ngemuva kwekhanda ngaphansi kwe-lobes ye-occipital neyesikhashana. I-cerebellum idala izinhlelo ezizenzakalelayo ukuze sikwazi ukwenza ukunyakaza okuyinkimbinkimbi ngaphandle kokucabanga.

Isiqu sobuchopho sitholakala ngaphansi kwama-lobes wesikhashana futhi sandiselwe phansi entanjeni yomgogodla. Kubaluleke kakhulu ekusindeni ngoba kuxhuma ubuchopho nentambo yomgogodla. Ingxenye ephezulu ye-brainstem ibizwa nge-midbrain. I-midbrain yingxenye encane yesiqu sobuchopho esitholakala phezulu kwesiqu sobuchopho. Ngezansi nje kwaphakathi kobuchopho kukhona amaponi, futhi ngaphansi kwamaponi kukhona i-medulla. I-medulla yingxenye yobuchopho obusondele kakhulu entanjeni yomgogodla. I-medulla, nemisebenzi yayo ebucayi, ilele ngaphakathi ekhanda, lapho ivikeleke kahle ekulimaleni yingxenye ejiyile engaphezulu yogebhezi olweqile. Lapho silele noma silele, ukushaya kwenhliziyo yethu, ukuphefumula nomfutho wegazi kuyaqhubeka nokusebenza ngoba kulawulwa yi-medulla.

Futhi lokho kuphetha ukubuka konke okujwayelekile kwezakhi zobuchopho.
